How to make floor insulation with penofol with your own hands. Insulation of the floor in a wooden house with penofol from below - Insulation of the floor in a private house with penofol

Penofol is a material made of foamed polyethylene, which simultaneously performs the function of heat and vapor barrier. In addition, the foil layer welded on top of the polyethylene reflects thermal radiation. The material does not have pores - this means that it does not allow air to pass through and, therefore, communicates the properties of a thermos to the insulated structure. Where can it be useful? When warming baths and saunas, which should be a repository of hot and humid air for as long as possible. Also cold floors, for example, a concrete base on the ground floor of the building and a warm floor system device. Let's see how the floors are insulated with penofol in each of these cases.

What happens and how penofol is used

A layer of foamed polyethylene in a foam sheet containing air bubbles, due to which, in fact, insulation occurs, can be a layer from 3 to 10 mm. The foil layer in all modifications of penofol is the same, but can be welded on one side (type "A") or on both sides (type "B"). There is also penofol, which has foil on one side, and an adhesive layer on the other - “self-adhesive” penofol (type “C”). In addition, there is penofol with one layer of foil, which is laminated on top with a layer of polyethylene (ALP type).

Penofol type "A" is usually attached to another insulation (polystyrene, styrodur) with staples or nails. Type "C" can be glued on them or directly on the base. Type "B" is used for stand-alone mounting.

How to lay penofol on a concrete floor

Cold floor for insulation should first be poured concrete screed with expanded clay, but it can be replaced by a layer of foam plastic with a thickness of 5 to 10 cm. A layer of penofol (type "A" or "C") is attached or glued to the foam plastic with an overlap on the walls of 10 cm on each side. Joints are glued with aluminum tape.

The moisture from which penofol protects the structure, not being able to pass through it, will settle on it. To prevent this from happening, it is necessary to arrange a space for ventilation with air vents above the foil layer of penofol - holes through which air can freely pass in order to remove this moisture. To do this, slats 1.5-2 cm wide are stuffed onto the penofol from the side of the foil, creating space for air movement. Logs can play the same role if it is decided to lay a wooden floor. Logs and slats need to be impregnated with an antiseptic or drying oil. They should be laid along the entire length of the floor, retreating 1-2 cm from the walls in increments of 35-40 cm. Boards 2-3 cm thick are laid perpendicular to the lags, and a sheet of plywood 12 mm thick is laid on top. You can use plywood 6-8 mm, but lay it in two layers. The finish can be linoleum or laminate.

The device of the "warm floor" system

Penofol (type “A” or “C”) is placed on the base with foil up, heating elements are laid on it, logs are laid between them, on which batten(1st scheme).

If over heating elements a cement screed will be poured (for example, under a tile), ALP type foam is needed, since cement mortar- an aggressive environment for aluminum, which is coated with penofol (2nd scheme).

In order to isolate the floor from impact noise, foam foam is laid with a margin of 10 cm on each wall. Thus, a "floating floor" system is obtained.

To provide hydro- and vapor barrier, all joints of the canvases are glued with a special aluminum tape.

After laying the heating elements, a reinforcing mesh is laid, after which the floor area is filled with a cement screed. After pouring the solution, the edges of the penofol are trimmed.

This is followed by a rather long period of floor heating and its commissioning.

Insulation of floors with penofol guarantees heat, hydro and noise insulation (reduces impact noise by 20 dB) and ensures uniform heating of the floor surface due to the reflective effect of penofol.

Now on the market building materials There are a large number of heaters with different efficiency. One of the modern heat insulators is penofol. This material is great for light thermal insulation throughout the house, it is also possible to insulate the floor with penofol.

A special production technology gives this material high thermal insulation properties and other characteristics. Overview of properties, scope and insulation technology various surfaces this material will be discussed in this article.

Overview of penofol properties

Penofol is a material made from polyethylene by foaming with special reagents. This polyethylene foam is applied to a foil base, to which it reliably sticks. The foil base greatly enhances the thermal insulation properties of the material due to the reflection of thermal waves inside the room.

