Advantages of insulation with foam
- It is possible to carry out insulation of the walls of the house from the inside and outside. Plus, this building material is great for a roof, ceiling, floor, foundation.
- Polyfoam has high properties for heat and sound insulation, therefore the financial resources spent for heating the room are saved.
- It also has a small weight, which makes it easy to install and transport.
- It is safe and harmless to human health. During the operation of the material, no harmful substances are released( this occurs during combustion).
- Differs longevity and practicality. That's why it is convenient to use for serious buildings, designed for dozens of years.
- Many brands are practically not vapor permeable or have a minimum degree of vapor penetration( for example, PSB-S-25 brand).
- Is the most economical material. Its cost is much lower than the cost of other heaters.
It's also worth mentioning that the foam plastic is similar in structure to the shape of the balls, which are connected together. The material consists of almost 98% of the air, which explains its positive properties( hydro, heat, and sound insulation).Manufactured in Russia in accordance with GOST 15588-86.
Thermal insulation with foam, which is important to know
When insulating walls with polystyrene, it is important to take into account some of the nuances. First, the density of the material should be about 25 kg / m3 , and the thickness of the is about 50 mm .It is this thickness of foam( 50 mm) that replaces 25 centimeters of ordinary brickwork.
Secondly, the reinforced stack should have a density near 140 g / cm3 .It is made of fiberglass. Thirdly, for the installation of dowels made of plastic, not metal. Metal dowels are capable of creating "cold bridges", which are not desirable for wall insulation.
Fourthly, for the subsequent finishing only façade paint is used, which has the appropriate characteristics, that is, have high resistance to all kinds of atmospheric phenomena and ultraviolet. Its color should be the most similar to the color of the facade.
Heat insulation with foam:
technology The insulation is made from foam inside and outside the walls. But depending on the conditions in which construction work will take place, the techniques may differ slightly. If interior insulation is done, it is necessary to prepare the surface in advance. The old covering is removed, the walls are leveled and cleaned. In the end, you should get a smooth, clean and dry foundation.
Attach the heater with glue or brackets. Use a better glue mixture KREISEL.However, for a more secure fit to the wall, it is recommended to combine both methods( brackets and glue).Further on top of the heater is puttying with the help of STYROLEP glue and putty mesh, which is deeply embedded in the glue. The received base is leveled. As a result, a layer reinforced with a glass mesh is obtained. After drying, you can additionally treat the surface with a primer or paint.
Foam insulation from the outside of the is done exactly the same way, but using the insulation material PSB-C-25 .Due to the fact that it has high resistance to temperature changes and physical shocks( which is important when decorating facades).Plus, it is recommended to cover this material with a "coat"( special technology of plaster walls).This will relieve the outer coating from all sorts of scratches and other minor defects. In the rest, the work is no different.
Important note! Detailed technique and mandatory standards that must be observed when wall insulation are prescribed in SNiP 11-3-79.Before starting any work, it is important to read these rules.
