Reinforced roof underlay, with self-adhesive zones

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 zones on the long edges of the membrane

Areas of application

For use as permeable roof underlay on roof decking, MDF and wood fibre underlay panels, and on all thermal insulation materials, including blown-in insulation materials.