Therefore, penofol belongs to the class of reflective thermal insulation. This foil insulation has the following performance characteristics:

• Small material thickness. At the same time, penofol has high thermal insulation properties. This allows you to effectively insulate small rooms where a thick layer of thermal insulation is unacceptable.
• Multifunctionality. This heat-insulating material can be used not only for insulation, it is also recommended to be used as a hydro- or vapor barrier.
• When used simultaneously with other heaters, penofol enhances their main characteristics.

• The strength and durability of the material is achieved through latest technology production. At the same time, the products are environmentally friendly: hazardous substances are not used.
• Large temperature range of application: penofol does not deform at low temperatures (up to -55 °C) and does not melt at high temperatures (up to +110 °C).
• Ease of installation and affordable pricing also add to the popularity of this versatile insulation.

Advice! There are several product classes: A, B and C. Class A insulation has a foil on one side, and the B series material has two. Class C insulation has a foil base on one side, and an adhesive layer on the other, which makes it easier to install in inconvenient areas.

Application area

Penofol has a versatility of application: it is used for insulation and vapor barrier not only for residential premises, but also for industrial facilities. That's far from full list where this material is used:

• Ceiling ceilings.
• Wall insulation.
• Waterproofing and floor insulation.
• Arrangement warm balconies and loggias.
• Thermal insulation of air ducts and technical pipelines.
• Application in the automotive industry for thermal insulation of bodies.

As you can see, the list of applications is quite extensive. We will consider where you can use penofol with your own hands - the home area of ​​\u200b\u200bapplication.

The use of penofol

Even for domestic needs, this versatile material is used quite extensively. Let's consider the main directions.

Most often, penofol insulates floors in wooden house. This process is absolutely simple, you can easily do it yourself, just follow this technology:

1. It is best to remove the old boards and lay several layers of penofol between the lags. In this case, all layers of material must be laid with a foil base inside the room. Then old boards are laid in place or a sheet of plywood is stuffed.
2. Another way is that the heat insulator is laid on top of a wooden covering. One layer of insulation is applied, while the laying is done end-to-end, and the seams must be glued with aluminum tape. Then, sheets of plywood are laid on the laid heat-insulating layer and screwed to the wooden base with self-tapping screws.

Advice! Attach penofol to a wooden base mechanically, for example, brackets are not allowed. If there is a need to fix the insulation, it is better to treat it with glue or use an adhesive-based material.

Thermal insulation of concrete floors

As a rule, penofol for warming concrete floors in a house or on a balcony is used in conjunction with other types of heat-insulating materials. The technology of work in this case is as follows:

The use of penofol in the underfloor heating system

It is very common to use penofol when arranging a system of underfloor heating, both in a private house and in an apartment or on a balcony. The use of this reflective material increases the heat transfer of the entire system by 15–20%, which, at the current cost of energy carriers, is a significant savings. Penofol is used when installing underfloor heating using this technology:

• After the main insulation has been laid, foil material is mounted on it.
• At the same time, it is observed general rule: installation is done end-to-end, the seams are sealed with aluminum tape.

• For this option, a one-sided option is usually used. If fixation of the reflective layer is necessary, then penofol with an adhesive base can be used.
• Then an electric cable or a water circuit piping system is mounted on the foil.

Advice! You can cover the heating elements of the underfloor heating system not only with boards or plywood, but also fill it with cement screed. The foil base of penofol is resistant to various aggressive operating conditions.

Having studied the properties and got acquainted in more detail with such material as foil foam, it is easy to agree with the opinion of professionals that this material is an excellent addition to existing insulation technologies. In addition, this insulation can be used as an independent heat insulator.

Penofol is an effective heat-insulating material that has low thermal conductivity and reliably protects houses from the cold even when laying a thin layer of material. It is often used for floor insulation, since due to its special properties, penofol increases the resistance to heat transfer.

