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 three versions:
ASPIRA Std
- Pre-covering membrane
- An economical solution for any type of roof
ASPIRA Plus
- Excellent vapour permeability
- High strength
ASPIRA Max
- Roofing screen class
- High performance under extreme conditions
All membranes of the Aspira series meet the pro-ecological requirements of modern buildings. In each version and type, they are 100% recyclable, suitable for reprocessing, and in the production cycle they do not generate landfill waste.
