Aluf foil wall insulation. Alufom - reflective insulation to reduce heat loss. Technical characteristics of Alufoma

The problem of reducing heat loss today faces every property owner (state, federal subject, legal and individuals). Right choice thermal insulation of buildings is the most important condition to create a comfortable indoor microclimate, slow down the process of destruction of walls from thermal stress and humidity and reduce payments for consumed energy resources (gas, electricity, solid and liquid fuels).

A major challenge is to improve the thermal insulation properties of existing buildings. This problem can be solved according to new requirements, only due to the installation of additional thermal insulation, carried out from the most effective materials, ensuring long-term preservation of quality indicators during operation and environmental cleanliness.

It is known that heat is transferred in three ways: conduction, convection and infrared radiation. Pictures show the share of these components in the total heat transfer for an empty building without internal partitions:

As can be seen from the figures, the dominant role in all cases is played by thermal radiation.

Heat transfer - this is the movement of heat at the molecular level (when one end of a rod is heated, the other end of the rod is heated due to heat transfer).

Convection - is the movement of heat through gases and liquids due to their movement. Warm masses rise upward and are replaced by cold ones.

Radiation - this is distribution electromagnetic waves in space. When a body absorbs such rays, their energy turns into heat, heatingand passes it on, coming into molecular contact with solid and liquid bodies. Manufacturers of massive insulating materials, reversingattention to the meaning of "R", lose insulation of the largest source of thermal energy - thermal radiation. Modern massiveinsulating materials, despite their thickness, do not have the ability to reflect thermal radiation. In fact, they act as batteries that accumulate heat, which is then emitted again. A clear confirmation of this is any building in the evening after a hot day. Even with open windows and doors the building remains “hot”. This is the main reason that in the summer at noon in buildings that are not provided with air conditioning, but have massive insulation, it is quite hot. Combating this phenomenon requires additional energy expenditure. When massive insulation is heated in cold weather, condensation will form and, as a result, water vapor will penetrate into the constituent elements of the wall. When humidified, heat insulators made on the basis mineral wool and glass wool lose their insulating properties up to 50%. Due to their technical characteristics, not all heat insulators can be used in residential premises. The main material used to stop losses from thermal radiation is polished aluminum foil with high degree pure aluminum content. The use of foil allows thermal radiation to be reflected back to its source. Therefore, the building will be protected on a hot summer day by reflecting thermal radiation outward, and in winter by reflecting expensive heat inward. All this contributes to more effective use thermal and energy resources.

One of the most effective types heat, steam, and sound insulation is ALUFOM ( PENOFOL ) - reflective thermal insulation material new generation, reducing by 70% heat losses in the building in winter and heat accumulation in summer, reflecting 97% of thermal radiation, creating a “thermos effect”, environmentally friendly - completely harmless to humans, fireproof. You can walk on the insulation - the material can withstand human weight without changing its structure. Retains its properties when wet. Rodents and insects cannot grow in polyethylene.

ALUFOM (PENOFOL) is multilayer material, consisting of a layer of environmentally friendly food grade polyethylene foam with low thermal conductivity, on one side (type A) or on 2 sides (type B) covered with clean (99.4%) food foil with high reflective characteristics. Type C is produced with one-sided foil, on the other side an adhesive composition with a coating material is applied. The foam can be from 2 to 8 mm thick in rolls up to 30 meters long. Has unique thermal insulation properties at low thickness.

ALUFOM(PENOFOL) increases the heat-protective properties of structures without increasing volume and is used as an independent thermal and sound insulation, or together with various types insulation, significantly complementing their properties, provides a comfortable microclimate in residential and other premises.

ALUFOM installed under the roof of agricultural buildings will relieve domestic animals from the sweltering heat in summer and soften frost in winter, which will immediately affect growth and milk yield.

