Driving rain proof roofing membrane for pitched roofs
Alfa Rufol UDB-A 130 is the A-classified (ZVDH), driving rain proof, high diffusion open
roofing underlay for ventilated and non-ventilated pitched roofs (also for applications above the rafters as well as on boarded roofs). It is to be applied above the thermal insulation (underneath the battens).
Suitable for the direct installation ontop of the thermal insulation. Roofing underlays for pitched roofs avoid penetration of humidity (e.g. due to driving snow) and penetration of dirt into the roof insulation.
The 3-layer structure protects the functional membrane from damages and reduces the slipping risk for the processor.
Easy handling: Auxiliary lines allow exact overlaps.
