Traspir Evo 90

Monolithic Watertight-Airtight and highly vapour permeable membrane.

Monolithic elastomer (PE) film, extruded between two polypropylene (PP) protective layers.


High water-tightness and excellent weather resistance thanks to the special extruded mix.

B-s1, d0

Flame retardant certification, Euroclass R reaction to fire B-s1, d0 based on EN 13501-1. FI ≤ 5 to AS1530.2

Thermal Stability

The combination between polyester and the special membrane provide high thermal stability, up +100˚C.

Example of membrane use in one type of detail.

Membrane can be used in numerous different typologies.

Thanks to the special chemical composition that is flame retardant. It is suitable for use in applications on facades in direct contact with the ventilation chamber, or in cases in which the product is visible in internal environments.
