Balancing heritage preservation with modern thermal performance is never straightforward. That's exactly what made Trinity College, University of Oxford such a rewarding project.

Working alongside Crittall Windows, Crystal Units supplied advanced C.U.in insulated glass units within the Crittall MW40 system, achieving a centre pane U-value of just 0.6 W/m²K in a slim 32mm IGU. The result was a glazing solution that significantly improved energy performance while respecting the college's historic architecture and traditional steel window aesthetics.

Projects like this demonstrate why installers, fabricators and contractors choose Crystal Units.

Double-Glazed System.

Not all high-performance glazing technologies are new. C.U.in has been independently tested, proven in the field, and specified on projects across the UK for over a decade.

Using advanced suspended film technology, C.U.in achieves U-values as low as 0.4 W/m²K without the weight and thickness associated with conventional triple glazing. By suspending a low-emissivity film within the cavity, heat transfer is significantly reduced while maintaining a slim, lightweight insulated glass unit that can be incorporated into a wide range of glazing systems.

Unlike many of the latest thin triple-glazing solutions entering the market, C.U.in offers a proven track record. Its long-term performance has been validated through independent testing and real-world installations across residential, commercial and heritage projects, giving fabricators, installers and specifiers confidence that the product performs not only on paper, but in service.

Why choose Crystal Units?
• U-values as low as 0.4 W/m²K
• Proven suspended film technology
• Independently tested and field proven
• Successfully installed on projects across the UK
• Expert specification support from our in-house technical team
• Fast UK manufacturing with dependable lead times

At Crystal Units, we don't simply manufacture insulated glass units. We help you specify the right glazing solution from the outset, reducing risk and delivering confidence on every project.
