Heavy-weight roof underlay

connect variant with self-adhesive zones

Advantages

  • Maximal flexibility in planning construction schedules thanks to 6 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

Areas of application

For use as a permeable sarking or roof underlay on roof decking, MDF and wood fibre underlay panels, and on all thermal insulation materials.
