Senior’s PURe aluminium window system wins King’s Award for Enterprise

  • 7 Jul 2023

After becoming one of the first ever winners of a King’s Award for Enterprise, Senior Architectural Systems has attended an official presentation ceremony at Buckingham Palace.

The UK’s largest privately owned aluminium fenestration systems manufacturer was presented with a prestigious award for innovation in recognition of its patented PURe aluminium window system which can achieve exceptional thermal performance and energy efficiency.

Lennart Jonsson, Senior’s founder and inventor of the PURe system, represented the company at the exclusive event, alongside the other winners of the 2023 King’s Award for Enterprise and King Charles III himself.

The Duke and Duchess of Edinburgh, the Duke and Duchess of Gloucester, Environment Secretary Therese Coffrey, and Business and Trade Secretary Kemi Badenoch were also in attendance at the reception dinner, which was held on 27 June at Buckingham Palace.

‘A real honour’

Lennart Jonsson comments: “It was a real honour to visit the palace and meet our fellow award winners as we came together to celebrate the success of different businesses from across the country.

“Senior has been at the forefront of the UK aluminium fenestration industry for over 30 years and this was definitely one of the biggest highlights of our journey so far. We are incredibly proud of our unique PURe® aluminium system and it’s wonderful to see the range, and the talents of all of the people here at Senior that have helped to create it, recognised with such a prestigious award.”

Senior is one of just 148 organisations nationwide to have received a prestigious King’s Award for Enterprise.

The King’s Award for Enterprise recognises and celebrates business excellence across the UK, focusing on the four categories of innovation, sustainable development, international trade, and the promotion of opportunity through social mobility.

Senior’s innovation category win reflects the enduring success of its patented PURe window system which features a highly-efficient expanded polyurethane (PUR) thermal barrier which offers exceptional thermal performance.

The PURe aluminium window can achieve U-values as low as 0.71W/m2K when calculated as a commercial CEN Standard window to comfortably meet the latest targets set out by Part L of the Building Regulations.

In addition to helping prevent heat loss to reduce energy consumption, the PURe system also offers ‘cradle to cradle’ recyclability, with even the PUR thermal barrier able to be reused with no requirement for landfill. Over the last ten years, Senior has continued to develop and extend its PURe range to include a variety of window styles and both commercial and residential door options.
