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.

Indicazioni di posa per: PARETE

TRASPIR DOUBLE EVO 340 is laid parallel to the dock beam or the floor if laid on a wall. The second layer must be overlapped by at least 15 centimetres. Each layer must be fixed to the substrate with a mechanical fastener. (ex: HAMMER STAPLER, HAND STAPLER o PNEU STAPLER). It is also advisable to overlap the sheets by at least 30 centimetres at the butt joints. In order to achieve correct air and water sealing, we recommend the use of EASY BAND, SPEEDY BAND, FLEXI BAND, FLEXI BAND UV, SOLID BAND, PLASTER BAND, SMART BAND, FACADE BAND UV, FRONT BAND UV, FRONT BAND UV 210, DOUBLE BAND, SUPRA BAND, BUTYL BAND, OUTSIDE GLUE, FIRE SEALING, FIRE STRIPE or in the case of rough surfaces (such as rough OSB) FLEXI BAND, PRIMER SPAY, PRIMER .

Indicazioni di posa per: TETTO

TRASPIR DOUBLE EVO 340 is placed parallel to the eaves line, starting from the lower edge of the roof. The second layer must be overlapped by at least 10-20 centimetres to the previous one (depending on the slope of the roof), as indicated on the layout according to UNI 11470:2013. The sheet must be applied on a continuous support with a mechanical fastening device. (ex: HAMMER STAPLER, HAND STAPLER o PNEU STAPLER). Once at the top of the roof, it is advisable for the membrane to protrude beyond the ridge line by at least 30 centimetres to ensure a perfect overlap with the strips of sheet that will overlap on the other side of the roof. It is also recommended that the sheets overlap by at least 30 cm even at the end joints. To achieve correct air and water sealing, we recommend the use of EASY BAND, SPEEDY BAND, FLEXI BAND, FLEXI BAND UV, SOLID BAND, PLASTER BAND, SMART BAND, FACADE BAND UV, FRONT BAND UV, FRONT BAND UV 210, DOUBLE BAND, SUPRA BAND, BUTYL BAND, OUTSIDE GLUE, FIRE SEALING, FIRE STRIPE. If there is an integrated double adhesive strip, it can replace the correct air and water sealing.
