Uses of Radbar Double-Sided Tape

Radbar double-sided tape is compatible with damp proof membranes, radon membranes and gas barrier membranes.

Using Radbar Double-Sided Membrane Tape

The DPM double-sided tape is applied to the existing laid out DPM sheet. Where the subsequent sheet overlaps it, apply pressure to create the taped seal.
