645 Alfa FULTRA-a POWER plus (vapour permeable)
Diffusion-open window sealing tape for exterior use. The upper side of the tape has a self-adhesive strip along one side, the entire surface of the underside is coated with strong adhesive. A fibreglass mesh is attached at one side of the tape, so the tape can be fastened tightly in the plaster layer.
Vapour permeable window installation tape with mesh
Alfa FULTRA-i POWER plus with fibreglass mesh is a breathable window membrane for the fast and airtight sealing of exterior connection joints at doors and windows. The mesh guarantees a firm anchoring in the plaster layer and prevents cracks in the plaster. The tape is particularly flexible and elastic, which means it adapts to the surface perfectly and accomodates structural movement.
Thanks to the adhesive-covered underside, the application of this sealing tape is very easy and can be finished in a short time. Additional adhesive is not necessary. The self-adhesive strip on the upperside of the tape bonds to all kinds of window and door frames.
With Alfa FULTRA-a POWER plus, windows will not be soiled because no liquid adhesive is needed for the application. The combination of 644 Alfa FULTRA-i POWER plus on the inside and 645 Alfa FULTRA-a POWER plus on the outside creates a professional regulating system which prevents moisture from penetrating into the insulation.
