The company "Policervis" offers services for the insulation of warehouses with foamed polyurethane. An effective insulation system allows you to create an optimal microclimate in warehouses and maintain normalized temperatures for storing goods or equipment.

Practical insulation for warehouses

The performance properties and installation technology make it possible to consider foamed polyurethane insulation as effective solution for thermal insulation of warehouses.

The main properties of the heater include:

long service life;
water resistance and heat resistance;
low thermal conductivity;
rodent resistance;
100% adhesion to any kind of substrate.

The polymer material is environmentally friendly and equally effective for external and internal insulation.

PPU installation technology

Foamed polyurethane is applied by spraying with special equipment. This method allows you to create a seamless coating of the required thickness on surfaces of any complex shape. Due to good adhesion, the material is mounted without battens and mechanical fasteners. The time of foam hardening does not exceed several hours. The method of application and the absence of fasteners make it possible to minimize the time losses for thermal insulation.

Foreword. In this article, we will consider an important issue for companies whose activities are related to the rental and operation of warehouses. In order to reduce the organization's costs for heating storage facilities and create a comfortable climate for the work of employees, it is necessary to insulate the walls of the warehouse, roof, floors and hangar gates. It is to this question that we decided to pay attention in this material.

Insulation with foil insulation

A feature of the warehouse is a huge space with concrete floors and large gates, such warehouses are often impossible to heat to a comfortable temperature for a person. So that the warehouse owner’s electricity bills are not ruined, it is necessary to insulate the warehouse for the winter: get rid of “cold bridges” and seal up leaks of warm air.

First of all, it is necessary to think over the process of loading and unloading, which would take the minimum possible time to open the gate. It is also necessary to pay attention to the thermal insulation of the roof, concrete floors and walls from the inside in the warehouse. Let us further consider the question of the better to insulate a warehouse for the winter and describe some ways to insulate warehouses from the inside.

How to insulate a warehouse from the inside

The insulation of warehouses and hangars differs from the thermal insulation of a residential building, since it requires the processing of huge spaces, structures and work at height. In addition, it is often impossible to stop the activity of the warehouse even for a while, therefore, all repair work will have to be carried out by builders inside at night or during the work of the enterprise.

How can I insulate a warehouse from the inside for the winter:

1. Mineral wool(glass wool) - a classic and fairly cheap material. Mineral wool is fireproof (this is a significant plus for a warehouse where flammable substances or goods are often stored), the material is not subject to decay and decomposition. The disadvantage of basalt wool is the ability to absorb moisture and the low density of the plates - this requires the construction of a frame where the mineral wool plates will be laid, and the protection of the thermal insulation with a vapor barrier membrane from getting wet.

2. Styrofoam or foam- the cheapest insulation, the plates are easy to mount and there is no need to stop production. Extruded polystyrene foam has the best characteristics and is perfect for insulating a concrete floor in a warehouse, roofing and walls, as the material is very durable, while being lightweight and not afraid of high humidity. The foam is less durable, in addition, the insulation is highly flammable and emits harmful substances during combustion, which is unacceptable for fire safety.

Hangar vaults insulated with polyurethane foam

3. Spray foam- a very popular way to insulate roofs and walls in industrial premises and warehouses. Sprayed polyurethane foam (PPU) is a lightweight and durable material, non-flammable and has low thermal conductivity.

PPU is quickly applied and forms a seamless coating, resistant to moisture and without "cold bridges".

The material can be applied to any surface: wood, concrete, metal. The disadvantage of this insulation is the high cost, as well as the impossibility of carrying out all the work with a working warehouse.

How to insulate a cold warehouse in winter

How to insulate a gate in a warehouse

To insulate the gate in the warehouse, you can use expanded polystyrene or foam plastic. The material is light, durable, not afraid of precipitation. You can use sheets 50 mm thick, which are inserted into a frame made of 50x50 mm wood bars. The beam is pre-treated with an antiseptic, and all remaining seams between the foam sheets are sealed with mounting foam.

When the entire gate area is insulated, moisture-resistant plywood or OSB is mounted on top. The whole technology is no different from garage door insulation. Also, the gate can be insulated with mineral or glass wool, which also fits into a frame made of wood bars. The width of the beam must correspond to the thickness of the thermal insulation layer, which can be calculated on the calculator.

Before laying the basalt wool, the entire frame and gate are covered with a moisture-proof membrane. After laying the insulation, the frame is again closed with moisture insulation, so that the mineral wool is protected from getting wet from all sides. Next, bars are attached to the frame to create a ventilation gap so that moisture evaporates from the surface of the film, and the gates are sewn up with plywood or OSB.

How to insulate a roof in a warehouse

Insulation of the hangar roof is often difficult due to the significant height of the structure and its lightness, which is why it is often impossible to use heavy structures. A simpler, but more expensive way to insulate a roof in a warehouse is to hire specialists who will quickly spray polyurethane foam on the structure. Polyurethane foam will create a continuous layer without seams and will not load the roof of the hangar.

A cheaper, but at the same time labor-intensive method is the creation and insulation of the ceiling ceiling. In many cases, this method is simply impossible to implement due to the significant loads on the light structures of the walls and roof of the hangar. If the warehouse has concrete walls and ceilings, then there should be no problems. You can use any roll and slab insulation for this.

Slabs of mineral wool or expanded polystyrene should be laid in a pre-designed timber frame. The distance between the bars should be made 1-1.5 cm less than the width of the mineral wool or glass wool sheets so that the insulation fits as tightly as possible to the bars. Additionally, the thermal insulation should be fixed with a dowel - with fungi and covered with a vapor barrier to protect it from moisture.

