Reflective insulation Aluf

Reflective insulation Aluf Foil-clad Aluf - characteristics, photo

The greatest heat loss in buildings will occur due to infrared type of radiation. In this regard, materials of a massive type (for example, the same penoplex, basalt wool, etc.) are not able to provide the maximum level of thermal insulation. however, this problem has certain constructive solutions - reflective insulation by Aluf.

Study of the features of the material.

This type of material, like Alufom, has a foil-clad aluminum base, and due to which it can perfectly protect the building.

On days when the heat is unbearable, it is able to reflect heat radiation, and in the winter season, it perfectly retains heat from the inside. Next, we suggest that you familiarize yourself with the main features of this thermal insulation.

General information. Advantages and Disadvantages

This type of thermal insulation has the following advantages:

Highest thermal reflection.

In this aspect, models of the foil type are more than able to outperform bulk materials. Their efficiency is about 100% (on average, this indicator is 97%), and this will almost completely exclude the possibility of heat loss.

Please note that such thermal insulation is the best option for decorating bath rooms.

  1. Reflective insulation Aluf Another most important advantage of this type of insulation is complete resistance to moisture. The aluminum layer will not "be afraid" of even direct ingress of water, and this will provide the material with a long service life.

  2. Due to its own technical characteristics, Alufom is able to serve also as waterproofing and sound insulation. Laying both layers will make it possible to fully solve the problem of finishing the floors.
  3. High resistance to temperatures - the operating temperature range is quite high, due to which it can be used in all regions, even in the coldest.
  4. Saving free space - the thickness of the insulation layer is not more than 0.5 cm, which will significantly reduce the cost of the required area when laying the layer of thermal insulation.

  5. Easy to install - Aluf is extremely lightweight, which makes it easy to work with. In addition, the need for the manufacture of any strength frames is eliminated - the sheets can be attached immediately to the initial surface.

Are there any tangible drawbacks to this material? The only really serious drawback of the material is the relatively high cost. It is possible to organize a high-quality insulation layer at a price almost 2 times lower. But here one should take into account the fact that the material gives moisture protection and sound protection, and therefore there will be no need to lay the corresponding layers.


Basic technical properties

The most experienced craftsmen will pay attention to the selection of insulation material first of all on technical properties, because its efficiency will depend on them. Next, we propose to consider the main indicators that affect the overall efficiency.

Several varieties of foil-clad Alufom can be distinguished, which differ in their main technical properties:

  • Aluf A - is polyethylene foam, on one side covered with aluminum sputtered foil type. Most often they are used as steam insulation, or an additional layer of insulation.

    Laying in two layers (for cool layers 3) makes it possible to create a reliable degree of protection against heat loss.

  • Aluf B - it is a polyethylene foam, which is covered on both sides with a foil made of aluminum. These are already more advanced models that have a maximum period of operation. Most often used for finishing roofs, attics, mansard rooms and others.
  • Alufom S is a particularly flexible type of polyethylene, which is coated on one side with an aluminum-type dusting, and on the other with an adhesive base.

    This will facilitate the installation process to a greater extent, because the material is self-adhesive and no additional fixing measures are required. Most often, this type is used for arranging air outlets and heating lines (when combined with kaolin).

Please note that when purchasing, you should ask the sellers for certificates of compliance.Today, quite often, under the guise of the most popular materials, they sell rather cheap, to some extent "handicraft" analogues. This is extremely important for the field of foil insulation, which the population will not have time to fully understand.

Scope of use

As mentioned earlier, Alufom has found a wide scope of use in most industries. This happened due to its high degree of efficiency, which many competitors cannot boast of. It is used for insulation:

  • Reflective insulation Aluf Attics, attics and roofs. Here high resistance to moisture will come first.
  • Baths, garages and saunas.

  • Climate systems.
  • Walls of industrial and private buildings. In this case, both external and internal insulation is allowed (in the second case, the useful effect will be much higher).
  • Water mains - in this case, material group B is used.
  • Heating boilers and underfloor heating, and this is achieved due to a wide range of operating temperatures.

    There are not so many competitors that can withstand such huge loads (the daily difference can be up to +410 degrees).

  • Transport type objects - in particular, where more often than others are used to decorate vans and containers. Its properties are ideal for such conditions.
  • Agricultural and suburban buildings.

As you can see, the material can be applied almost anywhere.


In general, Alufom insulation is an excellent material that can solve many problems. But here the high cost should be taken into account, and therefore it can be used only in cases where there is an extremely high degree of humidity (saunas, baths, baths, etc.) or when the design features do not allow the use of more massive materials.
