642 Alfa FULTRA-a POWER (vapour permeable)
Diffusion-open window sealing tape for exterior use. While 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 for an easy and reliable application.
Vapour permeable connection joints for doors and windows
Alfa FULTRA-a POWER is a breathable window membrane for the fast and airtight sealing of exterior connection joints at doors and windows. Thanks to the adhesive-covered underside and the silicone paper which is parted in the middle, 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. The tape is particularly elastic, which means it can accomodate structural movement without any difficulties.
With Alfa FULTRA-a POWER, windows will not be soiled because no liquid adhesive is needed for the application. The combination of 641 Alfa FULTRA-i POWER on the inside and 642 Alfa FULTRA-a POWER on the outside creates a professional regulating system which prevents moisture from penetrating into the insulation.
