Triple28 announced as Glazing Summit Headline Sponsor

Clayton Glass’ new Triple28 triple-glazed sealed unit has been announced as the Headline Sponsor for this year’s Glazing Summit, taking place at the Coventry Building Society Arena on 8 October 2026.

With this year’s agenda reportedly firmly focused on the evolution of triple glazing, Clayton Glass said triple glazing has been talked about as the future, but are now looking forward to shaping these conversations, starting on 8 October.

Triple28 is said to have been engineered to deliver triple-glazing performance within a standard 28mm glazing profile. Designed to fit within existing double-glazing systems, Triple28 allows installers to upgrade from double to triple glazing simply by replacing the sealed unit, without needing to change window frames or glazing beads.

Traditionally, triple glazing has required deeper profiles and significantly heavier units, limiting its compatibility with many window systems. Triple28™ has been developed to overcome these challenges, enabling installers to offer the benefits of triple glazing within the standard 28mm window constructions widely used across the UK.

At the heart of the innovation is an advanced construction featuring a 100% glass monolithic core, meaning all three panes are fully recyclable while allowing Clayton Glass to achieve triple-glazing performance in a slimmer and lighter format than conventional triple-glazed units.

With a U-value of 0.8, Triple28 is designed to deliver up to 90% greater thermal efficiency compared with standard double-glazed units, helping homeowners reduce heat loss while improving comfort and energy performance.

Despite its triple-glazed construction, the unit is only marginally heavier than a standard double-glazed unit, making it practical for installation within existing frames and ideal for retrofit upgrade projects where replacing the full window would traditionally be required.

A laminated version of Triple28 is also available, offering improved acoustic performance and increased resistance to breakage for enhanced security. Triple28™ represents a significant investment by Clayton Glass in new glazing technology, designed to give installers a clear and valuable upgrade option when helping homeowners improve the energy efficiency and performance of their windows.

Ryan Green, Managing Director at Clayton Glass, said: “Triple glazing has traditionally required deeper window systems and heavier units, which has limited its adoption in many installations. Triple28 has been developed to solve that challenge by delivering triple-glazing performance within a standard 28mm sealed unit. Installers can upgrade the glass without changing the frame or profile, making it a straightforward way to deliver higher thermal performance for homeowners.

“It also gives installers a genuine additional product benefit to offer customers who want improved energy efficiency without the disruption and cost of replacing their existing windows.

“Triple28 opens up new opportunities for installers to deliver higher-performance glazing upgrades while keeping installation straightforward and cost-effective.”
