Prefold PHS Fusion Variable Plus is a factory folded, full adhesive tape for sealing window and door reveals. This window tape protects against interstitial condensation by controlling vapour and responding to local humidity. In the winter months the tape becomes more vapour closed to prevent moisture travelling into the building fabric; and during the summer, the tape becomes more vapour open, to allow any moisture that infiltrated the wall to dry out internally.
Prefold PHS Fusion Variable Plus is a high tack adhesive tape for internal and external use and can be applied even at low temperatures. The tape has a special structure allowing it to stretch in the transverse direction for optimal absorption of structural movement. This directional flexibility guarantees durable sealing of reveals. Prefold PHS Fusion Variable Plus can be plastered and painted over and is fully concealed after installation.
Applications:
- Window and door reveals.
- All construction types.
- Internal and external use.
