Polykrov – rolled material for the device of the top layer of the roofing carpet

Full description:
Polykrov is a bituminous-polymer welded roofing material based on fiberglass (glass fiber, polyester canvas) for the top layer of the roofing carpet.

The upper protective layer is a coarse-grained dressing, the lower protective layer is a film.

Polykrov contains a significant amount of bitumen-polymer binder, which makes it possible to produce roofing without the use of hot bituminous mastics.

Laying of polycrop is carried out according to the technology of mastic-free gluing – by melting the surface with the flame of a gas-air burner.
