Transforming Homes Across Teesside

Whilst most window manufacturers and installers use an outdated 3 chamber profile, our UPVC windows have a patented 5 chamber profile, allowing for an increased thermal performance. This feature is one of the main reasons that our windows are much more efficient than our competitors. Our windows have soft sculptured lines in the frame and sash, and low line gaskets that help to achieve a much slimmer sightline. As standard, all our windows are supplied and fitted with the following:

  • A profile depth of 70mm
  • A 5 chamber profile, allowing increased insulation
  • Reinforced profile
  • Finished in a choice of 44 different colours
  • Higher security from internal beading
  • 25 year colourfast guarantee
