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 .
Description
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.

Description
The application surface must be dry, free of dust and grease. Surface elements must be removed so that the membrane is not damaged during application.
The membrane is made of double functional membrane for double watertightness and weather protection.
Recommended use: direct UV protection is guaranteed. Installation is therefore permitted on both the internal and external sides of the building envelope.
Installation: Unroll the membrane. If the version without double-sided adhesive strips is used, sealing must be carried out using tape such as: FLEXY BAND, FLEXY BAND UV, SPEEDY BAND, or EASY BAND.
Ensure that the overlap between the membranes is at least 15 cm to achieve an optimal seal.
To ensure correct and professional installation, the use of a nail sealing point is required.
Further details regarding installation can be found in the specific instructions provided by the supplier.
