Reducing heat loss is the main task of every homeowner, both private owners and legal entity. Only right choice heat, hydro and sound insulation can guarantee the presence of a comfortable microclimate inside the building. In this article we will consider Alufom reflective insulation.
Features of Alufoma
Since the main share of heat loss comes from infrared radiation (about 65%), massive insulating materials cannot completely protect the house. The main material that is able to return the rays back to the source is foil containing a high proportion of aluminum. The walls of the building having such protection, in summer heat will reflect thermal radiation outward, and in winter - heat inward.
Alufom - innovative hydro-, sound-, thermal insulation, which has high coefficient heat reflection. Its functionality is based on the properties of polished foil with a high aluminum content and air bubbles inside polyethylene microfoam. This structural feature of the material is clearly visible in the photo. Aluf insulation can reflect about 97% of radiated heat, preventing the room from heating up in summer and cooling in winter.
Scope of application
Today, the use of Alufom knows no bounds. It is used in construction, transport, in greenhouses (awnings, blinds), in thermal insulation packaging, in sleeping bags, thermal blankets, and in tent flooring. This material is most widely used in construction. It is used in the following cases:
- roofs;
- under heated floors;
- walls (inside, outside);
- climatic equipment;
- ventilation;
- pipelines;
- heating appliances, boilers;
- metal structures;
- country houses;
- agricultural buildings;
- saunas.
In the transport industry, Aluf insulation is indispensable in vans and containers; it is excellent for protecting engines and bodies.
Technical characteristics of Alufoma
Types of material
Depending on the technical characteristics, Alufom is divided into several varieties. Aluf A- This is polyethylene foam, which has a one-sided foil coating. Can be used as a vapor barrier or as an additional layer of thermal insulation. This insulation is sometimes placed in 2 layers. Then it is able to provide water protection and complete thermal protection. Alufom V- polyethylene foam covered with foil on both sides. Alufom S- a material based on polyethylene foam, which is covered on one side with foil, and on the other with glue and a special coating material. This type is mainly used on air vents.
Advantages of Aluf insulation
This material has many advantages over its analogues. According to reviews, with the help of Alufom you can provide the most reliable thermal protection. In addition, it creates sound insulation, vapor and waterproofing, and provides protection against radon. It is able to function reliably when high humidity. It has no significant disadvantages. Using Alufom saves money usable space, because the material is thin. In addition, it does not rot, does not wear out, and is environmentally friendly. It is installed quite simply; no special clothing is needed. This lightweight material, which is available for transportation and installation.

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 provide 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 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 bulky 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.
- Another important advantage this insulation- absolute moisture resistance. The aluminum layer is not “afraid” of even direct contact with 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
When choosing insulation, the most experienced craftsmen first of all pay attention to specifications, since its effectiveness will depend on them. Next, we will consider the main indicators that affect the overall efficiency.
| Technical specifications | Material type | ||
| A | IN | WITH | |
| Thermal reflection coefficient (from) | 0,9 | ||
| Optical reflectance (from) | 97 | ||
| Thermal conductivity index (at normal conditions), W/m*S | 0,031 | 0,032 | 0,033 |
| Specific gravity (for models standard thickness) kg/m2 | 0,15-0,22 | 0,17-0,24 | |