Fire technical characteristics:

Insulation ALUFOM designed for heat, noise, and vapor insulation of building envelopes, thermal insulation of air ducts and pipelines of cold and hot water supply systems and heating systems for premises B, D, D in residential, public and industrial buildings, including agricultural, insulating buildings and structures from radon, for insulating transport containers, cars, awnings, tents, field hospitals, sleeping bags, etc.

Installation:

The maximum effect of the material is ensured when there is an air space of at least 1-2 cm on the side of the ALUFOMA foil. In a wet screed, cement and its components are an aggressive environment for the foil, so it is necessary to protect the foil plastic film or use specially produced laminated ALUFOM (PENOFOL). Aluminum good guide- electrical wiring must be reliably protected! A simple installation of Alufom behind a heating radiator increases its operating efficiency by 20-30%. ALUFOM (PENOFOL) can be used for waterproofing wooden structures buildings. To insulate external walls indoors with ALYUFOM, foil-coated on both sides (type B), a lath is made on the wall, onto which it is stapled or nailed into the joint, with obligatory gluing with foil tape to ensure vapor barrier.

With a brickwork thickness of 1 brick R=0.5, in this case you can add between brickwork and foam up to 50 mm mineral wool insulation into the first sheathing, which will give R=0.5 and as a result we get 2.72, etc. The use of ALUFOMA (PENOFOL) for wall insulation increases the usable area by 4 linear meters by 0.2 - 0.4 square meters. When installing walls and roofs, it is necessary to provide ventilation from the foil side. ALUFOM can be used to insulate floors, bathtubs, and toilets and can be placed on it concrete screed, fill the mesh and also put concrete, and on top tile covering. To insulate the floor, ALUFOM can be placed under the carpet. When insulating pipes, you can save on the thickness of the insulating layer and prevent rust. For effective pipe insulation, ALUFOM (PENOFOL) with 2-sided foil is used.

To create an air space between the pipe and the foil, bandage rings made of ALUFOMA or other material with a height of at least 20 mm are placed on the pipe, then the pipe is covered with ALUFOMA. To insulate ventilation ducts and pipes, it is most effective to use self-adhesive ALUFOM (PENOFOL) type C. When insulating ceilings, roofs and attics, reflective insulation significantly increases the heat-shielding properties of the structure without increasing its volume.

To avoid the penetration of radiation through roofs in summer, you can use ALUFOM with double-sided foil (roof heating in summer is more than 80 °C).

All seams must be taped with aluminum tape to create a heat- and vapor-tight layer. Aluminum tape is used to repair damaged ALUFOMA foil.

Installation of foil insulation

Foil insulation has a fairly wide range of applications; it is used for insulating pipes with cold and hot water, for insulating walls, as a substrate when laying parquet or under laminate, for insulating hives, soundproofing a room, roofing works, insulation of ventilation ducts, thermal insulation of industrial equipment.

This insulation is used to line the walls from the inside of the room behind the radiators to reduce heat loss, since it is heat-resistant. Our market offers the following trade marks: Alufom, Ursa, Penofol, Folgoizol, Izolon, Knauf, Lavsan, Magnel, Megaflex, Penoplex, Ecoteplin, the most popular type is with foil and foam rubber.

What is the price this material? It all depends on the manufacturer you choose; the price ranges from $1 to $4 per meter2. Let's try to take a closer look at how to properly place this material on various surfaces.

On the wall

Often walls are insulated with similar material in baths, saunas, and balconies; in this case, polyethylene-based material is used. It is recommended to use insulation with a thickness of at least 10 mm; such material can be covered with foil on one side or on both sides.

If we consider the options on what it can be attached to, the best fit construction stapler, Double-sided tape, can also be used special glue on a rubber base, the joints of the sheet are taped with tape. If we're talking about about insulating the balcony, then you need to lay an additional thermal insulation layer, for example, polystyrene foam, basalt material or other.

