Featured Product


KOSTER KSK SY 15 consists of a highly tear resistant, 2-layer cross-laminated, polyethylene foil with a plastic bitumen / rubber adhesive- and sealing-compound. It is cold applied and therefore no hot air or propane gas welding is required for application. Due to its high ductility, it can also be easily applied to difficult details. The membrane is highly flexible, immediately waterproof, resistant to driving rain and crack bridging. KOSTER KSK SY 15 is radon proof.
