TECNOAIR is a triple layer thermo sealed membrane, consisting of two nonwoven polypropylene spunbonded felts, with a micro porous breathable and waterproofing layer
The house and the roof in particular, need to breathe to allow a healthy living environment, free from mold and aerobic mildew and keep the insulation thermal value
  • Protects your roof from rainwater infiltration, snow, wind and dust.
  • Allow the roof breathing, promoting the steam discharge and avoiding the condensation problems
  • It keeps unchanged the thermal insulation values
  • Easy and light to install
  • No maintenance required
  • Fully recyclable
Apply the TECNOAIR rolls at the wooden support extrados, transversally to the ground slope, starting the installation from the eaves line, providing 20cm overlaps. The mechanical fixing can be effected by the use of large-headed nails or metal staples. On the top of the sheets must overhang on the opposite pitch to allow the overlaps. Even if TECNOAIR is waterproofing, it’s recommended  its protection with an upper waterproofing layer.

TECNOAIR should be stocked horizontal, on a clean and flat surface away from direct sunlight.
