The design of the roof on concrete base with insulation Primaplex under screed" stand the test of the group K0 and RE90. With the new construction of public and commercial buildings, as well as the renovation of old industrial buildings, which is used for roof construction with a concrete base screed over insulation, efficient use plates Primaplex. The advantages listed above make the best choice Primaplex plates in this design. In comparison with the foam that is widely used in the construction of "a screed" board Primaplex have greater strength, better moisture resistance and durability, and most importantly, a lower thermal conductivity. Application Primaplex in the classical design of the roof on concrete base, "a screed" The low thermal conductivity allows for Primaplex required value of resistance to heat transfer plates with small thickness, less than any other material. For example, for newly constructed building of the first group in the Moscow region required thickness of insulation roofing is 220 mm for the foam (PSB), 210 mm mineral wool (170 mm + 40 mm) and 140 mm for slabs Primaplex. In other words, to provide the necessary resistance to heat roofing foam construction require 60% more than Primaplex. Although the foam stamps 35 cheaper boards Primaplex-35 (approximately the same 60%), it will need more, so the amount spent on insulation foam and extruded polystyrene Primaplex, will the same. Taking into account that the plates have the additional advantage of Primaplex (minimal water absorption, higher strength, water resistance, durability), the prudent customer will opt for Primaplex. Comparison of panels with mineral wool Primaplex in the construction of "a screed" is in favor of Primaplex because the mineral wool has a large water absorption, better thermal conductivity, greater weight and less durable. Fire protection of mineral wool in this design does not play a decisive role.
