Product description
High-class coating to be used as the only layer in the roof structure. It is a multi-layer polypropylene fabric. Highly vapor permeable pre-coverage film. This means that it is placed directly above the thermal insulation, without leaving a ventilation gap. Roofing foil regulates the processes related to condensation and accumulation of condensate, because it is so built that it is impermeable to water and perfectly permeable to water vapor.
roofing is produced by electrostatic spot lamination. Thanks to this technology, the film is flexible, strong and micro-spaces with a width of 1 ~ 2 micrometers guaranteeing high vapor permeability are evenly permeable over the entire surface of the coating, and this ensures high performance in every place.
