Alufom foil insulation. Alufom - foil polyethylene foam. Sealing gaps with aluminum tape

Largest part Heat loss in buildings is due to infrared radiation. In this regard, massive materials ( basalt wool, penoplex, etc.) are not able to give the maximum level of 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 heat 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:

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

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

• Another major advantage this insulation- absolute moisture resistance. The aluminum layer is not "afraid" even of direct water ingress, which provides the material with a long operational period.
• Due to its properties, Alufom can also serve as sound and waterproofing. Laying two layers will completely solve the problem with finishing floors.
• High temperature resistance. The operating temperature range is quite high, thanks to which it can be used in all regions, even in the coldest ones.
• Space saving. The thickness of the insulation does not exceed 5 mm, which significantly reduces the cost of usable area when creating a heat-insulating layer.
• Ease of installation. 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 fixed to the original surface.

Are there any significant disadvantages of this heater? The only serious disadvantage of this material is the relatively high price. It is possible to organize 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 a heater, first of all, pay attention to the technical characteristics, since its effectiveness will depend on them. Next, consider the main indicators that affect the overall efficiency.

All available classifications

There are several varieties of Alufom insulation, differing in their key technical specifications:

• Alufom A is polyethylene foam, on one side covered with aluminum sprayed 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 against heat loss.
• B - is a polyethylene foam coated on both sides with aluminum foil. These are already more advanced models with a maximum operational period. Most often used for finishing roofs, attics, attics, etc.

Important! When buying, ask the seller for certificates of conformity. Today, often under the guise of popular materials, they sell cheap, partly "handicraft" counterparts. This is especially true for the sphere of foil insulation, in which the population did not have time to fully understand.

• C is a highly flexible polyethylene, which is covered with aluminum coating on one side, and on the other side with an adhesive core. This greatly facilitates the installation of the material, since it is unnecessary to take self-adhesive and additional fixing measures. Most often, this variety is used for arranging air outlets and heating mains (in combination with kaolin)

Application area

As mentioned earlier, Alufom has found wide application in many industries. It happened thanks to him high efficiency, which most competitors cannot boast of. Use it 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. At the same time, both external and internal insulation are acceptable (in the second case, the efficiency will be several times higher).
• Water mains. In this case, group B is used.
• Heating boilers, underfloor heating. This is achieved through a wide operating temperature range. Not many competitors are able to withstand such enormous loads (daily drops up to 400 degrees)
• transport objects. In particular, even more often than others, they are 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 the high cost, it can only be recommended 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.

ALUFOM reflective insulation is a complex heat, steam and sound insulation with a high coefficient of reflection of radiated thermal energy.

Polished aluminum foil (ALUFOM AL) or metallized polypropylene film (ALUFOM PE) is used as a reflective element (“thermal mirror”). Foamed polyethylene NPE is used as a basis.
The overall efficiency of the thermal insulation system with the use of ALUFOM reflective insulation increases by 20-70% (depending on particular conditions, seasons, etc.).

Alufom installation
Reflective thermal insulation ALUFOM AL is mounted directly on the wall and ceiling of the steam room of the bath or sauna with a reflective coating inside the room. If necessary, the front door is insulated. Installation is carried out using construction stapler or small nails. Cloths should be installed "end-to-end", connecting the joints with aluminum tape. A prerequisite The effective action of this insulation is the presence of an air gap of at least 9-15 mm from the surface of the foil to the nearest surface.
Aluminum is a good conductor, so electrical wiring must be well protected.
Mounted on a reflective coating wooden crate, on which the interior trim is mounted (lining, etc.)
Reflective thermal insulation ALUFOM RE is laid on the surface of the floor slab with the reflective coating facing upwards. Cloths should be installed "end-to-end", connecting the joints with metallized adhesive tape to create complete vapor and waterproofing. Mounted on a reflective coating heating elements while insulating the contacts to avoid short circuits. Then the entire surface is filled with monolithic cement-sand screed(thickness 4-6 cm). At the same time, additional protection for the reflective coating is not required, since it is made of a polymeric metallized film and is able to maintain its properties in the alkaline environment of the cement-sand mortar.

Reducing heat loss is one of the main tasks of both a private trader building his house and any other homeowner. Only correct selection hydro, heat and soundproof materials is able to guarantee in the future (after the completion of construction or repairs) the presence of a fairly comfortable indoor microclimate. Therefore, on the pages of this article of the site site, we will talk about innovative building material Alufom - with reflective insulation to reduce heat loss.

Scope of application

Alufom for arranging underfloor heating

Alufom is used quite widely, today it is used for thermal insulation of various packages, in thermal blankets, sleeping bags, in tent flooring, in construction, in transport (blinds, awnings), etc., however, Alufom is widely used in construction. It is mainly used to reduce heat loss;

Thermal insulation of the balcony with the help of Alufoma

• walls (from the outside, inside);
• in agricultural buildings;
• roofs;
• climatic equipment;
• when arranging underfloor heating;
• ventilation;
• boilers, heating appliances;
• pipelines;
• metal structures.

