Whereas many uPVC windows are prone to warping and cracking, our selection of modern uPVC casement windows will never rust, crack, warp or rot, leaving you to enjoy an extremely cost-effective window option.
You won’t have to worry about excessive amounts of maintenance or upkeep. What’s more, uPVC is extremely easy to clean, meaning that if they should ever become dirty, a simple wipe down with a damp cloth will do just the trick.
The new windows have been stringently tested to ensure that they keep their sleek look for several years. Manufactured using high quality uPVC, you can be sure that you’re investing in replacement windows that offer superior standards of efficiency.


At Jack of Glass, we offer a range of beautiful colour options that are guaranteed for 10 years as standard. Some of the shades we offer for our casement windows include traditional white, light oak and rosewood.
Whether you’d prefer a design that is more subdued or bright and bold, we can help generate replacement casement windows that are perfectly suited to your needs and match the style of your High Wycombe home.
As well as the colour, you also have the option to adjust the sizing, hardware and glazing of your new windows. This allows you to generate a completely bespoke set of windows that match the existing architecture of your property.
