For the first time, you can upgrade to the performance of triple glazing without replacing your existing window frames.

Introducing our revolutionary ultra-thin triple glazing technology, designed specifically to retrofit into existing uPVC window frames. By combining advanced engineering with cutting-edge glass technology originally developed for smartphones, we’ve created a triple-glazed unit that delivers exceptional performance without the traditional weight and thickness.

At the heart of the system is ultra-thin Corning® Enlighten™ Glass, used as the centre pane within our innovative suspended monolithic glass core design. This breakthrough technology allows us to achieve the thermal benefits of conventional triple glazing in a lightweight 28mm unit.

The result? Triple-glazed performance with none of the compromises.

• Up to 50% improvement in thermal performance while keeping your existing uPVC frames
• Up to 30% lighter than conventional triple-glazed units
• Only around 5% heavier than standard double glazing
• No need to replace existing window frames
• Easier handling, installation and retrofit

Unlike traditional triple glazing, which often requires thicker, heavier units and new frames, our ultra-thin triple glazing system delivers outstanding energy efficiency while fitting seamlessly into existing window systems.

Designed for real-world performance, Corning® Enlighten™ Glass features up to three times lower thermal expansion than standard soda-lime glass. This helps reduce stress caused by temperature differences across the glass surface, minimising the risk of breakage and ensuring long-term durability, even in extreme conditions.

Triple glazing performance. Existing frames. Ground-breaking technology.
