LITHOPLAST® PERFOR
HDPE perforated studded membrane suitable for drainage.
HDPE perforated studded membrane suitable for drainage.
The LITHOPLAST® PERFOR polyethylene studded membrane, studs are perforated at the top and thus they do not hold water. Therefore, this membrane is used as a drainage layer of open balconies and terraces, flat roofs, roof car parks, wet manufacturing areas etc.
The studded membrane creates domed cavities between the water-tight insulation and protective layers. The water that slips through the tiles and its supporting layer flows into the stud domes. These are perforated at the bottom, so that the water runs freely through the bottom insulation out of the structure or into the internal inlets. The insulation must be sloped to the properly connected drainage.
LITHOPLAST® PERFOR foils are among the proven LITHOPLAST® studded membrane series. The membranes are produced in the Czech Republic in Žďár nad Sázavou.
LITHOPLAST® PERFOR is most commonly used as a drainage layer of:
