Izokrov – rolled material for the device of the lower layer of the roofing carpet
Izokrov is a bitumen-polymer welded roofing material based on fiberglass (fiberglass, polyester canvas) for the installation of the lower layer of the roofing carpet. The upper and lower protective layer is a film.
Izokrov contains a significant amount of bitumen-polymer binder, which makes it possible to produce roofing without the use of hot bituminous mastics.
Isokrov is laid using the technology of mastic-free gluing – by melting the surface with the flame of a gas-air burner.
Is issued in rolls.
Roll width – 1±0.01 m.
Roll length 10 m.
Roll area 10±0.5 m2.