How to insulate a concrete floor in a warehouse

Scheme of insulation of concrete floors on the ground

The concrete floor should be insulated even at the stage of the construction of the hangar. Thermal insulation is produced by the method of warming the earthen floor with foam plastic or foam plastic. Insulation plates are laid on the previously leveled soil (for this, the foundation should be poured from the inside with soil or sand). A caracas of reinforcement is knitted on top, and the floor in the hangar is poured with a thick layer of concrete.

If it is required to insulate the floor in the hangar after the completion of construction, then this work will require significant financial outlays. Since it will be necessary to re-lay the insulation and pour concrete where cars and forklifts will drive. In those rooms where there will be no significant load, it is possible to insulate the floors along the logs, using foam plastic or mineral wool as a heat insulator.

This floor insulation technology was described in detail earlier in the article “Which is better for floor insulation in a wooden house” and will not be difficult. All work on the insulation of the hangar for the winter from the inside can be done in stages, so as not to completely stop the work of the organization.

The issue of warming storage facilities is as acute as the problem of reducing heat loss in winter with open gates. Sometimes vestibules are used for these purposes, which greatly complicates the process of loading and unloading. Another popular option is the use of heat guns, which are able to quickly warm up the air in the room after it cools down with the gate open.

Roof construction device

The device of roof structures is divided into attic and non-attic. industrial buildings are made at a slight slope to drain precipitation, usually they are not attic. Attic roof types are mainly pitched structures with an angle of inclination of about 30-70 ° and load-bearing elements in the form of rafters, large panels and trusses.

On the rafters and trusses, a crate is laid, more often from wooden beam, or boardwalk. It serves as the basis for a roof made of rolled waterproofing materials. Additionally, before laying the rolled carpet, if there is such a need, steam and heat insulation are made with special materials.

With spans of 10-12 m, they are built as a system with hanging rafters. It is a structure, the main bearing part of which is roof trusses, based on the walls of the building. A vertical headstock (suspension) is installed in the center of the farm. It is connected to the walls by rafter legs, which serve as the supporting basis for the roof. To give the structure rigidity, they rest against the struts coming from the base of the beam.

For this design, the following materials are most often used:

for hanging rafters- boards or bars;
for the lower belt and racks working in tension - steel profile or pipes;
for farms - reinforced concrete or steel.

Single or gable roofs from large ribbed reinforced concrete panels are built with a central support, which can serve as inner wall. The panels rest on it and the outer walls of the structure. The span of the structure, as a rule, is 6-6.4 m. Fastening - steel anchors. An asphalt or cement screed is applied to the panels and a rolled carpet is glued. Now the panels are mainly made of water-resistant concrete, which does not need waterproofing, so there is no need for it.

Industrial roofs of buildings with a height of more than two floors are protected with brick parapets.

The industrial roof of a non-purlin scheme is formed by reinforced concrete slabs, which are both the supporting element and the base of the roof. A cold roof is built from heavy concrete, after laying the plane is leveled with asphalt mastic or cement mortar with the subsequent sticker of a rolled carpet.

Foam concrete, mineral heaters are used for insulation, a screed is made on top of them and rolled waterproofing is glued.

Sometimes flat roofs do it without bias. To avoid overheating, in some cases they are protected by flooding with water by 5-15 cm, before the onset of winter, the water is drained.

Chimneys and ventilation outlets need a special device for adjoining the roof to them. To do this, collars are made of tin, closely adjacent to the pipe, the collar is placed above the roof plane. If the coating is asbestos-cement slate, then the collar from the side of the ridge is inserted under the roof, and on the side of the overhang it is let on top of the slate sheets.

Industrial buildings with a height of more than two floors are protected with brick parapets or gratings according to MRTU 20-4-65.

Basic requirements for thermal insulation of industrial and administrative buildings

Speaking about the thermal insulation of an industrial building, we immediately mean the presence of an aggressive environment, large areas, metal structures and, as a rule, short deadlines for the execution of work. Therefore, the materials that will be used in the insulation of an industrial building should:

mounted quickly, so as not to slow down production processes for a long time;
do not be afraid of alkaline and acidic effects that are present in the air;
if possible, protect the metal structures of walls and roofs from excessive moisture and corrosion;
cost cheap.

If there is a question about the insulation of an administrative building, then there are also some requirements:

insulation should not spoil the overall aesthetic appearance of the building;
be mounted quickly, as the administrative building is constantly in sight;
thermal insulation must be low price
;
the life of the insulation should be as long as possible in order to avoid costly repairs.

And in both cases, of course, do not forget about EFFICIENCY. The building must maintain the required temperature.

As we can see, there are many requirements for the insulation of industrial and administrative buildings, and they are all quite serious. But for a sprayed polyurethane foam insulation, this is not a problem.

Materials for insulation of industrial buildings

It is important to remember that the specificity of thermal insulation of industrial buildings is primarily due to their purpose and location. In all cases, complex work is required to improve the overall thermal protection of the building.

Therefore, it is quite logical that for each individual part of the structure, different material suitable for specific purpose. You can read more about how to insulate buildings here. For example, for roofing, mineral wool slabs with combined insulation are best suited.

In general, the process of industrial roof insulation includes several stages:

Laying of galvanized steel profile sheet.
Installation of vapor barrier protection (polyethylene film).
Insulation installation ( mineral wool).
Installation of expanded polystyrene plates with subsequent laying of the roofing system.

Stages of thermal insulation of the walls of industrial buildings

The load-bearing walls of the structure must be made of brick, concrete and its varieties (foam concrete, aerated concrete). The structure of these materials has specific features that prevent the passage of cold air.

