Medium-weight roofing underlay

connect variant with self-adhesive zones

Advantages

  • 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

Areas of application

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