KAT uPVC Casement Window

Quality uPVC Casement Window designed & manufactured in the UK

Flush timber casement windows have been around since the 19th Century. Every Knightsbridge uPVC window is hand finished and has all the visual attributes of traditional joinery, but with high levels of security and energy efficiency. They are a credible alternative to wooden flush casement windows with the advantage of being almost maintenance free.

The aesthetics of your window can be enhanced by adding Georgian bars to complement the architectural style of your property.
