Light-weight roofing underlay, with self-adhesive strips

Variant without self-adhesive strips

Advantages

  • Up to 3 months of outdoor exposure
  • Well-protected building structures: highly diffusion-open and maximum protection against driving rain
  • Dry building structures: pore-free TEEE functional film actively transports moisture to the outside
  • Long-term protection thanks to the high resistance to ageing and heat of the TEEE functional film
  • Provides protection during the construction period: suitable as a temporary covering
  • Quick and reliable adhesion thanks to the integrated ‘connect’ self-adhesive strips on the long edges of the membrane

Areas of application

For use as a diffusion-open roofing underlay over roof sheathing, MDF and wood-fibre underlay panels, and over all mat or panel-shaped thermal insulation materials.
