Light-weight roof underlay

connect variant with self-adhesive zones

Advantages

  • Up to 3 months of outdoor exposure
  • Ensures reliable building components: highly diffusion-open and maximum protection against driving rain
  • 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 for temporary coverings during construction work during the construction period

Areas of Application

For use as permeable roof underlay on roof decking, MDF and wood fibre underlay panels, and on all mat or panel-shaped thermal insulation materials.