When using cement or bituminous glue, PPS boards are installed. It is necessary to use only those varieties that are designed specifically for the facades of the premises. For greater safety, you can install fire cuts made of mineral wool.

The final stage is to give the walls the necessary appearance with the help of decorative plaster. To do this, a reinforcing mesh is applied over the plates, and then a layer of plaster.

This method of insulating the walls of industrial buildings is very popular in Europe. Its peculiarity lies in the fact that after using such a technology, it is not necessary to update the insulation itself. It is enough only from time to time to change the outer decorative layer, which can crumble over the years.

Speaking about industrial insulation, it is worth considering the fact that the thermal insulation of industrial buildings should be comprehensive. In this regard, we must not forget about the insulation of the floor.

Stages of floor insulation

Installation of floor slabs to stabilize the future insulated structure.

Laying PPS slabs. Their size depends on the area of \u200b\u200bthe room and is selected individually in each case.

Installation of a waterproofing layer.

The final stage is the screed. Laying plywood and gypsum fiber to increase thermal insulation properties floor, as well as the stability of the entire structure.

This insulation technology is used, as a rule, for reinforced concrete coatings of a room (industrial buildings). She possesses the best performance and is designed to increase the coefficient of thermal stability of the building as a whole.

Features of industrial thermal insulation using polyurethane foam

The above methods are classic and give good performance in terms of thermal protection. However, technology does not stand still, and the thermal insulation of industrial buildings is also taking on new forms. In particular, this applies to the use of polyurethane foam (PUF), applied by spraying.

Long service life. Subject to the technology using modern equipment, PPU can last more than 50 years.
Safety for human health.
It withstands negative environmental influences and is resistant to the occurrence of fungi and mold.
No technological seams. Thereby thermal insulation characteristics industrial buildings are increasing significantly.
The process of spraying PPU can be carried out in the shortest possible time, which is also a plus for the entire production rhythm.

Of course, when insulating industrial facilities, there are always many nuances. This also applies to the choice of materials and the method of application (which in turn depends on the purpose of the object and its location).

Ignoring at least one of the points can significantly reduce thermal protection. industrial premises which will inevitably lead to additional costs in the future. The second mandatory condition is an integrated approach to the entire industrial facility. Under these conditions, the best effect is achieved. And the process of insulating an industrial building will be practical and efficient.

What material should be chosen for the thermal insulation of the warehouse

If you decide to insulate your warehouse, then it is best to choose polyurethane foam for this purpose. It has a lot of advantages:

Ease of installation. Insulation work with this material take no more than 1 day. Agree that such terms are quite attractive;

Saving. In addition to the fact that your goods will always be safe, you can save on heating. Insulation of warehouses with polyurethane foam reduces energy costs by 50%. A one-time investment in thermal insulation will help you save long years;

Durability. polyurethane foam
can serve as a heater for several decades.

Warehouses are designed to store various materials and goods. Often, for the storage of certain groups of goods, special conditions, including certain temperature, humidity, general microclimate. In order to create these conditions, the premises must be isolated as much as possible from the effects of environmental conditions, that is, sealed and thermally insulated. In a cold climate, the facades of houses are not able to retain heat inside the premises by themselves. As a result, there are high heating costs, the low efficiency of which is due to the high thermal conductivity of building materials.

POLYURETHANE FOAM IS THE BEST SOLUTION FOR WAREHOUSES

To date, for the thermal insulation of rooms of any type, many modern heaters are used, which are designed to solve various problems. However, for the insulation of warehouses, polyurethane foam, or polyurethane foam, is best suited. This heat insulator has unique characteristics, so far unattainable for other materials. In particular, polyurethane foam has the lowest coefficient of thermal conductivity, which makes it possible to recoup investments in thermal insulation in just two seasons, and subsequently save up to 50% on energy resources for a long time to come.

PROPERTIES OF POLYURETHANE FOAM SO NECESSARY FOR WAREHOUSE INSULATION

The only drawback of PPU can be called exposure to ultraviolet rays. However, this problem is solved by simply painting the thermal insulation with any paint that will protect the surface.

Naturally, it is impossible to create the necessary microclimate in the warehouse only by thermal insulation of the premises. Therefore, in combination with a heater, it is necessary to take care of high-quality, well-thought-out ventilation. Such a complex will help make your warehouse an ideal place to store any goods.

Most modern private entrepreneurs, as well as various firms, enterprises and factories, have warehouses at their disposal. Usually stored in warehouses finished products, goods for sale, expendable materials raw materials and more.

Whatever is in these structures, if the warehouse is not properly insulated, in the cold winter or hot summer periods of the year, the contents of the warehouse risk becoming unusable or losing their original characteristics.

Benefits of using polyurethane foam as a roof insulation

Roof insulation using polyurethane foam has many advantages over other heaters:

there is no need to dismantle the old roof;
polyurethane foam insulation has the lowest coefficient of thermal conductivity, which makes it possible to reduce the thickness of the thermal insulation layer;
no special preparation of the roof surface is required;
PPU material has great adhesion to most building materials;
the ability of PPU to flow around surfaces of any shape and any kind of bends;
fill defects, cracks, forming a continuous even seamless coating;
short terms of performance of work on thermal insulation of the roof with the use of polyurethane foam (speed of work - about 300 m2 per day);
icicles do not form on the roof insulated with polyurethane foam.

