Casement Windows

Casement Windows from Grabex

Incredibly versatile and high performing windows in variety of styles, colours, sizes and materials. Timeless, and effortlessly practical—there’s a reason why casement windows are so popular with UK homeowners.

Offering one of the most cost-effective solutions thanks to the simplicity of their engineering, they’re used across a huge range of building styles. These windows offer excellent security and insulation, as well as the versatility of fitting with an array of architectural styles, from period properties to modern dwellings. Flush casements are often found in neo-Georgian homes, while rebated versions are used across a variety of builds, either in timber, PVCu, aluminium or composite frames.

They can be incorporated into both renovations and new builds and generally come at a lower cost than sliding sashes or other modern configurations. Nowadays, thanks to the high performance products available, it comes down to personal choice. Flush casements lend themselves to older, pre-war properties as they are more of a traditional style window, supplied in imperial sizes, and sit flat to the frame.
