Self-adhesive, rubberised asphalt/ polyethylene detail membrane.
For air and vapour barrier applications.
Self-adhesive, rubberised asphalt/ polyethylene detail membrane that is ideal for protecting and sealing critical areas of the building superstructure from damaging effects of the elements. By minimising air and water vapour flow through the building exterior at transition areas, the membrane seals transition and detail areas to provide a continuous air barrier and prevents premature deterioration of the building envelope. Surfaces should be primed with one coat of GCP’s solvent based primer - Bituthene Primer S2.