In addition, alufom is used in the transport industry in containers, vans, they protect bodies and engine compartments.

Application features

Since most of the heat loss occurs due to infrared radiation (this is about 60-65%), therefore massive thermal insulation materials don't provide enough good protection houses from heat loss. The main material that is able to return infrared rays back is aluminum foil. The walls of the building, which have such protection, return heat to the interior of the building in winter, and reflect heat radiation to the outside during the summer heat.

As already mentioned above, this is an innovative sound, hydro, heat insulating material that has a fairly high coefficient of heat reflection. The functionality of Alufom is based mainly on the properties of the polished foil with a high aluminum content and the presence of air bubbles in the polyethylene microfoam. Such a structure is capable of reflecting up to 97 percent of heat radiation in the summer and preventing cooling in the winter.

Alufom is used to insulate the pipeline

Advantages

Alufom has a lot of advantages over similar materials. If you look at the reviews, then with it you can equip the most reliable and high-quality thermal protection. It also creates hydro, steam, and sound insulation and is able to function reliably even in conditions high humidity. When using it, it saves usable space, so it has a small thickness, in addition to everything during operation, it does not wear out, does not rot and is environmentally friendly. To work with it is not required, any (overalls), the installation of this material is quite simple, since it has a low weight. It has no significant shortcomings.

Alufom on a self-adhesive basis

Varieties of material

Alufom, depending on the available technical characteristics, can be divided into varieties, such as Alufom A, Alufom B, Alufom C.

1. Alufom A- made on a polyethylene basis, which on the one hand has a foil coating. It can be used as a vapor barrier or an additional layer of thermal insulation, and sometimes it is laid in two layers. In this case, Alufom is able to provide full heat and waterproofing.
2. Alufom B- made of polyethylene and coated on both sides with foil. Use it for arranging roofs, insulation attic rooms, gender, etc.
3. Alufom S(on a self-adhesive basis) - polyethylene is covered with foil on one side, and its other side is covered with glue, and on top of the glue with a special coating material. This type of Alyufoma is mainly used only on air outlets.

The problem of reducing heat loss today confronts every owner of real estate (the state, the subject of the federation, legal and individuals). Right choice thermal insulation of buildings is the most important condition for creating a comfortable indoor microclimate, slowing down the destruction of walls from thermal stress and humidity, and reducing the cost of consumed energy resources (gas, electricity, solid and liquid fuels).

A serious task is to improve the heat-shielding properties of existing buildings. This problem can be solved according to new requirements, only due to the device of additional thermal insulation, performed from the most effective materials, providing long-term preservation of quality indicators during operation and environmental friendliness.

It is known that heat is transferred in three ways: thermal 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 the 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 up and are replaced by cold ones.

Radiation is the propagation of electromagnetic waves in space. When the body absorbs such rays, their energy turns into heat, heatsit and passes it on, entering into molecular contact with solid and liquid bodies. Manufacturers of massive insulating materials, payingattention to the meaningR, lose the 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 like batteries that store heat, which is then radiated again. A vivid 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 why in the summer at noon it is quite hot in buildings that are not provided with air conditioning, but have massive insulation. Fighting this phenomenon requires additional energy costs. When heating massive insulation in cold weather, condensate will form and, as a result, the penetration of water vapor into constituent elements walls. When moistened, heat insulators made on the basis of mineral wool and glass wool lose their insulating properties up to 50%. According to their technical characteristics, not all heat insulators can be used in a residential area. The main material used to stop losses from thermal radiation is polished aluminum foil with a high degree of pure aluminum content. The use of foil makes it possible to reflect heat radiation back to its source. Therefore, the building on a hot summer day will be protected by the reflection of thermal radiation to the outside, and in winter by the reflection of expensive heat inward. All this contributes to a more efficient use of heat and energy resources.

One of the most effective types heat, steam, and sound insulation is ALUFOM ( PENOFOL ) - reflective thermal insulation material of the new generation, reducing by 70% heat loss 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 in polyethylene do not start.

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

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

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

insulation ALUFOM designed for heat, noise, and vapor barriers of building envelopes, thermal insulation of air ducts and pipelines of cold and hot water supply systems and heating systems for rooms B, G, D in residential, public and industrial buildings, including agricultural, isolation of buildings and structures from radon, for isolation of transport containers, cars, tents, 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 wrap or use specially produced laminated ALUFOM (PENOFOL). Aluminum is a good conductor - electrical wiring must be reliably protected! A simple installation of Alufoma behind a heating radiator increases its efficiency by 20-30%. ALUFOM (PENOFOL) can be used for waterproofing wooden structures buildings. To insulate the external walls inside the room with ALUFOM, foiled on 2 sides (type B), a crate is made on the wall, on which it is stuffed with a stapler or nails into the joint with obligatory gluing with foil tape to ensure vapor barrier.

