Glazing That Meets the Highest Energy Standards
Passivhaus is widely recognised as the most rigorous energy performance standard in construction. Our glazing systems are engineered specifically to meet its demanding thermal requirements – delivering exceptional comfort, reduced energy demand, and lasting performance in even the most ambitious low-energy builds.
What Is Passivhaus and Why Does It Matter?
Passivhaus is a tried and tested building performance standard, not a brand – applicable to any building type, anywhere. Achieving Passivhaus certification means the building has been designed and built to deliver space heating and cooling energy savings of up to 90% compared to conventional building stock.
The standard prioritises airtightness, insulation, and the careful management of heat gains and losses. Windows and doors are critical to achieving this, which is why the choice of glazing system – its U-values, frame performance, and installation detailing – has a direct impact on whether a building reaches certification.
Thermal Comfort Throughout the Year
In a Passivhaus-certified building, internal surface temperatures remain consistently close to the ambient indoor air temperature – even during extreme outdoor conditions. This is achieved through a combination of highly insulated building fabric and high-performance glazing that minimises heat loss in winter and unwanted solar gain in summer.
Our triple-glazed Aluclad systems are designed to contribute directly to this performance. With whole-window U-values meeting Passivhaus thresholds, they help maintain the stable internal environment that defines the Passivhaus standard.
Specification Support for Low-Energy Projects
We work alongside architects, Passivhaus consultants, and self-build clients to identify the most appropriate glazing system for each project’s energy strategy. Our technical team can provide U-value data, frame performance figures, and installation detailing guidance to support your specification from the outset.
Early engagement is strongly recommended for Passivhaus and low-energy projects. The glazing specification needs to be integrated with the wider building fabric design, and our team can advise on product selection, sizing constraints, and installation methodology before design is finalised.
A Sustainable Approach to Glazing
Environmental responsibility is central to how we design and manufacture our products. Our timber is FSC-certified, and our manufacturing processes are aligned with modern sustainability standards. We hold Blue Sky Certification as further evidence of our commitment to responsible sourcing and environmental performance.
Passivhaus glazing is, by its nature, a long-term investment in the environmental performance of a building. Our products are designed with a 60-year service life in mind – reducing the embodied carbon impact of replacement and the long-term running costs of the buildings they serve.
