SikaShield® E79 MG SA 4 mm

Self-adhesive bituminous membrane surfaced with granules and flexible at -25 °C

SikaShield® E79 MG SA 4 mm is an SBS modified bituminous roof waterproofing membrane with a thickness of 4 mm. It is reinforced with a dimensionally stable composite inlay of a fiberglass matt compressed between two layers of non-woven spunbond polyetser fabric and is flexible at -25 °C. The top surface is coated with mineral granules, which allows the permanent exposure to UV radiation. The underside of the product has a burn-off film for easy torch-application.
