CHARACTERISTICS

Highly breathable underlay composed by 3 layers in polypropylene welded with ultrasonic technology. The absence of glues and harmful substances makes the product totally recyclable with high breathable properties. Stabilized against UV rays. It has anti-skid properties.

APPLICATIONS

Placed in direct contact with the thermal insulation on the cold side of the structure, it allows a rapid evacuation of excess water vapour through the under-tile ventilation, helping to improve the thermal properties of the insulating material.
On the pitched roof, the membrane offers an excellent mechanical strength performances.
