Thermoseal Group earns G Award Finalist Spot

Thermoseal Group has been announced as a finalist in the Component Supplier of the Year category at the 2025 G-Awards, which is said to underline its reputation as one of the UK’s most advanced insulated glass component manufacturers.

“This year’s nomination is testament to the scale of our investment in people, products and processes,” said Sales and Marketing Director Mark Hickox. “We are proud to now manufacture over three quarters of our product portfolio in-house, giving us unrivalled control over quality and performance, and enabling us to bring genuine innovation to market.”

Over the past year, Thermoseal has installed additional extrusion and lamination lines, invested in an automated packing facility, and launched a zero-waste Thermobar recycling plant – all designed to boost capacity while cutting energy use and waste.

New tooling developments have also advanced production efficiency, with 28 twin-strand tools created to support fresh Thermoflex designs and reduce material consumption.

Thermoflex, Thermoseal’s flexible spacer bar, has also been independently verified as the best performing product of its kind by both IFT Rosenheim and the BFRC.

In parallel, the company has expanded its in-house laboratory facilities, with testing equipment ensuring product compliance and performance far beyond British Standards.

Thermoseal’s acquisition by the Fenzi Group in 2024 has also reportedly created fresh opportunities across Europe and beyond, which it says positions the company at the heart of one of the most comprehensive IG component portfolios in the world.

“This shortlisting reflects not only what we’ve achieved, but also where we’re heading,” Mark added. “With the backing of Fenzi, and thanks to the commitment of our team, Thermoseal is ready to lead the way in the next generation of sustainable, high-performance glazing solutions.”

The 2025 G-Awards will take place on Friday 28 November at the London Hilton on Park Lane.