Due to the unique properties of polyurethane foam, it is possible to insulate the roof both from the outside and from inside. When applying polyurethane foam to outer surface roofs, polyurethane foam coating must be protected from sunlight. For these purposes, you can use liquid rubber or urethane mastic. Coatings made of these materials will protect the heat-insulating layer of polyurethane foam from ultraviolet rays, create additional waterproofing of the roof and increase its service life.

When using sprayed rigid polyurethane foam for roof insulation in comparison with traditional methods thermal insulation saving time is 80%, and saving Money- fifty%. In terms of quality and durability, polyurethane foam insulation technologies are many times superior to other methods of insulation.

When repairing polyurethane foam roofs, there is no need to remove the worn coating, in addition, all structures present on the roof are additionally sealed, and the absence of thermal bridges prevents the formation of condensate. During work on thermal insulation of the roof with the use of polyurethane foam, it is not necessary to stop the activity of the entire room, which is also an important advantage of using polyurethane foam.

Polyurethane foam is applied to the surface with a special spraying machine. high pressure and after a few minutes the polyurethane foam becomes rigid.

The nuances of fastening insulation

Whatever material is chosen, it must be firmly fixed to the base. For these purposes, you can use two methods:

Bonding on bitumen. A laborious and expensive process, justified only if there is concrete base, since more expensive specialized dowels are not required and there will be no need to drill holes for them.
Mechanical fastening with special telescopic dowels. They have a very wide cap, due to which they cannot pierce the waterproofing and thus do not violate the tightness. flat roof.

There is a building rule according to which the waterproofing carpet is attached to the insulation in the same way that it is attached to the base. At mechanical way fasteners, it is better to use a polymer-bitumen deposited material as a vapor barrier. Its special elasticity helps, without consequences, to tighten small holes, inevitably punched by a dowel, on which the insulation is attached. If two-layer insulation is used, the slabs must be laid "in a run-up" so that the joints of the slabs of the lower layer are necessarily covered by the upper one. In this case, the so-called "cold bridges" are not formed. Each insulation plate is fixed with at least two dowels.

The layers of the "roofing cake" must be securely fastened

The temperature and comfort inside the building largely depend on the competent insulation of a flat roof. By choosing the right materials and carefully observing construction technology, you can get a magnificent structure that will serve flawlessly for many years both as a traditional covering and as a base for a recreation area, terrace or roof garden.

Calculation of the roof covering of an industrial building

Required resistance to heat transfer.

The selection of the parameters of the enclosing structure is carried out according to the value of the required resistance to heat transfer, calculated by the formula:

- resistance to heat transfer of the enclosing structure; - the estimated air temperature inside the room (); - minimum outdoor temperature (); n- coefficient taking into account the location of the enclosing structure, is taken according to the table SNiP -3-79 (we accept for the roof n=1); - heat transfer coefficient, depends on the smoothness of the inner surface of walls and ceilings and takes values according to SNiP (smooth ceilings); - heat transfer coefficient, determined according to SNiP (for roofing); - the normative temperature difference between the air temperature in the room and the temperature of the internal surfaces of the enclosing structures, is taken according to SNiP (based on the condition "industrial buildings with a normal mode" we accept); R- thermal resistance of the material of construction, determined by the formula

is the thickness of the total layer,

Thermal conductivity for normal operation and normal climate, i.e. mode A:

Knowing, we derive from the formula (*) the thickness of the roofing materials:

where is the thickness of the insulation, from here,

For roof insulation we use mineral wool mats, and for waterproofing - three layers of roofing material on a bitumen base with a total thickness of 15 mm.

Thermotechnical characteristics of roofing insulation materials.

Table number 2.

- mineral wool mats with density.

As waterproofing:

- roofing material at density and - bitumen at density. From here we find the average value of thermal conductivity for waterproofing: .

Substitute these values into the formula (**):

We round the resulting value to a multiple of 50 mm. Then, the thickness of the mineral wool layer should be at least 0.05 m

Examination.

Because - the condition for heat transfer of the building envelope is met, therefore, the calculation is correct.

Thermal inertia:

— thermal resistance of the i-th layer.

S 1 \u003d 0.46 - heat absorption of mineral wool, W / (m2 * C);

S 2 \u003d 4.425 - average heat absorption of roofing material and bitumen, W / (m2 * C);

d 1 \u003d 0.05 - thickness of the mineral wool layer, m;

d 2 \u003d 0.015 - the thickness of three layers of roofing material on a bitumen base, m.

l 1 \u003d 0.05 - thermal conductivity of mineral wool, W / (m * C;

l 2 \u003d 0.19 - the average thermal conductivity of roofing material and bitumen, W / (m * C).

Conclusion: for roof insulation we use mineral wool mats, and for waterproofing - three layers of roofing material on a bitumen base with a total thickness of 15 mm.

As filling the window openings, we choose double glazing in metal frames.

Advantages of polyurethane foam building insulation

Firstly, the thermal conductivity of polyurethane foam is quite low, therefore, even with a small thickness of this insulation on the roof or walls of a building, one can always speak of high efficiency (30 mm polyurethane foam at a coefficient of 0.019 W / m * K).

Secondly, the closed cell structure of polyurethane foam does not allow water or steam to pass through, so the water absorption rates of polyurethane foam are also low. And this speaks not only of preservation of insulation properties
throughout the entire service life, but also about the anti-corrosion protection of metal structures.

Thirdly, polyurethane foam is mounted using a foam generator sputtering
, which implies the absence of fasteners, guides, as well as the acceleration and simplification of the installation process. In addition, the sprayed polyurethane foam is held so tightly that its dismantling is possible only by rough physical methods.

Fourthly, PPU is not afraid of exposure to any chemical reagents (except for concentrated alkalis and acids).

