HIGHLY BREATHABLE MEMBRANE FOR WALLS
TRASPIR 95
TRASPIR 95 is the highly breathable membrane for walls with an excellent cost-performance ratio. It can be used on closed-joint façades and is designed to guarantee wind tightness, also acting as a temporary protective layer during construction work.
TRASPIR 95, the highly breathable membrane that ensures cost-effectiveness and performance.
The TRASPIR 95 highly breathable membrane consists of two layers of non-woven fabric and a middle layer of breathable polypropylene film. It is designed for application on the outer and inner side of the wall. The wind-tightness layer that it creates ensures the thermal effectiveness of the insulation, protects the envelope and improves the materials durability.
