Vapour open (vapour permeable), weldable roof underlay for very flat under-roofs. Use for roof pitches starting from 1.5°. UV stability: 5 months Prefabricated customisation possible

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 integrated adhesive strips. Use for roof pitches starting from 5°. UV stability: 6 months

is a non-vapour retardant roof underlay with two two-way acrylate adhesive strips for installation directly on the thermal insulation or the wood sheathing. In accordance with ÖNORM B 4119, the roof underlay is suitable for rainproof under-roofs as well as for under-roofs with increased rainproof properties with a roof pitch of > 15° and a snow load sk of up to 4.0 kN/m² and complies with the classification UDB-A and USB-A in accordance with the ZVDH Directive (ZVDH = German Central Association of the Roofing Trade).

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

Omega 180 Underlay is an extremely diffusive roof underlay for installation directly onto the thermal insulation or wood sheathing. The standards according to ZVDH must be observed. Wind-Seal: Omega Quilli, Omega Nail-Seal Tape.

Omega Light Roof Underlay is an extremely diffusive roof underlay for installation directly onto the thermal insulation or wood sheathing. With integrated adhesives. The standards according to ZVDH must be observed. Wind-Seal: Omega Quilli, Omega Nail-Seal Tape

An extremely diffusive underlay for installation directly on the thermal insulation or wood sheathing.

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. Wind-Seal: Omega Quilli

Weather-resistant 3-layer roof sheeting with vapour delaying effect for all insulation on battens.

A highly vapour-permeable, 3-layer wind-tight membrane, made from textured polypropylene for installation directly on to external wood sheathing, such as OSB, panel vent or wood fibre board and thermal insulation. Omega Wind Seal protects the structure and the thermal insulation against the effects of wind and moisture while allowing the wall make-up to breathe and dry out towards the outside.