Fifthly, polyurethane foam is applied to the surface with a seamless layer that completely repeats its structure and shape, so you don’t have to worry about a damaged facade. When insulating the facade of a PPU building, you can always paint it, apply plaster over it or use a ventilated facade system.

Choice of thermal insulation single-layer or double-layer

First of all, you should consider the installation of a flat roof - insulation can be planned in two ways:

Single layer insulation system. home distinguishing feature: the entire insulation layer is made of a single-density flat roof insulation. If it is planned to equip an operated roof, then a thermal insulation layer is laid over concrete screed. Such a system is most often used in the repair of old roofs or in the construction of garages, warehouses and industrial buildings. The two-layer thermal insulation system is arranged differently. The top layer with a thickness of 30-50 mm is made of a heater of increased strength and density. It is designed to redistribute the mechanical load. The lower one, with a thickness of 70 to 170 mm, performs the main heat-insulating function

This design allows you to significantly reduce the weight of the roof and, accordingly, reduce the load on the floors, which is very important when repairing old buildings. There are modern materials that combine the properties of both layers.

These insulations have a hard top edge and a softer bottom edge. The installation of such plates is very fast and reduces the time and labor costs for the installation of the coating.

The two-layer system guarantees the absence of through seams in the thermal insulation layer

Antipyretics for children are prescribed by a pediatrician. But there are emergency situations for fever when the child needs to be given medicine immediately. Then the parents take responsibility and use antipyretic drugs. What is allowed to give to infants? How can you bring down the temperature in older children? What medicines are the safest?

For the development of industrial production, wholesale trade, the logistics business always requires a decent amount of warehouse space. In addition, warehouses-shops and Internet trading platforms that do not have separate areas for the sale of goods are becoming more widespread.

What is the difficulty

Of course, it is not difficult to build a small warehouse building from materials that already have heat-saving properties. But if we are talking about areas and volumes for organizing the storage of products, raw materials or goods, calculated in hundreds and thousands of square and cubic meters, then traditional ways construction will not be economically justified.

Hangars and warehouses of large areas are most often built according to frame technology or using prefabricated structures. An example is the well-known arched metal structures assembled from wave-shaped steel sections.

The steel of the sections does not retain heat at all in winter and does not protect the internal volume from heating in the sun in summer. There are also warehouse structures made of concrete slabs also in need of thermal insulation. What methods and materials are used to improve hangars and other large premises?

Methods for insulating structures made of metal and concrete

Among the variety of ways to preserve heat in a warehouse, several basic and acceptable in terms of efficiency deserve attention.

Method 1: Create an Inner Path

The method of insulation by building an internal contour consists in the construction of a light, insulated, non-bearing frame structure inside the hangar.

Installation can be done according to various technologies- using wooden slatted or metal profile frames with the installation of foam or slab insulation in them and then facing with panels.

Significant disadvantages of the method are the reduction of the useful area of the warehouse and the high cost of construction.

Method 2: insulation with basalt and glass wool slabs

Warming with slab, basalt or glass wool material as a method is effective in terms of heat conservation, but inconvenient to implement. In fact, this is the same option as with the internal contour, but the frame is mounted directly on the walls of the warehouse.

This additionally loads the hangar sections and may affect its stability. In addition, the fastening of rails or profiles to the steel of the walls may present a certain difficulty. Another disadvantage of this method is the moisture that inevitably accumulates in the thickness of the insulation and does not go outside.

Method 3: foam as a heater

Insulation with polyurethane foam has become popular. This material exists in two forms - in the form of plates and in the form of a liquid mixture, which, after application, foams itself. Plates insulate the outer surfaces of wooden or concrete walls, and the walls inside the premises are treated with foam. Liquid polyurethane is probably the most suitable insulation for steel structures.

Construction foam has good adhesion to any surface. Its heat-conducting properties do not depend on the shape of the walls, and the degree of insulation can be adjusted by the thickness of the layer. The disadvantage can be considered the impossibility of processing at negative temperatures of air and walls.

Materials: properties and comparison

Let's consider several main characteristics that are essential specifically for insulation of warehouses and hangars:

thermal conductivity, i.e. the degree of insulation of a layer of a certain thickness;
flammability or the ability to sustain combustion. The security of the premises from fire depends on this parameter;
specific gravity or the load that the building structure will bear from insulation.

This insulator has the following features:

specific thermal conductivity: about 0.030 W/m*K. This figure characterizes both glass wool and basalt materials;
combustibility: do not burn and do not support combustion. Glass wool slabs withstand temperatures up to 400°C without loss of properties, and basalt fiber slabs - up to 1000°C. The walls of the warehouse covered with basalt fiber are able to withstand open fire for a long time;
specific gravity: depends on the density of the board and ranges from 35 kg/m3 to 180 kg/m3. To insulate a steel wall, 15 cm of a layer with a density of 100 kg/m3 is sufficient. Thus, on a plot of 1 m2, the load will be 15 kg.

Styrofoam and expanded polystyrene

Styrofoam or expanded polystyrene in a solid, slab version have the following qualities:

thermal conductivity: for polystyrene - 0.037 kg / m3, for expanded polystyrene - 0.027 kg / m3, which is quite comparable with the characteristics of mineral wool;
degree of combustibility: polystyrene foam and polystyrene foam can burn, but in modern production fire retardants are added to them, which makes it possible to assign a combustibility class G1 to these materials and call them non-combustible. The heat resistance of foam materials is low - they do not withstand heating even up to 250-270 ° C, and when burned, they emit gases dangerous to humans;
specific gravity: foam plastic - 100 kg/m3, expanded polystyrene - 40 kg/m3, polyurethane foam (mounting foam) - 40-80 kg/m3. 1 m2 of foam plastic with a layer of 15 cm will have a weight of 15 kg, polystyrene foam - only 6 kg, and polyurethane foam - from 6 to 12 kg.

