Overtape is a self-adhesive tape, based on a blend of butyl and other rubbers, which has excellent adhesion and will adhere to most common surfaces whilst having good movement capability. It comprises a silicone release paper, white adhesive base and an aluminium lead look top surface. Overtape is used at wall/floor, wall/wall and wall to soffit junctions, as well as for sealing around pipe penetrations, etc. It is also used with Cavity Drain R7 to seal over non-flanged laps. It is recommended that if cavity drain systems are used as a radon barrier, all lap joints in the Cavity Drain R20 and R7 must be sealed internally with Overtape.
