Roof waterproofing membrane TGF 20

drainagefor walkwaysnon-slip

Separation and slip sheets, as loosely laid tarps or sheets, protect the waterproofing from tensile and shear forces. In the case of chemically incompatible materials (e.g. single soft PVC sheets on bitumen), a neutral separation layer has to be installed. Only vapour permeable membranes (e.g. TGV 21), and no vapour barriers, should be used over an XPS insulation in inverted roof constructions, in order to avoid condensation within the insulation. Chemically neutral high-pressure-polyethylene sheet for application as separation and slip sheet on green roofs, for walkways and driveways; compatible with bitumen and polystyrene; resistant to most chemicals; UV-stabilized; smooth surface; vapour barrier (Sd ≥ 100 m); colour: black; thickness: ca. 0.20 mm; weight: ca. 190 g/m2.
