Underlay membrane with 3D release film 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 a 3D release film
  • Dry building components thanks to pore-free TEEE membrane that is resistant to driving rain
  • 3 months of outdoor exposure
  • Quick and reliable adhesion thanks to the integrated ‘connect’ self-adhesive zones along the membrane strips

Areas of Application

For use as roof lining or facade membranes 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 separating layer made of fibrous PP protects the covering against waterlogging and dampens noise caused by rain or hail.