Experts say that floor insulation with penofol is the best option, because thanks to the reflective surface and a large number closed-type pores, the total heat loss is significantly reduced.

Penofol can be perfectly combined with mineral wool and fiberglass for floor insulation, where it will act as a vapor barrier. Application this material will be appropriate in those designs that require not only thermal, but also noise protection, but the thickness of the insulator should be minimal. To insulate the floor with penofol, it is not necessary to additionally use hydro- and vapor barrier membranes, since the material can become their replacement.

Penofol classification

Since the production of penofol began, its properties, scope and structure have undergone tremendous changes. Previously, the material looked like a roll of sewn polyethylene foam, one side of which was foiled with aluminum. With the help of this variant of the material, the thermal insulation of the premises is still performed, since it has high efficiency. In addition to the classic type of penofol, other types of material are produced, which are endowed with a number of useful properties:

1. With one-sided foiling - type "A". It is used in conjunction with other materials for insulation.
2. With double-sided foiling - type "B". Offline use is allowed.
3. Type "C" - one side is covered with special glue and a protective film, and the other side is covered with foil. It is installed by gluing to the surface that requires insulation.
4. Type "R" and "M" - embossed foam with one foil side.
5. Type "ALP" - has one-sided foil up to 14 microns, which is laminated with a polyethylene film.
6. perforated material. It has a special structure that allows air to pass through.

Whatever material the house is built from, create comfortable conditions for living is possible only if thermal insulation work is carried out. Only in this way the house will be warm and cozy. If you decide to take on floor insulation in a wooden house from below, then today it will not be difficult to do this if you choose the right heat-insulating material, and also do all the work strictly according to plan.

Materials used for floor insulation in a private wooden house from below

Going to the building materials store, you can see how wide the range of products in question is. Each heat insulator differs in its size, characteristics and installation method. The choice of this or that material depends on the personal wishes of the owner and the characteristics of the flooring.

Mineral wool

For thermal insulation of a cold wooden floor, mineral wool is often used. The heat insulator is produced in the form of elastic mats and panels. The process of its installation is carried out in one layer.

Mineral wool insulation

The main advantages of the material include:

• high noise and heat insulation performance;
• long service life;
• resistance to fire and high humidity;
• acceptable cost;
• safety;
• resistance to mechanical and chemical factors.

The heat insulator is highly reliable, resistant to low temperatures. It will show its thermal insulation qualities for a long time and will create reliable protection against moisture penetration. But how to insulate the floor with penoplex in a wooden house, and how easy it is to do, is indicated

Expanded clay

Thermal insulation of a wooden floor can occur using expanded clay. This is a bulk material, which is characterized by a porous structure. A heat insulator is produced by firing slate or clay in a special furnace.

Expanded clay insulation for the floor

Expanded clay is a durable and environmentally friendly material. It is characterized by high rates of sound insulation, resistance to fire and frost. But expanded clay has one minus - after a while it becomes too dense due to its own weight and loses its heat-insulating qualities. But how the wet facade is insulated with a heater, this will help to understand

Penofol

This material for floor insulation is produced in the form of rolls. Received on the basis of polyethylene foam, which is covered with aluminum foil on top. The thickness of the material is 3-10 mm.

How to make insulation

The most effective and reliable way to install a heat insulator from the bottom of the floor is laying along the logs - transverse bars, on which the floor covering will be concentrated.

The process of warming is not difficult if you follow the following procedure:

1. Fix the bars on the foundation in increments of 1-1.2 m.
2. Fix chipboard or thick plywood on the boards. For fastening, use self-tapping screws. This stage is important for the installation of the thermal insulation layer.
3. Lay the selected heat insulator on the surface between the bars. The thickness of the laid layer can be different, so the dimensions of the transverse logs must be taken into account.
4. Lay a layer of waterproofing on top of the insulation. Most often, polyethylene film is used. This is not always necessary, since there are a number of heaters that have elevated level moisture resistance.
5. At the final stage of installation, the installation of a wooden covering takes place. It can be old or new material.

