Subroofing film of Elkatek Standart - the transparent reinforced waterproofing or paroizolyatsionny film. It is applied to a waterproofing and a paroizlyation of steep roofs (protection against wind and water) if keeps within over the warming material, it is necessary to leave 50 mm an air interval for ventilation. For a waterproofing this film with microperforation, for vapor barrier – without mikroperforation.
Density of a film is 70-100 g/sq.m.