| Elasticity index (dynamic) MPa | 0,26 | 0,39 | |
| Heat absorption rate (per day) | 0,51 | 0,45 | |
| Specific heat capacity m2*C/W | 1,95 | ||
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 maximum operational period. Most often used for finishing roofs, attics, 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 yet fully understood.
- 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 there is no need to take additional measures for fixation. Most often, this variety is used for arranging air vents and heating lines (in combination with kaolin)
Application area
As mentioned earlier, Alufom has found wide application in many industries. This happened due to its 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.
Description
Reflective insulation ALUFOM - a trademark of the Resurs company - is a comprehensive 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 base.
Overall efficiency thermal insulation system with the use of reflective insulation ALUFOM increases by 20-70% (depending on individual conditions, seasons, etc.).
Properties
Installation of Alufoma
Reflective thermal insulation ALUFOM AL mounted directly on the wall and ceiling of the steam room of a bathhouse or sauna with a reflective coating inside the room. Insulated if necessary Entrance door. Installation is carried out using a construction stapler or small nails. The panels should be installed end-to-end, connecting the joints with aluminum tape. Required condition effective action 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 - good guide, so the electrical wiring must be reliably protected.
Mounted on reflective coating wooden sheathing, on which it is mounted interior decoration(lining, etc.)
Reflective thermal insulation ALUFOM RE laid on the surface of the floor slab with the reflective coating facing up. The panels should be installed end-to-end, connecting the joints with metallized tape to create complete vapor and waterproofing. Mounted on a reflective coating heating elements, in this case the contacts should be insulated to avoid short circuit. Then the entire surface is filled with monolithic cement-sand screed(4-6 cm thick). Wherein additional protection for a reflective coating is not required, since it is made of a metallized polymer film and is able to retain its properties in the alkaline environment of a cement-sand mortar.

Reducing heat loss is one of the main tasks of both a private owner building his own house and any other homeowner. Only correct selection hydro, heat and soundproofing materials is able to guarantee in the future (after completion of construction or repairs) the presence of a fairly comfortable indoor microclimate. Therefore, on the pages of this article on the site we will talk about innovative building material Aluf - has reflective insulation to reduce heat loss.
Scope of application
Alufom for arrangement of heated floors Alufom is used quite widely, today it is used for thermal insulation of various packages, in thermal blankets, in sleeping bags, in tent flooring, in construction, in transport (blinds, awnings), etc., but Alufom is used quite widely in construction. It is used mainly to reduce heat loss;
Insulating a balcony with Alufoma - in saunas;
- in country houses;
- walls (outside, inside);
- in agricultural buildings;
- roofs;
- climatic equipment;
- when installing heated floors;
- ventilation;
- boilers, heating devices;
- pipelines;
- metal structures.
Insulation of the engine compartment in a car using Alufoma
In addition, Aluf is used in the transport industry in containers and vans to protect bodies and engine compartments.
Features of application
Since most of the heat loss occurs due to infrared radiation (this is approximately 60-65%), therefore, massive thermal insulation materials do not provide enough good protection home from heat loss. The main material that can return infrared rays back is aluminum foil. The walls of the building, which have such protection, return heat to the inside of the building in winter, and in the summer heat they reflect thermal radiation outside.
As mentioned above, this is an innovative sound, hydro, thermal insulation material, which has a fairly high coefficient of heat reflection. The functionality of Alufom is based mainly on the properties of polished foil with a high aluminum content and the presence of air bubbles in polyethylene microfoam. Such a structure is capable of reflecting up to 97 percent of heat radiation in summer time and preventing cooling in winter.
Aluf is used for pipeline insulation Advantages
Alufom has many advantages over similar materials. If you look at the reviews, you can use it to create 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 of high humidity. When used, it saves usable space, as it has a small thickness; in addition, during operation it does not wear out, does not rot, and is environmentally friendly. To work with it, you do not need any special clothing; installation of this material is quite simple, since it is light in weight. It has no significant disadvantages.
Alufom on a self-adhesive basis Types of material
Alufom, depending on the available technical characteristics, can be divided into varieties, such as Alufom A, Alufom B, Alufom S.
- Aluf A– made on a polyethylene base, which is coated with foil on one side. It can be used as a vapor barrier or as an additional layer of thermal insulation, and sometimes it is laid in two layers. In this case, Alufom is able to provide complete warmth and waterproofing.
- Alufom B– made of polyethylene and covered on both sides with foil. It is used for roofing and insulation attic rooms, floor, etc.
- 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 Alufoma is used mainly only on air vents.

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 look this is with foil and foam rubber.
How much does this material cost? 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, you can also use special rubber-based glue; the joints of the sheet are glued with tape. If we are talking about insulating a 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 there its maximum loss occurs. 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 compliance with the 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 ones for chimneys of 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 similar works 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 To ensure everything dries well, treat the lower part of the building especially carefully. 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:
