Roofing underlay membrane with 3D separation mesh and self-adhesive strips
Advantages
- Highest possible durability and thermostability thanks to the TEEE membrane
- Reliable drying out: highly permeable (sd value = 0.05 m ; g value = 0.25 MN·s/g ; 65 US perms)
- Protects against corrosion and ensures improved noise insulation thanks to the 3D separation mesh
- Dry building components thanks to pore-free TEEE membrane that is resistant to driving rain
- Up to 3 months of outdoor exposure
- Quick and reliable adhesion thanks to the integrated ‘connect’ self-adhesive strips on the long edges of the membrane
Areas of application
For use as a roofing underlay or facade membrane for ventilated and non-ventilated structures in combination with all roof and facade materials such as titanium zinc, aluminium, stainless steel, galvanised steel, copper etc. Fibrous membranes offer greater protection for structures and are recommended by leading providers of metal roofs for this reason. The 8 mm (5/16”) thick 3D separation mesh made of fibrous PP protects the covering against waterlogging and dampens noise caused by rain or hail.
