ISOCELL OMEGA G20 facade membrane 185 g/m²

ISOCELL OMEGA G20 – a solid base for a durable facade
ISOCELL OMEGA G20 is a high-quality and durable diffusion facade membrane designed for use in ventilated timber facades. The membrane effectively protects building structures from wind and rain while allowing moisture to safely escape from the construction.

Thanks to the UV-stabilised surface, OMEGA G20 SK DUO can remain exposed for a longer period during construction while maintaining its technical properties and functionality. This makes the product a reliable solution for both new construction and renovation projects.

The strong yet flexible material is easy to handle and suitable for use behind open-joint facade cladding systems.

OMEGA G20 is a practical choice for builders and designers who value structural durability, reliability and a high-quality final result.

Best features
• Effective wind and rain protection
Protects facade structures from external influences and helps maintain thermal performance and energy efficiency.

• Very good vapour permeability (diffusion membrane)
Allows moisture to escape from the structure, reducing the risk of condensation and moisture damage.

• UV-stabilised surface
Suitable for applications where the membrane remains exposed for longer periods during construction.

• Strong and durable material
Good tear resistance and mechanical strength even in demanding installation conditions.

• Non-reflective black surface
Visually suitable behind open-joint cladding and does not show through finishing materials.

Where to use

• Ventilated timber facades
Ideal solution behind timber cladding and other ventilated facade finishes.

• Open-joint facades
Suitable for facades where visible gaps are left between finishing elements.

• New construction and renovation
Applicable for both new buildings and facade refurbishment projects.

• Private houses and low-rise residential buildings
Well suited for timber frame buildings and smaller housing projects.

• Utility buildings and technical structures
Also suitable for garages, sheds and other timber-structure buildings.
