Thermal insulation of a frame house. Evaporation materials.

Spray insulation materials manufactured using special equipment.

sprayed ecowool

Ecowool can be used as the particulate material, but can be used as napylitelya. As part of this material is present lignin - the substance, which acquires adhesive properties when wet. Ecowool sprayed in several ways:

- Ecowool can be sprayed after sewn up one of the sides of the wall. Material is sprayed over the entire surface and then leveled using a roll of carcass racks level.
- The frame is closed on two sides obshivnym pictures, then there are drilled 55-60 mm holes into which the heater is supplied under pressure.

Cellulose Fiber spraying is performed using special equipment. It ecowool fluff mechanically, then it is shaken up and moistened. Further pressure is applied to the finished corrugated insulation sleeve from which is applied to the prepared surface. simpler equipment can be used if you wish to ecowool spraying, but then have to manually ecowool fluffs.

Polyurethane foam

This insulation 90% filled with inert gas, this explains the high insulating properties of the material. The material is well adhered to any surface. After applying it begins to solidify, thus expanding and filling all voids. It obtained a homogeneous mass, without joints and other areas that contribute to heat loss.

Polyurethane foam is made from petroleum or from vegetable components. Depending on the production technology can change the density of insulation from very soft to hard. To apply the insulation frame construction with a hardness of about 40 kg per square meter. However, if you want to do without waterproofing coatings, insulation can be applied with greater rigidity.

The main advantages of polyurethane foam:

- high ability to adhere to different free of dirt and dust surface.
- The ability to expand, which eliminates unnecessary heat loss.
- Excellent sound insulation properties.
- Polyurethane foam is not exposed to the negative impacts of biological: rot, mold and so on. It does not infest the mouse and rat.
- Speed ​​of installation. An experienced team will make spraying in the house one day. Hardening process takes only one day, then it is possible to continue construction work.

Disadvantages of polyurethane foam:

- The main drawback of the material - flammability. According to GOST material is readily flammable and self-extinguishing materials.
- Material does not like sunlight, so it should be shut down immediately after application.
- The high cost of the material and work on its application. However, the cost is more than compensated high insulation properties of this technology.

insulation manufacturers offer single-use devices for applying foam. Therefore, every handyman can independently without special equipment applied sprayed insulation.

In the next article we will talk about the warming of the frame house with the help of insulation in the form of panels or mats.
