How did we get to be one of the UK’s largest PVCu window and door fabricator? Based at multiple manufacturing sites across the UK, all of our divisions were originally individual businesses that through development and acquisition became the MASCO UK Window Group in 2001 which was then sold 2019 forming UK Window Group.

Then through business restructure and alignment we became UK Windows & Doors Group, and it was through this journey that transformed the business to what it is today. 



UK Windows & Doors Group incorporates ‘super fabricators’ Griffin Windows, Cambrain and Premier Trade Frames, along with dedicated glass manufacturer Techniglass, all based in South Wales. Based in Gloucestershire, you’ll find leading PVCu systems company Duraflex which has a long and distinguished pedigree in extrusion.

The most recent acquisition was Evolution, an industry leader in specialist ‘timber-alternative’ windows and doors manufacturer based in Bedfordshire. Completing the UKWDG divisions, we have our nationwide trade depot network, Sevenday Windows. These all work together to deliver a complete service offering to our customers through each of our business divisions.
