We’re proud to confirm that Intelligent Membranes will continue our membership and support for the Passivhaus Trust — the UK’s leading independent organisation championing the Passivhaus standard.
The Passivhaus Trust is a driving force in transforming how we think about building performance. They provide:
- Education & Training — helping industry professionals understand and implement the world’s most rigorous energy efficiency standard.
- Research & Guidance — producing trusted technical resources that push the boundaries of sustainable design.
- Community & Collaboration — connecting architects, builders, engineers, and product innovators who share the same mission: delivering buildings that are comfortable, healthy, and incredibly energy-efficient.
Passivhaus-certified buildings are proven to slash energy use, enhance indoor comfort, and drastically cut carbon emissions — making them a cornerstone of the UK’s journey to Net Zero.
At Intelligent Membranes, our innovation in airtight membranes supports these goals. Our Passive Purple External remains the world’s first and only Fire Class B airtight paint certified by the Passive House Institute, enabling both airtightness and fire safety in one product.
By renewing our membership, we’re committing to keep working alongside the Passivhaus Trust and its members — sharing expertise, driving innovation, and ensuring every project meets the highest possible standards for sustainability and building performance.
Let’s keep building better, together. Contact us Now
