Product Information

Full details

The Intelligent Membranes Airtightness Tape is designed for professional contractors and serious DIYers involved in new construction or renovation projects who require a robust, flexible solution for sealing building junctions, windows, and doors. Its standout benefit is its moisture-dependent, four-layer technology that regulates permeability based on environmental conditions to prevent condensation. However, users should note that the tape is highly adhesive and requires careful positioning during application to ensure a clean, permanent bond.

  • Excellent adhesion to multiple substrates
  • Includes a 20mm cornering flange for precision
  • Paint and plaster compatible surface

Setup, Compatibility & Care

Ensure that all application surfaces are clean, dry, and free from dust, grease, or loose debris before installation. Apply the tape in temperatures between +5°C and +40°C for best results. When applying, press firmly across the entire surface of the tape to activate the pressure-sensitive adhesive. For corners, utilize the integrated 20mm flange to create a clean fold, ensuring there are no gaps in the seal. The tape can be stored in its original packaging in a cool, dry environment to maintain adhesive longevity.
