Fixband TA ALU - for
the highest requirements
in terms of vapour tightness.

Sealing tape for the facade

Requirements are there to be fulfilled.

Even though vapour barrier sealing has long been used in façade construction on the warm side, i.e. the inside: More and more often, 100% vapour-tight solutions are required by architects and in terms of building physics. This is particularly true for connection seals in the field of air conditioning and ventilation construction, for rear-ventilated façade constructions and, above all, whenever metal meets metal. And ‘100 % vapour-tight’ is not a loose claim, but a firmly defined value that requires an sd value of over 1500 m. So it’s time to do even more justice to our own professional standards and fulfil the highest requirements for fixed sealing tapes too.

Cross-laminated, one-sided aluminium-laminated, now 100% vapour-tight fixed tape with sd value >1500 m for targeted connection sealing wherever metal meets metal.

  • For indoor and outdoor use
  • High-quality solution for demanding work in joint areas
  • 100% vapour-tight
  • Screw-through resistant
  • Fully self-adhesive over the entire surface
  • Weather-resistant and UV-stable
  • Tear and tear resistant

Always good, now even better:

The new generation of TEROSON TA ALU sealing tape.

The TA ALU Fixband from TEROSON has been something special for years because the film structure with special butyl coordination and in combination with a cross-laminated, extremely tear-resistant plastic-aluminium composite film can guarantee that it will remain tight even if it is punctured and screwed through.

In other words, it was and is the self-adhesive, high quality solution for the highest quality, watertight and screw-through-proof seals in conservatory, air conditioning and ventilation, aluminium and metal construction.

This solution is now even more watertight in the truest sense of the word – with a feature that increases the vapour tightness to over 1500 m. And thus truly fulfils the highest requirements in every respect.

The new TA ALU Fixband is screw-through-proof. This means that the vapour tightness remains intact even if the tape is drilled through.

Thanks to its cross-laminated structure with aluminium composite foil laminated on one side, the new TA ALU Fixband is highly tear and tear-resistant.