With a brickwork thickness of 1-n brick R = 0.5, in this case you can add between brickwork and foam up to 50 mm of mineral wool insulation into the first crate, which will give R \u003d 0.5 and as a result we get 2.72, etc. The use of ALUFOMA (PENOFOL) for wall insulation increases usable area on 4 linear meters by 0.2 - 0.4 square meters. When installing walls, roofs, it is necessary to provide ventilation from the side of the foil. ALUFOM can be used as floor insulation, baths, toilets. concrete screed, fill the mesh and also put concrete, and on top tiled flooring. For floor insulation ALUFOM can be placed under the carpet. By insulating pipes, you can save on the thickness of the insulating layer and prevent rust. For effective pipe insulation, ALUFOM (PENOFOL) with 2-sided foiling is used.

To create an air space between the pipe and the foil, bandage rings made of ALUFOM or other material with a height of at least 20 mm are placed on the pipe, then the pipe is covered with ALUFOM. For insulation 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 the roofs in summer, ALUFOM with double-sided foiling can be used (heating of the roof in summer is more than 80 ° C).

All seams must be sealed with aluminum tape to create a heat and vapor barrier. Aluminum tape is used to repair damaged ALUFOMA foil.

The latest thermal insulation materials help to significantly reduce the cost of space heating. Wall cladding with foil insulation - economical solution for homeowners who are ready to carry out the installation of thermal insulation on their own.

Features of foil material

Combined insulation includes two main components: heat-insulating material, foil. The aluminum coating provides the main quality property of the insulation: reflective thermal insulation with an effect of 97%. In addition to thermal insulation, the main advantage, the material is characterized by properties:

• elasticity;
• soundproofing;
• water resistance;
• environmental friendliness.

Combined insulation

The foil product has a long service life without loss quality characteristics, does not undergo decomposition, deformation. Manufacturers indicate a service life of up to 95 years. Light weight and layer thickness are convenient for transportation, installation, do not take up living space during interior decoration apartments, allow you to model structures when finishing curly elements. Cope with the installation of foil panels, plates can even be inexperienced in construction work human.

For external walls buildings finished with foil insulation - reliable protection from the adverse effects of climatic factors: wind, severe frost, high humidity, temperature changes. The heat resistance of the material is combined with resistance to solar and radon radiation. An important factor is the interaction of the heat insulator with different facing materials.

Types of foil insulation

Products are produced from different indicators density of the foil layer, types of heat-insulating base.

Penofol

Universal insulator (second name: isolon, ecofol) based on polyethylene foam. Foil coating is allowed both one-sided and two-sided. One of the types of product is a self-adhesive sheet with an adhesive layer under a protective film - the installation of a heat insulator is greatly facilitated. Supplied foam rolls. Some types of material are reinforced in the structure with fiberglass reinforcing mesh. Penofol is known as an environmentally friendly and safe heat insulator.

Penofol foil self-adhesive

Layer thickness 3-8 mm. Thermal conductivity 0.038 W / (mK), moisture absorption in the range of 0.35-0.7%. The vapor permeability of the material is 0.001 mg / m * k.

Penofol is fixed on the walls behind the batteries central heating to keep warm air through reflective thermal insulation. The free space between the wall and the battery is recommended to be kept at about 2 cm. The material serves not only as a sheathing internal walls premises. Foil penofol trim the floor, roofs, insulate pipes. The high water resistance of the insulation with foil justifies the use in the construction of saunas.

The cost of a roll of penofol is affected by the thickness of the heat-insulating base of the insulation.

Foil mineral wool

The product is produced in the form of plates, mats, rolls with an insulating layer thickness of 5-10 cm. Foil coating is present only on one side.

In the role of insulation, fiberglass, stone basalt wool is used. The use of the second material is limited exterior trim walls of buildings or use in non-residential buildings. The reason lies in the release of phenol dangerous to human health. Additional insulation of foil boards with a protective film is carried out where increased resistance to high temperatures is required.

According to the technical characteristics, basalt wool can withstand temperature fluctuations from -200 to +300°C. Thermal conductivity up to 0.07 W/(mK). Aluminum protection provides hygroscopic material from high humidity. Products differ in the increased durability, do not attract rodents, are not subject to fungal infections. Important factor- resistance to ignition, so the material is often used for sheathing wooden buildings, baths. Long term operation allows the use of basalt insulation in non-residential buildings with an aggressive environment.

Fiberglass wool with a waterproofing foil layer is often used in internal thermal insulation walls of saunas, showers.

