MONOLITHIC AND MICROPOROUS BREATHABLE MEMBRANE
TRASPIR DOUBLE EVO 340
The monolithic and microporous breathable membrane TRASPIR DOUBLE EVO 340 guarantees excellent durability over time thanks to the double functional film . It consists of a monolithic and microporous membrane for superior mechanical resistance and water impermeability.
It is made up of a monolithic elastomer film (TPE-E), a microporous film and polypropylene protective layers, and is designed for application on the outer side of the roof .
TRASPIR DOUBLE EVO 340 , double sealing layer for double protection. Thanks to its mass per unit area, the membrane can also be effectively installed on roofs with low pitches down to 5°. The high mass per unit area and the double functional layer guarantee high abrasion resistance.
The TRASPIR DOUBLE EVO 340 membrane meets the most stringent requirements of the various national regulations, classifying it as a very high performance product.
