Medium-weight roof underlay, with self-adhesive zones

Variant without 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
  • 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
  • Quick and reliable adhesion thanks to the integrated ‘connect’ self-adhesive zones along the membrane strips

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.
