Thin Triples

Weight-Saving Design, Without Compromise

At just 21 kg/m², Regency Triple® is roughly 30% lighter than a standard triple-glazed unit (30 kg/m²) and only 5% heavier than a standard double-glazed unit (20 kg/m²). This gives installers and manufacturers the thermal performance of triple glazing without the weight penalty, making handling, fitting, and operation dramatically easier. It also removes the need for the heavy-duty hardware typically required for standard TGUs, streamlining both new-build and renovation projects.

Advanced Glass Technology

At the heart of Regency Triple® is Corning® Enlighten™ Glass, which delivers high thermal durability and helps protect against field thermal breakage without the need for tempering or toughening. This ensures long-term reliability while simplifying manufacturing requirements.

Slim Cavity, Full Triple-Glazing Benefits

Thanks to the use of a Thermo Plastic Spacer Bar (TPS®)*, Regency Triple® supports bespoke cavity widths, allowing the full benefits of triple glazing to be achieved within a compact 28mm cavity. This makes it ideal for the replacement window market, where space and frame compatibility are critical.

Thermal Performance and Efficiency

Regency Triple® delivers strong thermal insulation and improved energy efficiency, without the need for bulky frame modifications — helping to future-proof installations while keeping design simple.

Sustainability and Compatibility

Beyond performance, Regency Triple® offers a genuinely sustainable choice, with a lower carbon footprint than traditional soda-lime glass thanks to its lightweight construction. It’s fully compatible with standard window and door installation practices, making it a straightforward drop-in upgrade for both new builds and renovations.
