Regency Glass has officially launched Regency Triple featuring Corning Incorporated, introducing a next-generation triple-glazed unit engineered to overcome the traditional limitations of triple glazing in the UK market. Developed for both replacement and new-build applications, the system delivers high thermal performance while remaining slim enough to fit within a standard 28mm cavity, a major breakthrough for retrofit compatibility.

At the core of the unit is Corning Enlighten Glass, an advanced 0.5mm boro-aluminosilicate glass used as the centre pane. Its ultra-thin profile enables Regency Triple to achieve significantly lower weight and reduced thickness compared with conventional triple-glazed systems. The unit is only around 5% heavier than standard double glazing and up to 30% lighter than traditional triple glazing, improving handling, installation efficiency, and compatibility with existing frames and hardware.

Thermal performance figures are equally notable, achieving U-values of 0.8 W/m².K in a 28mm cavity, 0.6 W/m².K in a 36mm cavity, and as low as 0.5 W/m².K in configurations above 40mm. Combined with Thermo Plastic Spacer (TPS) technology, the system also provides flexible cavity configurations while maintaining slim sightlines and consistent insulating performance.

The launch follows Regency Glass’s move into its new 420,000ft² advanced manufacturing facility at Thunderbolt Drive in Warrington. Equipped with multiple Glaston Ultra TPS lines, Hegla SortJet automation, and specialised thin-glass processing technology, the site positions the company among Europe’s most advanced IGU manufacturers and supports nationwide supply of the new Regency Triple system.
