CHARACTERISTICS

Vapour check underlay completely composed of 3 polypropylene layers welded by ultrasonic technology, which makes the material totally recyclable. It prevents infiltration of moist air, regulating the flow in the underneath roof. Stabilized against UV rays, with anti-skid properties.

APPLICATIONS

As layer of protection on the first deck under the thermal insulation, Elements suggests E-SF-140, and at the same time protects the board from mechanical stress created by the operator during the laying of the roof. On the pitched roof, the membrane offers an excellent mechanical strength performances combined with a medium average weight.