Heaters such as mounting or building foam have the same characteristics as polyurethane foam board materials.

Comparative analysis

An elementary comparison of the characteristics shows that the degree of insulation of all materials is almost the same, the minimum weight is polystyrene foam and polyurethane foam. Moreover, the calculation did not include the weight of the frame structure, which is necessary if mineral wool or hard foam material is used. As protection against fire, it is most reliable to use stone wool. However, liquid polyurethane is the easiest to install.

Another important characteristic is the cost of materials. The most expensive are stone wool insulation, the cheapest are foam boards. The choice of thermal insulation for a warehouse depends on the design features, wall material and financial capabilities.

Installation work

The technology of insulation with fibrous and slab materials can be described in the following steps.

The frame is assembled from wooden slats (usually for foam) or metal profiles.

The frame is fastened to the walls either with self-tapping screws or with dowels, metal profiles can be attached to steel structures with wire and welding. The thickness of the frame elements must correspond to the thickness of the insulation sheets.

To prevent the accumulation of moisture inside the mineral wool layers, it is advisable to place a vapor barrier on both sides, and if the installation is carried out outside the walls, a windproof vapor-permeable membrane. Films should be fastened with slack so that thermal fluctuations in the dimensions of the hangar structures do not damage them.

The frame is usually placed inside the building. However, in order to preserve useful volumes, it is possible to insulate the outside, followed by cladding.

Slab laying

Plates, sheets or rolls are placed between the slats or frame profiles and fixed. Possible joints are carefully sealed with scraps of the same material or foam.

Facing

It is carried out not only for the purpose of appearance more presentable, but also to prevent damage to the insulation. Another technology is used to apply a layer of polyurethane to the walls. The liquid composition is applied by spraying from special sprayers. Work must be carried out in protective clothing, ventilation is organized in the room.

After application, the composition expands on its own for some time and fills all the bumps and cracks in the walls. Freezing time is about 1 hour. As a result, a textured surface appears, which can subsequently be painted with water-based paints.

Warming various types hangars with sprayed polyurethane foam in the agricultural complex

In this article, we will try to reasonably substantiate the thesis, stating that today one of the most effective, inexpensive and quick ways thermal insulation of large non-residential premises is insulation with sprayed polyurethane foam density PPU from 45-60kg/m3 freon based.

Probably, it will not be a revelation for anyone that a building of a huge area and height, which does not have high-quality thermal insulation, can bankrupt its owner in one winter due to astronomical heating costs. You do not need to have knowledge in the field of higher mathematics in order to calculate how much it will cost to heat volumes measured in tens of thousands of cubic meters.

If such a building is not located in a subtropical climate zone and the average winter temperature outside its walls fluctuates below zero on the thermometer scale, the only solution to the problem of maintaining the required temperature inside is high-quality thermal insulation. No one will argue with this axiomatic statement. Another issue is the choice of the type of this thermal insulation and the material on the basis of which it will be implemented. Let's make a brief analysis of the main heat-insulating materials and impartially compare their advantages and disadvantages.

The main types of heat-insulating materials for the insulation of the hangar

First of all, it should be noted that all heat-insulating materials are divided into two main groups - inorganic and organic.

Inorganic thermal insulation materials

The most common inorganic thermal insulation materials include the following:

mineral wool;

glass fiber (glass wool);

foam glass.

We will not go into the intricacies of the technology for the production of these materials, since this is of little interest to the end user. Let's take a look at their properties.

All of the above materials are characterized by fire resistance, low thermal conductivity and resistance to chemical and biological (mold, pests) influences. However, despite the above advantages, they also have a number of serious disadvantages. Mineral wool and fiberglass are characterized by high hygroscopicity, which leads to the fact that these heat-insulating materials become completely unusable after a few years, if they are not impregnated with special water-repellent (giving water-repellent properties) compounds, and mineral wool also requires mandatory waterproofing.

The above disadvantages are devoid of such insulation like foam glass, but it has a high rigidity, which limits its use in conditions where the surface has a complex shape.

For the most part, the above-mentioned heaters are supplied in the form of blocks, which are fixed with the help of fasteners of one type or another on the walls of the room to be insulated. This inevitably leads to the fact that the integrity of the structure is damaged, which, in turn, reduces its service life to a greater or lesser extent. It is also possible to fix these materials with glue, but this method also has its drawbacks: the glue does not hold so firmly, and as a result of temperature changes, delamination of certain sections of the insulation may occur. With both methods of fastening, due to the fact that the heat-insulating coating is not monolithic, so-called cold bridges will inevitably occur, reducing the overall effectiveness of the heat-insulating layer.

You can also mention in this section such material as foam concrete, which is not just t heat-insulating material, and building material with low thermal conductivity. But it's still construction material not a heater.

Organic thermal insulation materials

The most common organic thermal insulation materials include the following:

polystyrene or Styrofoam;

polyethylene foam;

polyurethane foam.

We are all familiar with the first type of the aforementioned organic heaters from childhood: which of us did not get our beloved parents, driving a piece polystyrene on glass? This light material 90% consists of air, and air, as you know, is a good heat insulator. Insulation with expanded polystyrene has long been widely used, but this material has one significant drawback - it is very fragile.

Polyethylene foam- one of the most promising modern materials, which has almost all the advantages of polyurethane foam, which will be discussed a little lower. But it also has a significant drawback - like any polyethylene, it is not heat resistant.

