WELDABLE MONOLITHIC BREATHABLE MEMBRANE

TRASPIR WELD EVO 360

TRASPIR WELD EVO 360 is a weldable monolithic breathable membrane for waterproofing timber roofs. It offers excellent UV stability and consists of a pair of monolithic thermoplastic polyurethane films coated on a polyester reinforcement.

TRASPIR WELD EVO 360, THE MONOLITHIC MEMBRANE THAT CAN BE HEAT OR CHEMICALLY WELDED

The monolithic structure of the TRASPIR WELD EVO 360 membrane guarantees excellent durability over time, due to the special polymers used. The double polyurethane membrane offers perfect welding on all overlapping and joints, for total waterproofing.

With the possibility of both hot and chemical welding, it makes it possible to create a single solid protective layer that is highly reliable, returning continuity to the various layers. Thanks to its mass per unit area, it can also be effectively installed on roofs with pitches greater than 5°. Also available in a 3-metre version for faster installation.

Indicazioni di posa per: PARETE

TRASPIR WELD EVO 360 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 WELD EVO 360 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.
