Casement Windows

Colin's Sash Windows supply casement windows using Kommerling Chamfered C70 and Ovolo O70 sculptured profiles. Profiles offer a 70mm frame depth, extruded using a lead-free colourfast UPVC Greenline compound. The ovolo design of the O70 has a curved frame and opening sashes creating a softer appearance adding design flair to your installation. The C70 gives a clean modern look with its chamfered design.

Our affordable casement windows are using all the privileges of Kommerling:

  • Highest quality materials;
  • Long and successful track record;
  • Satisfaction guaranteed;
  • Warranty for every part of the window;
  • Lower prices.
We supply windows directly from the manufacturer and we are able to offer them at trade prices. We are also environmentally-conscious – all our casement windows are rated ‘A’ in terms of energy efficiency. Getting one of our products is among the best ways to save money on energy bills in the long run.

Features of our Casement Windows

We use Swisspacer spacer bars for optimum warm edge and reduced condensation and Planibel A glass for optimum energy efficiency. We also offer a range of Pilkington glass products such as Optiwhite for premium visibility, and Activ self cleaning glass.
