CHARACTERISTICS

Waterproofing and vapour barrier underlay composed of a polyester carrier saturated with an exclusive bituminous compound and protected by non-woven polypropylene. Characterized by excellent waterproofing properties. Stabilized against UV rays.

APPLICATIONS

Underlay for discontinuous roofing. It is recommended to use it on the second deck, more exposed to the elements and where the fixings often have larger sections, thus favoring the rapid and safe conveyance of rainwater and its rapid transfer to the eaves line. The high weight makes it an optimal product in regions characterized by a harsh climate or by high temperature ranges.
