The business is part of the wider Saveheat Group, which includes Blairs Aluminium, Merlin Network, Saveheat Glass and Blairs Windows and Doors.

Blairs has recently introduced PVC-U as a material, through its partnership with Profine UK and the Kömmerling brand, which also extends to the Merlin business.

Alex Gray, managing director of Saveheat Group, said: “Given the reputation of our brands in the Scottish market, having the right business partners is fundamental for our success in the long-term, as is the continued investment across the Saveheat Group. Kömmerling has a global reputation for being technically led and that means we can offer our customers products that have market-leading U-values for example.

“While O70 is the core of our sales, we also have one eye on the future with the Kömmerling 76 and 88mm platforms, along with their VS and WarmCore hybrid solutions which we are looking at too. While 111 years in business is an impressive achievement, with huge gratitude to everyone that has been part of this incredible journey, our eyes are now firmly
focused on the future.”

Robert Thiroff, managing director of profine UK and Kömmerling, added: “There are few companies in the industry that can boast over 100 years in the sector, though Kömmerling as a business goes back ever further to 1895. Blairs have stood the test of time across all window and door materials and as our ScoOsh business partner, we are hoping for many
more years together through the promotion of a complete range of window, door and building systems.”
