Dörrkuplast® E-4 sk/Safeguard
Self-adhesive Elastomer bitumen sheet with combi reinforcement glass fleece/mesh lath with a safety stitch in a thickness of 4 mm.
Elastomer bitumen is highly elastic ("rubbery") and thereby remains flexible even at low temperatures.
The combi reinforcement glass fleece/mesh lath is dimensional stable, smooth in process and has excellent resistance to tearing.
The surface texture upside has a fleece and the downside is foil-laminated / silicone peel-off film.
The bonding is done by removal of the special foil. In order to ensure save adhesion of the sheet, we recommend a minimum temperature of +10°C (air and surface) during the application.
The outer half of the longitudinal seam overlap has a double-sided foil lamination. This guarantees a safe scarfing of the overlap because the inner section is already adhered by the self-adhesive bitumen mass. Therefore, a flame entry into the ground is prevented.
Dörrkuplast® E-4 sk/Safeguard is as a self-adhesive bitumen waterproofing sheet with flame protection used for flat roofs as an intermediate layer.
The fleece lamination favors a visually clean work of the waterproofing top layer.
