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.
An extremely diffusive roof underlay designed for use under metal covering. It is equipped with 3-dimensional polypropylene mesh fabric and is laid directly on the wood sheathing. The mesh fabric protects the sheeting from heat and damage from the metal and guarantees that the underlay is ventilated from above.
Vapour permeable roof underlay for roofs where there is an increased need for raintightness
in accordance with ÖNoRM B 4119.
Anti-slip and stable. With two intergated adhesive strips. Use for roof pitches starting from 5°.

is a moisture-variable vapour barrier for use in the air-tight layer. The functional membrane changes its diffusion resistance depending on the current humidity. During the winter months room atmosphere is generally dryer. The sd-value of the vapour barrier increases. This process results in the penetration of only a little water vapour into the construction and/or into the insulation. In summer, when there is sufficient solar insolation, the relative humidity behind the membrane is higher as a result of reverse diffusion. The water molecules are stored in the membrane. The sd-value sinks, causing more water vapour to escape from the construction and into the rooms and the building element becomes dryer.
