Roger Hartshorn Recognised at GGP Installer Awards

From starting out as an apprentice toolmaker at HL Plastics to leading a management buyout, launching Eurocell and then Liniar before switching to aluminium with the launch of Garnalex and the award-winning Sheerline range - there have been many milestones along the way.

But it isn’t just within the industry that Roger’s achievements have been recognised. Garnalex received a King’s Award for Innovation 2025 for two aspects of its Sheerline system, including its patented corner construction method and Thermlock® technology.

The judges commented: “Roger is one of the most influential figures in UK fenestration. A pioneer of forward-looking product design and long-term talent development, Roger’s legacy is embedded across the industry.”

Roger said: “You won’t often see me giving speeches at conferences or events - I prefer to let our products speak for themselves, but recognition from the industry I’ve been part of for so long is hugely rewarding.

“Over the course of my career, many things have changed, but our business principles have not - our commitment to innovation, first-class service, and someone to speak to when needed. This has enabled us to become a reliable partner and created a solid foundation for the next generation of innovators and business leaders,” he added.

Alfie Hosker, Secured by Design, commented: “Secured by Design is delighted to congratulate Roger Hartshorn on this well-deserved recognition. His contribution to the fenestration industry over nearly five decades has been truly significant, with a clear commitment to innovation, quality and long-term leadership. This award is a fitting tribute to the lasting impact Roger has had across the sector, and we are pleased to see his achievements acknowledged by the industry.”
