CHARACTERISTICS

Light monobituminized underlay composed of a polyester reinforcement, with special bituminous compound and with upper external finishing in non-woven polypropylene. It guarantees perfect waterproofing. The membrane is characterized of high mechanical performances, and It is stabilized against UV rays, with anti-skid properties.

APPLICATIONS

Underlay for discontinuous roofing. It can be used under the thermal insulation as a vapour barrier and on the second wooden board, where It is more exposed to the weather agents and where the fixing systems often have larger sections; thus favoring the rapid and safe conveyance of rainwater and its rapid transfer to the eaves line.
