VAPOUR PERMEABLE MEMBRANE
UNILIT MEMBRANE is a breathable layer especially designed for pitched roofs. It can also be applied as a protection against rain behind claddings, or behind a plaster system reinforced by a stainless steel brickmesh.
UNILIT MEMBRANE is composed of four very strong layers which are rain tight and still breathable. It consists of two polypropylene meshes on the external side, a microporous film and a polypropylene reinforcement.
UNILIT MEMBRANE can be applied straight on the underlaying substrate (insulation or solid board) or the frame.
The membranes are placed overlapping over each other (5-10 cm), and are sealed with an airtight adhesive tape, e.g. waterproof solid glue.
