Garnalex has officially announced it has received a coveted King’s Award for Innovation 2025 for its Sheerline aluminium windows and door range. With only 46 businesses being recognised in the innovation category this year it is testament to how game changing the Sheerline system has been.

Two innovative aspects in particular were highlighted by the awards process. Firstly, Sheerline’s patented construction method, which not only reduces waste and locks in quality, but also results in better looking windows with less misalignment in frames for improved aesthetic appeal. 

In addition, Thermlock®, Sheerline’s proven proprietary thermal technology was highlighted. Aside from offering greater thermal efficiency than legacy polyamide systems, easily achieving Part L compliance with competitive U-values, it also allows installers to fix through the optimum area profiles as it’s less brittle than polyamide. 

Thermlock® is also a key ingredient in Garnalex’s market leading agility and ability to deliver consistently on its 5-day lead-time promise, as it allows finished profiles to be assembled close to dispatch.

It has differentiated itself in a competitive industry by focusing on product innovation, its customers and first-class service, and delivering on its promises. This approach has enabled it to blaze a trail where others have lost momentum.

Roger Hartshorn, Garnalex’s CEO, said: “It is a privilege and an honour to be able to share the news that Garnalex has won the prestigious King’s Award for Innovation. The fenestration industry has always been a competitive industry, where accolades such as this make a real difference.”

“Not only will it enable us to continue to stand out in an increasingly crowded space, but it highlights the far-reaching impact we’re having as a company. We look forward to celebrating and bringing even more industry-changing innovations to market,” he added.

The Award programme, now in its 59th year, is the most prestigious business award in the country, with successful businesses able to use the esteemed King’s Awards Emblem for the next five years.