Is it possible to insulate without them? Of course yes, however you will not get the desired result. In order for the insulation to fulfill its intended purpose, it is necessary to figure out how to install it correctly. The distance between the material and the sheathing should be approximately 20 mm, this will create a certain air gap, which will serve as an air barrier.

Let's take a closer look at how to properly mount it to the wall:

• Attach the foam to a previously prepared surface.
• on top of it secure the foil insulation.
• Then on top install wooden beams, then sew everything up with the selected material (gypsum, siding), and seal the joints with foil tape.

To the ceiling

As a rule, it is chosen for the ceiling maximum thickness insulation, since all the heat rises upward, and its maximum losses occur there. Thanks to its reflective surface, the insulation is able to reflect up to 90% of the heat, thus increasing the overall efficiency of the insulation system by 60%. These characteristics can be obtained subject to installation rules.

To carry out the work you will need the following:

• Construction stapler.
• Small nails.
• Hammer.
• Insulation material.
• Aluminum tape.

This product is sold in rolls; for ease of installation, cut it into the required lengths. Which side should you lay it on? Installation should be done so that the foil surface is indoors (with the silver side facing you). So, let's figure out how to nail this material.

Gap between finishing material and the insulation should be about 20 mm, this buffer zone protects the room from heat loss.

When attaching to the ceiling, secure it using a stapler; the fastening should be butt to end, and assembly seams glue with aluminum tape to ensure hydro- and thermal insulation.

On the floor

Perhaps the installation process on the floor is the most labor-intensive, and there are more possible variations, since you can lay a warm floor system (not just a water floor) under linoleum, parquet, laminate. All this is possible thanks to its non-flammable base, since there is reflective foil on one side and foam rubber on the other.

Some manufacturers have variations with foam on both sides. So, let us describe in more detail the process of installing a wooden floor. To do this we need the following: construction knife, insulation, aluminum tape, meter, grinding machine, antiseptic primer, putty.

For this type of work, it is better to give preference to a material with an adhesive backing, however, you can get out of the situation with double-sided tape.

Work order:

• Prepare the base, remove the baseboard, treat the floor grinder If there are any unevenness, remove them using putty.
• Treat with antiseptic liquid. After drying, take measurements and cut into the required pieces. Lay a sheet with foam inside and foil outside.
• Execute seam sealing using metallized tape.
• Then lay parquet, laminate.

If you are insulating a concrete floor, the technology is similar, however, it is better to use specialized rubber adhesive for gluing. But in all other respects the technology is the same. If you have a very cold floor, in such a case they stuff the insulation with wooden joists, the niches in them are filled insulation material, it is covered with sheets of OSB boards on top, then the selected coating material is primed and laid.

Types of material

Let's look at what types of insulation are called:

How to put insulation on pipes

As a rule, such material has the form of a pipe “cocoon” made of mineral wool (withstands high temperatures) or polystyrene foam (moisture resistant). How to insulate them, the question disappears in itself, since they have the appearance of a “cocoon”, which is put on top and fixed. There are main lines for chimneys, various diameters and temperature conditions.

However, if you decide to purchase sheet insulation, you may be faced with the question of how to glue it to metal? Aluminum tape will come to your aid, which is wound onto the insulation over the pipe. And, as in the options described above, you need to wear it with the shiny side facing you.

Is it possible to insulate the walls from the outside?

To insulate the walls from the outside, perforated foil insulation is used. This is a material that, among other things, has soundproofing qualities, can protect your home from moisture and wind, and also does not prevent moisture from leaving the room. This option is ideal for those who do not have the opportunity to perform such work indoors. However, such activities can only be carried out in the warm season and in dry weather.

To do this you will have to do the following:

• If you had any kind of covering on the wall, you need get rid of him. Then treat the surface with an antiseptic solution. It's better to do this in hot weather so that everything dries well, handle it especially carefully bottom part building. Within two days the surface will dry completely.
• Further build a frame from timber, secure it with self-tapping screws. Lay Penafol, then leave an air tunnel, glue the joints, then install the outer frame.