How to insulate from a basement

Insulating the basement in a private house is extremely necessary. Thanks to this, it will be possible not only to reduce heat loss, but also to protect the house from dampness and destruction in the future. For thermal insulation work, you can use penoizol, polystyrene, but mineral wool can be used to seal the ceiling from the basement. With the help of polystyrene, the floors and walls of the basement are insulated.

The first step is to prepare the surface. And for this, remove all debris and pollution, walk with an antiseptic and a primer. This will protect the surface from decay, and will also make the adhesion of the material to the surface more durable. Mounting a heat insulator is a simple matter that even a beginner can handle. It is necessary to apply glue to the surface of the heat insulator, and then immediately attach it to the ceiling.

It is also worth paying attention to how

Warming the floor from below in a private house is a necessary measure to create a comfortable and warm environment. The main thing in this matter is to choose the right heat-insulating material. And although the choice today is very wide, you need to choose the insulation that will be convenient in terms of installation, fit your operating conditions and become reliable protection from heat loss.

Updated: 03.05.2019

In a wide range of floor insulation, foil material occupies a special place. Thanks to the reflective surface, the efficiency of the heat-insulating layer increases significantly, providing comfortable conditions in the home. Lightweight, durable, with good soundproofing properties, foil floor insulation is becoming increasingly popular in private housing construction, especially since its installation is not particularly difficult.

This insulation consists of two layers - a base and a reflective coating. As a basis, classic heat insulators are used - foamed polyethylene, expanded polystyrene, mineral wool and other materials. The reflective coating is a polypropylene metallized film or a thin layer of aluminum foil. The thickness of the insulation directly depends on the type of base.

Varieties of heaters

Foamed polyethylene insulation has a thickness of 2 to 10 mm and is available in rolls. It is usually used during the installation of a "warm floor", with further pouring of the screed, and as an insulating substrate for some types of floor coverings. Especially popular is self-adhesive material, the laying of which takes a minimum of time. The insulation has many varieties, of which the most popular are Isolon, Ecofol, Folgoizol, Penofol and Isoflex.

fiberglass insulation and mineral wool has a thickness of 50 to 100 mm, is commercially available in the form of rolls and plates. It is used for insulation floors, thermal insulation of baths and saunas. Foil-coated basalt insulation has increased heat resistance, but has one drawback: it contains phenol, which is unsafe for human health. The most popular brands of insulation: Knauf, Rockwool, Parok, Izover.

A heat insulator based on expanded polystyrene is produced in the form of rigid plates covered with foil. It is used when laying a warm water floor, as well as for thermal insulation of surfaces subject to dampness and heavy loads. For the convenience of laying heating pipes, special red markings are applied to the foil coating.

Properties of heaters

Foil heat insulators have the following properties:

• high reflectivity;
• resistance to temperature changes;
• moisture resistance;
• excellent steam, hydro, sound and heat insulation performance;
• durability;
• light weight;
• ease of installation.

Floors with such a heater will never become damp, will not require treatment with protective agents, and will last much longer. Most foil heat insulators do not contain carcinogenic components, so they can be used in any room, in addition, they reflect radiation, which is now important.

The type of coverage matters a lot. Aluminum foil perfectly reflects heat, but is destroyed by alkalis in concrete, and metallized film is not susceptible to such exposure. That is why insulation with an aluminum layer is not used for concrete or cement screed. The thickness of the reflective layer is no less important: some manufacturers simply spray over the heat-insulating base, which significantly reduces the effectiveness of the insulation. The thinner the layer, the easier it is for heat radiation to pass through it.

Wooden floor insulation

For work you will need:

• insulation;
• scissors;
• metallized tape;
• roulette;
• grinder;
• antiseptic primer;
• putty.

For wood, self-adhesive insulation is best, but if you purchased a regular one, you can attach it to the surface with a construction stapler or double-sided tape.

