Ensuring the Durability of Buildings through the Use of Insulation Systems Based on Polyethylene Foam

In modern polymer composite technology, the use of waste products from other industries or processed is reasonable, but this requires more research. The purpose research presented in article was to develop a methodology for selecting composition modified polyethylene foam and assess flammability materials obtained. these studies, content recycled polyethylene, as result solving optimization problems, taken be equal 23% mass polymer. CO2 used foaming gas. structure with flame retardant. This made it possible obtain belonging group flammable, self-extinguishing materials, which significantly expanded field application based on foam. Taking into account possibilities seamless insulation casings, following systems are considered: floors under mechanical load ground; permafrost soil insulation; external building elements harsh climatic conditions; floating floors.
