Reinforced roofing underlay, with self-adhesive strips

Variant without self-adhesive zones

Advantages

  • Extremely robust thanks to reinforcement: suitable for blown-in insulation materials
  • Flexible planning of construction schedules thanks to 4 months of outdoor exposure
  • Ensures reliable building components: highly diffusion-open and maximum protection against driving rain and hail
  • Dry building components: pore-free TEEE functional membrane actively transports moisture to the outside
  • Permanent protection thanks to the high resistance to ageing and heat of the TEEE membrane
  • Reliable during the construction phase: suitable as a temporary covering during the construction period
  • 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 on roof sheathing, MDF and wood-fibre underlay panels, and over all thermal insulation materials, including blown-in insulation materials.
