Description
PHS Fusion Variable Plus Window Tape is a special full adhesive for sealing window and door reveals.
PHS Fusion Variable Plus Window Tape protects against interstitial condensation by having a variable Sd membrane value. In the winter months the tape becomes more vapour closed (Sd = 20m) to prevent moisture travelling into the building fabric. Then, during the summer the tape becomes more vapour open (Sd = 0.1m) to allow any moisture that infiltrated the wall to dry out internally.
This tape is usable for internal and external sealing, offering excellent levels of vapour control either way. A full-surface High Tack adhesive, renowned for its extraordinary aggressiveness, is applied to the underside of the self-adhesive tape. This allows application even at low temperatures. The split cover foil on this self-adhesive layer allows particularly easy and time saving application. PHS Fusion Variable Plus may be also plastered and painted over and is fully concealed after installation.
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.
