Abstract

Thermal insulation of buildings with the use of warmth-keeping material — insulant made of mineral wool or polystyrene foam coated with thin plaster layers (ETICS) first was applied in Europe in 50 — 60s of the last century.

However the real boom in their development in Europe began after East and West Germany reunion. During 5 years only, since 1991, the use of Outside Fastened Thermo-insulation System (OFTS) has increased by three times and nowadays balances around the mark of 40 millions of square meters per year. In addition to that in Western and Central Europe it is planned to implement by 2010 the next step for reducing domestic heating costs and to fix them at the level of 1000 l of fuel equivalent per household. With that, energy losses through outside walls will amount to 10 kW•hr/sq. m.

In Russian Federation, in 1995–1998, some construction norms and regulations concerning energy saving have been also revised (for instance, Additions №3 and №4 to the Construction Norms and Regulations (CN and R) P-3-79*). New requirements to enclosing wall parts brought into force since January 1st, 2000, made the necessity to apply new energy saving materials and technologies quite evident.

So what do we get applying faсade thermo-insulation? The energy used for heating of a building makes up to 70% of total energy spent for its upkeeping. The use of thermo-insulation allows decreasing heating costs at least by 50%. Besides, the emission of contaminating substances into the atmosphere as a result of fuel burning process can be significantly reduced.
