Membrane Tapes

- to seal the membranes
Construction membranes should be carefully sealed to maximise their effectiveness. Walki wishes to reduce the risk of condensation if overlapping joints are not properly sealed or too weak. Sealing tapes have been developed based on Walki membranes to ensure perfect compatibility between Walki membranes and Walki tapes. Walki®FR Tape Walki has developed a specific tape to be used with Walki® Wall Tight FR G A2 165 membrane so the full system tape membrane could be certified with a reaction to fire A2-s1, d0. The Walki® Wall FR G A2 215 tape itself has a reaction to fire Euroclass B - s2, d0.
