Medium-weight roofing underlay

connect variant with self-adhesive strips

Advantages

  • Flexible planning of construction schedules thanks to 4 months of outdoor exposure
  • Well-protected building components: highly diffusion-open and maximum protection against driving rain and hail
  • Dry building components: pore-free TEEE functional film actively transports moisture to the outside
  • Permanent 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

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.
