Reinforced roofing underlay, with 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 roofing underlay on roof decking, MDF and wood-fibre underlay panels, and over all thermal insulation materials, including blown-in insulation materials.
