KÖSTER Waterproofing


KÖSTER KSK ALU 15 is cold applied and therefore no hot air or propane gas welding is required for application. Due to its high ductility it can easily be applied to difficult details. The top side of the membrane is laminated with an aluminium foil. The membrane is a vapor barrier, waterproof, weather-, and UV resistant. The self adhesive compound on the bottom side of the membrane is protected by a removable foil. It is not necessary to place a layer of gravel on top of the membrane after application. The membrane is resistant to frost and de-icing salts.
