Roofing pie

Abstract

This utility model relates to construction and is intended for the use of fiber cement boards in roofing systems as a rigid sheet base beneath a waterproofing layer. The roofing structure utilizes autoclave-dried fiber cement board, which provides increased moisture resistance, strength, and fire safety for the roofing system compared to cement-bonded particle boards. The roofing structure comprises a roof base, a thermal insulation layer, and a waterproofing layer, additionally containing a vapor barrier located between the base and the thermal insulation layer. It also further comprises a rigid autoclave-dried fiber cement board approximately 10 mm thick, with a surface treated with a bitumen primer, positioned between the thermal insulation and waterproofing layers.
