Foamed plastic in system of operated roofs

The paper discusses the foamed plastics which have a low density and thermal conductivity, satisfactory resistance to sol-frames weak acids and bases. It is noted that a common drawback is their flammability. Basic research methods are based on regulatory requirements and test methods recommended for foamed plastics. In the process, results were obtained on the properties of foam isocyanates and studied their performance on compliance with the requirements for roof insulation. The prospects of the use of these materials as insulation in systems operated roof.
