Omega Mono - Model 200 Undelay -Roofing Membranes

An extremely diffusive roof underlay for installation directly on the thermal insulation or wood sheathing. The monolithic membrane guarantees higher UV resistance and far higher resistance to driving rain. Vapour transmission through the functional film is no longer a result of capillary conduction but transport is active from the interior to the exterior through the non-porous membrane. Water-tightness and UV-resistance are therefore retained even under the influence of wood preservative, chain saw oil or resin.
