VOALIT В / ВМ
APP plastomeric bitumen waterproofing membrane with glass fleece, both sides are coated on with polyethylene film (VOALIT B) or lower side is coated with polyethylene film and the upper side is coated with mineral granules (VOALIT BM). If there is a mineral granules surface it is covered with uniform layer of natural mineral slates or coloured mineral granules. There is a longitudinal strip without mineral granules on the one side for sheets overlap.
These membranes have good physical and mechanical properties and dimensional stability at wide temperature application window. They are used as bottom or finishing layer at flat roofs waterproofing of houses and administrative buildings. They can be applied for multilayer waterproofing in combination with nonwoven polyester – based materials.
