TRASPIR WELD EVO 360
WELDABLE MONOLITHIC BREATHABLE MEMBRANE
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.
