Protegga is a multi functional polypropylene membrane developed as an underlay for ceramic tiles and natural stone. It acts as an “uncoupling” membrane on all suitable substrates and as a water vapour pressure equalization membrane against dampness in the substrate.


Protegga is a polypropylene membrane with a specially designed structure of square studs, each cut back in a dovetail configuration or undercut, with an anchoring fibre fabric laminated to its underside. Protegga is approximately 3 mm high. Protegga’s distinctive red colour creates a useful contrasting background for installers to ensure full adhesive coverage.
