Discovery 135
USED AS A PRE-COVERING LAYER UNDER SLOPING ROOF COVERING FOR DIRECT PLACING ON THERMAL INSULATION OR ON THE BOARDING
Technical data
Assembly 
ParametersMaterial
Polypropylene, three-layer.Resistance
High vapour permeability and water resistance which prevent water from penetrationg into the insulating layer of the roof structure, and also protect it against moisture. This translates into reducing the energy consumption needed to heat the building.Advantages
Mechanical resistance to abrasion and tearing. Simple, safe and fast assembly. Membranes do not contain hazardous substances found in the REACH list.
