Light, full-surface adhesive, permeable airtightness and weathering-protection membrane

Advantages

  • Protects the structure: Diffusion-permeable and maximum protection against driving rain
  • 4 weeks of outdoor exposure to protect floors during construction
  • Keeps building components dry by means of a pore-free moisture-active functional membrane
  • Easy and reliable installation thanks to its split release film - sticks immediately to subsurfaces with sufficient load-bearing capacity
  • Permanent protection thanks to the high resistance to ageing and heat of the TEEE membrane
  • 3 months of outdoor exposure for inclined roofs and walls

Areas of application

Steep roofs and walls

Allows airtightness to be achieved on wood-based products and mineral subsurfaces – e.g. on the exterior side of unplastered (fair-faced) masonry or concrete components with joints. For roofs, it also fulfils the requirements of the Central Association of the German Roofing Trade (ZVDH) for an underlay and for temporary coverings for the specified time period.

Temporary protection for ceilings/floors during construction

Thanks to its full-surface adhesion, this product provides temporary protection for intermediate ceilings and floors on multi-storey CLT (cross-laminated timber) or wooden-frame buildings during the construction period.
