An extremely diffusive roof underlay for installation directly on the thermal insulation or wood sheathing. The monolithic membrane guarantees higher UVResistance and far higher resistance to driving rain. Vapour diffusion through the membrane no longer occurs through membrane pores — as in non-monolithic membranes — but through vapour transmission through the monolithic membrane itself. Therefore, ensuring exceptional water-tightness against driving rain and vapour while at the same time remaining extremely breathable. Wind-Seal: Omega Quilli, Omega Nail-Seal Tape For vented & non-vented pitched roofs
UV-Stabilized for max. 4 months
Permanent protection for wood & insulation
Easy to cut , anti-glare and anti-slip
Unaffected by the influence of wood preservatives, chainsaw oil or resin.
