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.
Description
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.

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 allows the two functional TPU films to be sealed together on the outer edges, either with hot air or chemically, thus preventing humidity absorption.
Recommended use: direct UV protection is guaranteed. On roof, installation is permitted on both the internal and external sides of the building envelope; on walls, installation is permitted only on the internal side of the building envelope.
Installation: Unroll the membrane and seal using one of the two available methods: with hot air using a heat gun, or with adhesive, such as WELDING LIQUID.
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.
