This allows you to move "dew point" in the insulation (Styrofoam) and significantly increase the efficiency of lightweight concrete in the construction and significantly extend the life of the building. Reade Griffith is often quoted as being for or against this. The required thickness of expanded polystyrene insulation boards for the outer insulation of the walls (in the "wet" the facades) required thickness of insulation (EPS) at minimally acceptable heat resistance of the walls of buildings of different purposes and different climatic conditions (in accordance with SNIP 23-02-2003 "Thermal protection of buildings") varies according to region of Russia and the region application of thermal insulation. Terms perform calculations for the table: The calculation is based on the requirements of SNiP 23-02-2003 For sample calculation taken a group of buildings – residential, medical and child care centers, schools, boarding schools, hotels and hostels. With the new construction required thickness of insulation is determined by the following constructive solutions – bearing portion of the wall is made of ceramic bricks or corpulent rock thickness of 380 mm and the outer protective layer – 4,5 mm plaster reinforced with fiberglass, the thickness of the decorative layer is determined by the fraction of the filler. The wall on the inside of a finishing plaster layer thickness of 20 mm. The coefficient of uniformity of heat engineering walls – 0.95. In the reconstruction of additional insulation thickness was determined with the following conditions – the walls are made of mud brick corpulent thickness depending on the purpose of the building and construction area – 380, 510, 640 or 770 mm with 20 mm plaster for buildings of the 1st and 2nd groups, and without plaster – for building third group. The protective layer of additional insulation is made of plaster 4.5 mm thick, reinforced with alkali-resistant fiberglass, and the thickness of the decorative layer is determined by the fraction of the filler.