Now let's move on to considering the properties of polyurethane foam - a material that combines everything positive traits the aforementioned heat insulators and practically not having their shortcomings.

One of the main advantages of polyurethane foam is the possibility of spraying onto a surface of any size and shape, which results in a uniform layer of heat insulator without any joints or gaps. As a result - complete absence cold bridges.

Due to the fact that polyurethane foam has exceptionally high adhesion to surfaces of almost any type, the possibility of delamination of the heat-insulating layer is completely excluded. In addition, spraying technology significantly reduces the time required for thermal insulation of various buildings.

polyurethane foam very effective and light: a ten-centimeter layer of this substance is equivalent in its heat-insulating properties brickwork two and a half meters thick. The lightness of the material under consideration is due to the fact that it is 85% - 97% (depending on density) consists of air or gases.

Polyurethane foam is heat-resistant and frost-resistant, which allows it to be used in all climatic zones. It does not require any additional waterproofing, and even more than that - its rigid variety itself can serve as an excellent waterproofing agent and is widely used in construction as such.

Another advantage of this material is the excellent soundproofing properties.

In view of the foregoing, we can safely say that it is polyurethane foam that is most suitable for insulating metal structures such as hangars. The lightness of polyurethane foam allows not to overload the structure of sheet metal a little more than 1 mm thick; heat resistance will be needed during the hot summer months when metal gets very hot high temperatures; frost resistance allows you not to fear for the strength of the insulating layer even in severe frosts, and the absence of cracks ensures that not a single drop of precious heat seeps out. If we add to this the speed with which insulation is made with polyurethane foam, it becomes clear that prefabricated hangars and this heater is simply made for each other.

PPU warehouse insulation is beneficial

Many shopping malls, manufacturing companies, stores and firms require their own storage facilities. The key task of such structures is to ensure proper storage conditions for various cargoes. The warehouse must comply with the established storage standards in order to avoid damage to the cargo and change its parameters. Maintaining a certain temperature and humidity regime in a warehouse is a priority for every business owner. An uninsulated warehouse leads to many troubles. There is a problem of maintaining the desired temperature, as a result of which the conditions for storing goods are violated, the work of equipment and people is difficult. Condensation is formed, leading to the appearance of rust on equipment, rotting of floors and dampness of stored products. As a result, electricity costs rise and the company's losses grow. To avoid this kind of consequences is possible only through competent.

Warehouse insulation with polyurethane foam effectively solves a number of problems. This option is rightfully considered one of the best from a technological and economic standpoint. PPU spraying has a mass positive sides, favorably distinguishing it from other outdated alternatives: foam, fiberglass, basalt wool slabs.

Warehouse before and after application of PPU

Warehouse insulation is a rather complicated and costly process. The complexity of thermal insulation of warehouses is due to their design features. Typically, such structures are based on prefabricated frame structures with an arched dome shape. Standard methods of thermal insulation of the premises, applicable for residential buildings, are unprofitable here. In many cases, they do not provide the desired result. Highly effective modern methods come to the rescue - insulation of the warehouse with polyurethane foam.

Warming warehouses in the indicated way provides a lot of advantages. The material is easy to apply. The composition, the components of which are liquid polyol and isocyanate, is sprayed onto the surface under high pressure. When applied, it increases in volume many times over and freezes almost instantly. Therefore, the insulation of warehouses of a large area can be done in a day by only two people. The material has the lowest coefficient of thermal conductivity in comparison with other building materials - 0.019 W / M * K.

PPU can be applied to previously unprepared surfaces made of iron, concrete, brick. A frame is not required for this, as well as the use of special fasteners. The shape of such surfaces does not matter either - the material fits perfectly into all the recesses, filling them with itself. The complex geometry of the warehouse will not be a problem for this polymer. It adheres tightly to all surface irregularities.

Insulation of a PPU warehouse is beneficial from an economic point of view due to the fact that the material minimizes heat loss and energy costs. The resulting coating has no seams, gaps, joints. The polymer layer is equivalent to 500 mm thick brickwork. At the same time, for the insulation of warehouses, a coating with a thickness of 50-80 mm is quite enough. This ensures savings in usable space required for storing products, cargo, etc.

The advantages of polyurethane foam are obvious:

He is not afraid of moisture, which eliminates the need for waterproofing.

Incombustible. The material is not flammable and does not support the combustion process. Garage insulation with polyurethane foam provides fire safety designs.

Able to effectively fill all existing voids.

Provides good sound insulation.

Protects metal structure garage from the appearance and spread of corrosive processes.

Thermal insulation is completely waterproof, it does not form gas condensate, the development of fungus and plaque. The low density of the material leads to a decrease in the overall load on bearing structures. The cellular structure of the material ensures proper vapor permeability of the heat insulator. This serves as a guarantee of the absence of dampness and mold, which is especially important during storage. food products in stock.

PPU does not react with water and chemicals. Excellent adhesion of the polymer provides an excellent bonding of the heat insulator with any kind of walls.

PPU is environmentally friendly and safe for health. It does not contain harmful impurities. It can be freely used for the insulation of food warehouses. It is resistant to burning and temperature extremes, successfully copes with both frost and heat. The combustibility class of the GZ material ensures that it is not capable of becoming a source of ignition and does not support the combustion process. The created thermal insulation can last 30-50 years without any repair.

This material organically combines excellent heat, noise, and waterproofing. PPU warehouse insulation - great way to ensure high-quality thermal insulation of this type of industrial facilities at the maximum speed of work on large areas.