Styrofoam

A foil product based on the fusion of polystyrene granules is in demand by the "warm floor" system. The markup made by the manufacturer is intended for the cable system. The thickness of the material is 3-5 mm. Thermal conductivity indicators do not exceed 0.035 W / m2, density - up to 45 kg / m3.

Foil insulation for underfloor heating

Increased strength ensures safe use in places with mechanical loads, with high humidity. Retains properties in the temperature range from -180° to +180°C.

The use of foil insulation

Thermal insulation materials with foil coating are compatible with almost any surface. Subject to properties different types insulation, most often, walls with internal and outside, verandas, floor, entrance doors, balconies of various buildings.

• for floor insulation - solid polystyrene foam boards;
• for saunas, baths - mineral wool with high vapor barrier;
• for walls, doors, ceiling - insulation based on foamed polyethylene.

It is easier to carry out thermal insulation of the surface of walls, partitions behind heating devices, batteries with self-adhesive material.

Rules for installing foil insulation

The peculiarity of the installation of foil insulation is that the shiny side with metal coated should always be directed towards the inside of the room. Incorrect setting will result in loss of reflection effect, i.e. decrease in thermal insulation.

Between finishing walls and a layer of foil insulation, it is recommended to keep an air gap of up to 1.5 cm for additional thermal protection, the effect of a thermos.

A home master for installing a heater will need:

• nails with a large hat;
• hammer and nail puller;
• construction tape;
• acrylic or rubber glue;
• construction stapler.

You can cope with the work alone, but the installation together, with an assistant, will go faster.

Sealing gaps with aluminum tape

Insulation of walls inside the room

The main stages of laying insulation:

1. Wall preparation. Insulation of walls with old wallpaper from the inside requires preliminary cleaning, coating with an antiseptic.
2. Fixing the heater. It is allowed to stick rolled sheets on the wall or to build a crate, in the cells of which the plates are attached. The first mounting option is more common.
3. Additional fixation of the insulation with a construction stapler or nails.
4. Treatment of cracks with aluminum tape.
5. Fixing the slats to create an air gap before the final cladding.

Thermal insulation of the basement with foil insulation from the inside

When installing insulation inside a room, at home, you should consider:

• mineral wool laying should be in dense rows without gaps between the plates;
• material foiled on both sides needs two air pockets - from the outer wall, from the finish;
• sheets of roll insulation are never overlapped on each other;
• fastening of self-adhesive mineral wool with a foil layer must be reinforced with nails around the perimeter to reduce the risk of delamination.

Garage insulation from the inside

If the room is completely covered with insulation, then work should begin from the ceiling, then go to the walls, lay the floor insulation - last.

Wall insulation from the outside

Warming the walls from the inside is preferable, as it allows you to better retain heat. If for some reason this is not possible, then heat-insulating materials are mounted outside. Experts recommend using foil-clad mineral wool.

The master will need to carry out the work the following materials and tools:

• mineral wool of medium thickness with a foil layer;
• glue;
• construction pistol;
• brush;
• windproof film;
• dowels.

Wall insulation from the outside

Insulation of the outer wall is the formation of a “layer cake” in a certain way with a filling in the form of a heat insulator - foil mineral wool. Work is carried out in stages:

1. Creation of a metal crate for the location of plates of heat-insulating material. The structure is attached to concrete or wooden wall buildings with dowels. Choice metal frame more reliable than wood, as the cladding will be resistant to deformation when exposed to different temperatures and humidity.
2. Fixing the insulation on the crate with gluing to the wall. On the reverse side plates of foil mineral wool, it is required to apply a point adhesive mass, press it against the wall. Dowels can be additional fasteners.
3. Leveling the surface with a sanding brush.
4. Anchoring windproof film, waterproofing. Fixation is carried out with a construction stapler, small nails with large caps.

Warming brick house outside

It should be noted that the construction of a metal crate made of a galvanized profile should take into account the width of the panels, heat insulator plates, in order to reduce the number of joints.

Finishing is mounted, as a rule, on an additional subsystem while maintaining the ventilation gap.

Sheathing of the external walls of wooden structures can be made with foil penofol. The material is lighter, the cost of insulation is lower. It is recommended to choose a perforated type of penofol to enhance the protection against getting wet walls.

Before direct installation of the insulation, the walls must be treated with an antiseptic, paying special attention to the corners of the house. The joints of foam sheets are recommended to be glued with metal tape. The crate can be wooden. The work is carried out in the same order as when installing mineral wool.

It is important to consider that the insulation of the external walls of the house is carried out exclusively in dry weather at a positive air temperature.

The use of foil insulation enhances the effect of maintaining a comfortable indoor environment. Experts recommend taking this factor into account when making decisions on the choice of thermal insulation material.