Step 1 Carefully prepare the base: remove the skirting boards, remove debris and dust, treat the surface with a grinder or scraper. If there are gaps, you need to close them with putty.

Step 2. For greater preservation of wood, the floor is primed with an antiseptic compound.

Step 3. After the primer dries, the insulation roll is brought into the room and the required amount of material is measured. Cutting is performed with ordinary scissors. Lay out the heat insulator on the floor with the reflective layer up, remove the protective film and press the material to the surface.

Step 4. The next canvas is laid end-to-end to the first, trying not to leave gaps along the seam. In the same way, the remaining strips of insulation are laid, if necessary, making cutouts for communications or niches.

Step 5. All seams between the strips are sealed with foil tape.

Step 6. Laying the top coat - laminate, parquet, linoleum.

concrete floor insulation

To attach the insulation to the concrete base, a special rubber-based adhesive is used. In all other respects, the technology is similar to the insulation of a wooden surface.

Step 1. concrete base carefully level, close up defects, clean the surface of dust.

Step 2 Roll out a roll on the floor, starting from the wall. Take measurements and cut off the excess with scissors. Next, the insulation strip is shifted to the side and glue is applied to the base. After 1-3 minutes, a foil insulation is laid on the floor and pressed. The reflective layer should be at the top. The use of glue is optional and many builders do not use it. Just like that, the insulation will not slide on the base and move during the laying of the finishing layer.

Step 3. The second and subsequent strips are laid end-to-end, the seams are fixed with adhesive tape. Now you can start laying the finish coating. Linoleum cannot be used as a coating, because the insulating substrate is soft, and linoleum will be squeezed under the weight of the furniture.

If the floors are very cold, after laying the foil material, logs are mounted from a bar, set them horizontally, the space between the logs is filled with ordinary insulation, and plank floors or sheet material are mounted on top.

Step 1. Floor slabs are thoroughly cleaned and irregularities are eliminated with putty or cement mortar.

Step 2. Roll reflective thermal insulation is laid, tightly joining the material. Glue all joints with metallized tape.

Step 3. A heating cable or heating pipes are laid out over the insulation according to the project.

Step 4. A thin film of polyethylene is laid over the heating elements, which will protect the foil coating from the aggressive effects of the cement screed.

Step 5 Knead the solution and pour the leveling screed. When the surface is dry, you can lay the final floor.

Laying slab material

Reflective thermal insulation in slabs is mounted mainly under underfloor heating, although it can also be used as a conventional insulation. With foil mats, a floating screed is made and laid between the lags.

floating screed

Step 1. The concrete surface of the floor slabs is leveled with the help of grinding. Cleaned from dust.

Kermi damper tapes

Step 4. Plates are taken with a metallized coating, since aluminum is corroded by cement. Glue is applied pointwise to the base of the mats, after which the insulation is laid on the floor with the reflective layer up. When laying the insulation, the joints are carefully adjusted so that gaps do not form.

Step 5. The joints are glued with adhesive tape, and then the heat-insulating layer is poured with a screed solution. Level the mixture with a wide spatula or rule and leave to dry. After that, you can perform the laying of the final coating.

Warming along the lags

Step 1 Remove the floor covering, clean the base from debris, check the integrity of the lag, and, if necessary, repair the damaged elements.

Step 2. A waterproofing material is laid on top of the logs and fixed with a stapler with inside bars, spreading the film well on the floor. The edges of the canvases overlap by 10-15 cm.

Step 3. The space between the lags is filled with foil plates, laying them in one or two layers. The plates of the second layer must necessarily overlap the seams of the lower layer. A gap of 1.5-2 cm is left between the reflective coating and the upper edge of the log. If the gap cannot be left, a crate of 20x40 mm slats is stuffed on top of the logs.

Step 4. Further actions depend on the type of flooring. If it is linoleum or laminate, the rough base is covered with sheet material - plywood, chipboard, OSB. If the floor is made of boards, they are stuffed directly onto the logs.
