Self-Adhesive Window Tape "Multi Power", 70mm x 25m


The Multi Power Window Tape is a self-adhesive window tape, which can be used for the internal and external sealing of window joints.

The tape is completely air tight and creates a vapour inhibiting barrier.

We supply the tape only in 70mm width for timber frame structures.

Because of the roughness of the concrete blocks, we do not recommend the use of self-adhesive tapes for standard masonry.

The tape is UV resistant for up to 12 months and can be painted or plastered afterwards.

The Multi Power Window Tape meets the stringent criterias for window sealing according to EnEV and RAL.
