Components for airproofing.

Air-tightness is an increasingly important aspect in constructing and refurbishing buildings. An air-tight building shell prevents moisture from penetrating from the outside and thermal energy from dissipating from within. We have extended our range of products for the construction industry to include components for airtight buildings. We offer individual products and solutions for achieving an airtight building shell.
Our range currently comprises components for airtight connections and airtight spot penetrations. Self-adhesive windo tapes for sealing windows and complex components as well as easily-processed system components, e.g. corners and collars for wall and cable penetrations.
