Aspira Vapour breathing membrane

The latest ASPIRA 3-ply vapour breathing membranes provide breathability for the roof slope, a condition crucial for the health of the entire building.

The vapour membrane lets the structure “breathe out” the moisture accumulated within the thermal insulation system, while preventing the ingress of water from the outside. The ASPIRA vapour breathing membranes are waterproof and highly permeable to water vapour. The three plies of polypropylene also ensure high tensile and yield strength.

The membranes are available in two versions:

ASPIRA Plus

  • Excellent vapour permeability 
  • High strength

ASPIRA Max

  • Roofing screen class
  • High performance under extreme conditions
