STOPGAP ISOLATOR MEMBRANE is an impervious loose lay sheet designed to be laid over damp or contaminated subfloors prior to the installation of a wide range of sheet vinyl, linoleum, rubber floorcoverings and bitumen backed carpet tiles. The membrane has nodules on the underside to create an airspace allowing ventilation of water vapour from a damp subfloor into a dry wall, thereby allowing impervious floorcoverings to be bonded quickly and easily.

STOPGAP ISOLATOR MEMBRANE is ideally suited for fast-track projects where time required for traditional subfloor preparation is not available, for heritage projects where removal of the existing floor is not possible and for temporary coverings where floors need to be returned to their original state. It is not suitable for use in biologically sensitive areas such as hospital wards, operating theatres or in secure areas such as prisons or psychiatric units. Being a loose lay system, STOPGAP ISOLATORMEMBRANE does not have the sound attributes of a fully bonded system and as such, a slight increase in noise levels may be experienced when trafficking.
