Special foam blocks are called the building blocks of white, consisting of foam and gas silicate. This material is perfect for low-rise and high-rise buildings. The structure of the raw material has a high adhesion to any decoration, but some landlords still hesitant to additional warming. The process of mounting various types of thermal insulation simple, it can be performed independently.
The urgency of the foam block insulation of houses outside
Initially penobetonovye blocks have been designed specifically for the construction of houses with single-layer walls. Thanks to the good properties of heat preservation, the building, lined with foam concrete does not require additional insulation. Due to the fact that in the vast country the winters are harsh, the builders also suggest to insulate the house with the help of various materials.
On the other hand, the concrete blocks are considered brittle raw materials, and under prolonged exposure to sub-zero temperatures may be frozen and to absorb moisture. This is done by the outside wall insulation, which provides the following benefits:
- significant savings of space, which is not true at warming the inside;
- not violated the integrity of the blocks as if the internal insulation used: an insulation layer further protects the block from freezing;
- condensate does not accumulate in, and discharged to the outside, from which is removed by the air streams.
As a finishing material on top of insulation is best to use lighter options. For example, the finishing brick is too heavy, so most builders use the paint.
types of insulation
With self-insulation of building walls of the foam blocks on the outside there is a most important question: what type of insulation to use? Professional builders offer to use mineral wool insulation foam and Penoplex. Each of these materials has certain properties, which further protects the design, allowing to keep the heat inside. Overview of the properties of raw materials, as well as the characteristics of the most popular brands and prices, will help to make a decisive choice.

The use of foam
One of the most popular types of heaters for decoration and insulation of the building facade is polystyrene or Styrofoam. Material gained success due to their properties: he did not let the moisture. The foam has a good resistance to freezing temperatures, low cost can significantly reduce the cost of insulation.

The important point is that on top of a heater of this type it is imperative to make the finishing work. The foam is not resistant to UV, so no additional finishing is needed in order to raw materials were not destroyed.
The most popular types of polystyrene foam for thermal insulation of the house of foam blocks on the outside are the brands:
- Foam Knauf Therm. It has good vapor permeability, it is available in sheets of 1x1 meter. Starting Thickness of 50 mm is used at temperatures from -140 to + 80 degrees. The cost of a single sheet starts from 150 rubles, the cost per pack of 10 pieces - 1450 rubles.
- Thermal insulation Technonikol Carbon Eco. The size of one sheet is 1180x580x30 mm, the latter figure shows the thickness of the material. Operating Temperature -70 to +75 degrees. Price per pack of 13 pieces - from 1250 rubles.
- Thermal insulation Ursa XPS. The foam is suitable for thermal insulation of facades of the foam block. The sheets are sold in size 1250h600h50 mm. 8 pieces per pack will have to pay 1100 rubles.
When insulation is necessary to pay attention to the side of the house, for example, on the south side, you can install the insulation thinner than on the north side.
Using mineral wool
The inorganic material consisting of a plurality of interwoven fibers, mineral wool has a name. This heater demand not less than the aforementioned polystyrene. The composition of the material present mountain and sedimentary rocks and metallurgical slag. The main advantages of mineral wool for insulation foam:
- high thermal insulation properties;
- heat resistance;
- high sound insulation;
- resistance to absorption of moisture;
- the operating life of 30-40 years.
The most common brand of mineral wool for insulating a company Technonikol. It offers an insulating material such as basalt TECHNOLIGHT Extra. Products supplied in a pack of plates 8 1200h600h50 mm size, while in range includes variants with increased thickness. The cost of this pack starts at 554 rubles.
Penoplex - similar foam
This material externally march to the foam, however, their production technology are different. When manufacturing Penoplex used pressure and exposure to high temperatures. The output is a very lightweight, yet durable material, which is another name for extruded polystyrene. This raw material is resistant to compression, environmental friendliness and insensitivity to moisture and mildew.
In the market of building materials for thermal insulation of facades of foam offer such options Penoplex:
- Thermal insulation Penoplex Comfort. Plates produced size 1185h585h30 mm, the thickness may vary. Material carried through 4, 7, 10 and 13 of the plates in the package. For pack of 13 plates will have to pay 1400 rubles.
- Penoplex facade. It made specially for facade insulation, available in various thicknesses from 30 to 100 mm. The cost per sheet - of $ 100 according to the thickness.
The thickness of the insulation Penoplex must comply with current regulations, it is 30 mm. Plate material is attached to the wall of the foam using an adhesive or dowels.
Features of technology of insulation various materials
When the insulating material is selected, you can proceed to the preparation. To do this, you want to make the appropriate calculations the amount of insulation, as well as pick up tools. In virtually every case it is better to perform work together with a partner, since it is more convenient to mount marker sheets together.
Of tools require special plugs with caps, when installing the foam is also necessary to mount a guide profile made of metal. You will need a drill, screwdriver, hammer. At warming "wet" method is useful specialized glue. Also need materials for sealing.
How to insulate a house of foam blocks outside of the foam?
Before you insulate the facade of foam blocks, it is recommended to make thorough preparations. Walls must be cleaned of excess sand, dirt and debris. If on the surface there are nodules mortar, they are harvested using the perforator. Foam insulation process steps is as follows:
- Priming - it will provide increased adhesion to the adhesive foam surface.
- The socket profile at the bottom of the walls - it will serve as a support for the heater.
- Preparation of adhesive - is provided with special nozzles for a drill of the type of mixer.
- Preparation of foam - the material should be roughened with a spiked roller.
- Applying adhesive to the foam using a spatula.
- Mounting foam on foam plates: made from the bottom up, on the corners and edges of the umbrella attached dowels.
When the heater assembly process is completed, it is necessary to wait some time for material shrinkage, and then proceed to finishing.
Insulation foam mineral wool: milestones
When choosing a mineral wool as insulation, certain skills are needed to work with it to perform the process according to the rules. Implement procedures better together with a partner, according to the following instructions:
- clean walls, achieving a flat surface;
- treat the area under the insulation antiseptic;
- install fasteners for crates;
- attach insulation pads;
- placed at the bottom of the guide wall socket;
- insert insulation, securing it to the anchors: they must be screwed into the wall to a depth of 40 mm;
- windproof membrane pack from above the mineral wool.
For the decoration of the facade at home, insulated with mineral wool, it is recommended to use plaster and further painting.
Winterizing using Penoplex: rules
Penoplex to use for insulation foam from the outside of the house, it is advisable to follow some rules that will help to preserve the heat inside the building without a loss. Step by step instructions is as follows:
- Alignment facade surface, sealing cracks.
- Treatment with a mixture of dirt.
- Production of adhesive.
- Gluing Penoplex plates and subsequently fixing them to the dowels.
- Installation of reinforced mesh for finishing.
In this case, the work can be done to one person, as the sheets Penoplex quickly and easily amenable to installation. The use of additional materials for the vapor barrier is not necessary, because penoplex therefore has good permeation properties of steam.
What material is most preferred: potential harm to health
If you beg the question of operational safety, then all of these materials will not bring harm to the person at the competent unit. Each of these types of materials manufactured with application antigoryuchih additives that prevent fire in case of fire and leads to self-extinguishing.
Despite the fact that in the production process of mineral wool formaldehyde binders are used, it will not release harmful substances due to the location outside the building.
Responding to a question whether the need to insulate the house, built of concrete blocks, it should be noted that the additional insulation never hurts. The use of foam, mineral wool or Penoplex only enhance the insulating properties of foam concrete and allow to preserve the heat inside the building.