If you are in business, then it is not for us to tell you how important the reliability of storage facilities is. Just imagine that frost hit and all your goods suffered from it. Such situations need to be considered in advance. This will avoid losses.

Insulation of warehouses will help preserve the presentation of your products all year round. This procedure also allows you to save money, since after thermal insulation you will be able to heat your warehouse not as intensively as before. After all, insulated walls retain heat inside the room.

What material should be chosen for thermal insulation of a warehouse?

If you decide to insulate your warehouse, then it is best to choose polyurethane foam for this purpose. It has a lot of advantages:

Ease of installation. Work on insulation using this material will take no more than 1 day. Agree that such terms are quite attractive;

Durability. Polyurethane foam as a heater can last for several decades.

Warehouses are designed to store various materials and goods. Often, for the storage of certain groups of goods, special conditions are required, including a certain temperature, humidity, and in general a microclimate. In order to create these conditions, the premises must be isolated as much as possible from the effects of environmental conditions, that is, sealed and thermally insulated. In a cold climate, the facades of houses are not able to retain heat inside the premises by themselves. As a result, there are high heating costs, the low efficiency of which is due to the high thermal conductivity of building materials.

PROPERTIES OF POLYURETHANE FOAM SO NECESSARY FOR WAREHOUSE INSULATION

The only drawback of PPU can be called exposure to ultraviolet rays. However, this problem is solved by simply painting the thermal insulation with any paint that will protect the surface.

For the development of industrial production, wholesale trade, and logistics business, it always requires a decent amount of warehouse space. In addition, warehouses-shops and Internet trading platforms that do not have separate areas for the sale of goods are becoming more widespread.

What is the difficulty

Of course, it is not difficult to build a small warehouse building from materials that already have heat-saving properties. But if we are talking about areas and volumes for organizing the storage of products, raw materials or goods, in the hundreds and thousands of square and cubic meters, then traditional construction methods will not be economically justified.

Hangars and warehouses of large areas are most often built using frame technology or using prefabricated structures. An example is the well-known arched metal structures assembled from wave-shaped steel sections.

The steel of the sections does not retain heat at all in winter and does not protect the internal volume from heating in the sun in summer. There are also warehouse structures made of concrete slabs, which also need thermal insulation. What methods and materials are used to improve hangars and other large premises?

Methods for insulating structures made of metal and concrete

Among the variety of ways to preserve heat in a warehouse, several basic and acceptable in terms of efficiency deserve attention.

Method 1: Create an Inner Path

The method of insulation by building an internal contour consists in the construction of a light, insulated, non-bearing frame structure inside the hangar.

Installation can be carried out using various technologies - using wooden slatted or metal profile frames with the installation of foam or slab insulation in them and then facing with panels.

Significant disadvantages of the method are the reduction of the useful area of the warehouse and the high cost of construction.

Method 2: insulation with basalt and glass wool slabs

Method 3: foam as a heater

Insulation with polyurethane foam has become popular. This material exists in two forms - in the form of plates and in the form of a liquid mixture, which, after application, foams itself. Plates are used to insulate the outer surfaces of wooden or concrete walls, and the walls inside the premises are treated with foam. Liquid polyurethane is probably the most suitable insulation for steel structures.

Materials: properties and comparison

Let's consider several main characteristics that are essential specifically for insulation of warehouses and hangars:

thermal conductivity, i.e. the degree of insulation of a layer of a certain thickness;
flammability or the ability to sustain combustion. The security of the premises from fire depends on this parameter;
specific gravity or the load that the building structure will bear from insulation.

This insulator has the following features:

specific thermal conductivity: about 0.030 W/m*K. This figure characterizes both glass wool and basalt materials;
combustibility: do not burn and do not support combustion. Glass wool slabs withstand temperatures up to 400°C without loss of properties, and basalt fiber slabs - up to 1000°C. The walls of the warehouse covered with basalt fiber are able to withstand open fire for a long time;
specific gravity: depends on the density of the board and ranges from 35 kg/m3 to 180 kg/m3. To insulate a steel wall, 15 cm of a layer with a density of 100 kg/m3 is sufficient. Thus, on a plot of 1 m2, the load will be 15 kg.

Styrofoam and expanded polystyrene

Styrofoam or expanded polystyrene in a solid, slab version have the following qualities:

thermal conductivity: for polystyrene - 0.037 kg / m3, for expanded polystyrene - 0.027 kg / m3, which is quite comparable with the characteristics of mineral wool;
degree of flammability: polystyrene foam and expanded polystyrene can burn, however, in modern production fire retardants are added to them, which allows us to assign these materials a flammability class G1 and call them non-combustible. The heat resistance of foam materials is low - they do not withstand heating even up to 250-270 ° C, and when burned, they emit gases dangerous to humans;
specific gravity: foam plastic - 100 kg/m3, expanded polystyrene - 40 kg/m3, polyurethane foam (mounting foam) - 40-80 kg/m3. 1 m2 of foam plastic with a layer of 15 cm will have a weight of 15 kg, polystyrene foam - only 6 kg, and polyurethane foam - from 6 to 12 kg.

Heaters such as mounting or building foam have the same characteristics as polyurethane foam board materials.

Comparative analysis

Installation work

The technology of insulation with fibrous and slab materials can be described in the following steps.

The frame is assembled from wooden slats (usually for foam) or metal profiles.

The frame is fixed to the walls either with self-tapping screws or with dowels, metal profiles can be fixed to steel structures using wire and welding. The thickness of the frame elements must correspond to the thickness of the insulation sheets.

The frame is usually placed inside the building. However, in order to preserve useful volumes, it is possible to insulate the outside, followed by cladding.
