Casement Windows

A Typically English Style

‘Casement windows’ are simply defined as a style that is being hinged on one edge, enabling a window to open to a far greater percentage than a sliding sash style unit.


All casement windows installed by TWG are easy to operate and are available in a variety of configurations and manufactured with security in mind including internally beaded so preventing glazing being removed from outside the building. When closed casement windows will seal better than many other window styles preventing draughts and can be more secure than sliding windows as hook locking mechanisms are restricted by sliding sections.


As a uPVC Casement window installer we ensure our casements windows are now fitted with A rated energy efficient glazing and warm edge spacer bars are as standard. Each window is bespoke to your property and our surveyor* will measure and help guide you through options such as openings and hardware.


And as with all TWG fully installed items we offer a 10-year insurance backed guarantee* and you also receive the added home-owner benefits of purchasing via a registered FENSA member.
