Effective Floors and Roofs Using Polyethylene Foam

Insulation systems using polyethylene foam with a seamless connection have proven themselves in the insulation of hangars, warehouses of agricultural products, livestock facilities, production facilities, garages. An independent area of their application can be insulating layers in flat roofs, including those roofs in operation, or in floating floor systems. The top layer of the structure can be made using reinforced concrete screed as well as fiber-cement or chrysotile cement sheets, and in this case there is a floor of dry assembly. The purpose of the research described in the article was to study the properties of foamed polyethylene and verify the results obtained during the reconstruction of an industrial building, as well as confirming the possibility of a seamless insulation shell obtaining in during installation of industrial floating floors using patented technology TEPOFOL (Patent No. 2645190). Results of the studies show that the compressive strength at 10% deformation depends on the thickness of the insulating layer and the area of application of the load, which is explained by the structural features of foamed polyethylene. With large areas of insulation, the insulation layer of foamed polyethylene withstands the loads typical of both «floating» industrial floors and flat exploited roofs with reinforced concrete screed over the insulating layer.