In conclusion, we suggest watching a video about the installation of Penofol thermal insulation:

The largest part of heat loss in buildings occurs due to infrared radiation. In this regard, massive materials ( basalt wool, penoplex, etc.) are not able to give maximum level thermal insulation. However, this problem has constructive solution- Aluf.

Alufom has a base made of aluminum foil, thanks to which it is able to reliably protect buildings. On hot days it reflects thermal radiation, and in winter it retains heat inside. Next, we will get acquainted with the main features of such thermal insulation.

Advantages and disadvantages

This type of thermal insulation has the following advantages:

• Highest heat reflection. In this aspect, foil models outperform bulk materials. Their efficiency is close to 100% (on average it is 97%), which practically eliminates the possibility of heat loss.

Advice: such thermal insulation is the best option for finishing baths.

• Other most important virtue this insulation- absolute moisture resistance. The aluminum layer is not “afraid” even direct hit water, which provides the material with a long service life.
• Due to its properties, Alufom can also serve as sound and waterproofing. Laying two layers will completely solve the problem of finishing the floors.
• High temperature resistance. The operating temperature range is quite high, making it suitable for use in all regions, even the coldest.
• Space saving. The thickness of the insulation does not exceed 5 mm, which significantly reduces costs usable area when creating a thermal insulation layer.
• Easy to install. Alufom is very light, which makes it easy to work with. There is no need to create any strength frames - the sheets can be immediately attached to the original surface.

Are there any significant disadvantages to this insulation? The only serious disadvantage of this material is the relatively high price. It is possible to create a high-quality insulating layer at a cost 1.5-2 times lower. However, it should be borne in mind that it provides sound and moisture protection, so there is no need to lay the appropriate layers.

Key Specifications

Most experienced craftsmen When choosing insulation, first of all, pay attention to the technical characteristics, since its effectiveness will depend on them. Next, we will consider the main indicators that affect the overall efficiency.

All available classifications

There are several types of Alufom insulation, differing in their key technical characteristics:

• Alufom A is polyethylene foam, coated on one side with aluminum spray foil. Most often used as a vapor barrier, or additional insulation. Laying in 2 (for cold layers 3) layers allows you to create reliable protection from heat loss.
• B - is polyethylene foam covered on both sides with aluminum foil. These are already more advanced models with a maximum service life. Most often used for finishing roofs, attic premises, attics, etc.

Important! When purchasing, ask the seller for certificates of conformity. Today, cheap, partly “handicraft” analogues are often sold under the guise of popular materials. This is especially true for the field of foil insulation, which the population has not had time to fully understand.

• C is a particularly flexible polyethylene, which is coated with aluminum coating on one side and adhesive base on the other. This greatly facilitates the installation of the material, since it is self-adhesive and additional measures there is no need to take any fixing steps. Most often, this variety is used for arranging air vents and heating lines (in combination with kaolin)

Application area

As mentioned earlier, Alufom found wide application in many industries. This happened thanks to him high efficiency, which most competitors cannot boast of. It is used for insulation:

• Roofs, attics and attics. Here, high moisture resistance comes to the fore.
• Saunas, baths, garages.
• Climate systems.
• Walls of private and industrial buildings. In this case, both external and internal insulation is permissible (in the second case, the efficiency will be many times higher).
• Water mains. IN in this case group B is used.
• Heating boilers, heated floors. This is achieved thanks to a wide range of operating temperatures. Not many competitors are able to withstand such colossal loads (daily changes of up to 400 degrees)
• Transport facilities. In particular, they are even more often used for finishing containers and vans. Its properties are ideal for these conditions.
• Country and agricultural buildings.

Conclusion

In general, Alufom seems to be an excellent material capable of solving many problems. However, given high cost, it can be recommended only in cases where there is very high humidity(baths, saunas, baths, etc.), or when design features do not allow the use of more massive materials.
