Casement Windows

At JKG Windows & Doors, our premium casement windows are crafted in Britain using top-grade uPVC, aluminium, and timber materials, offering exceptional thermal insulation and durability. This ensures your living space remains comfortable whilst reducing energy bills and condensation on the panes.


Casement windows are available in a huge range of colours and finishes, including minimalist choices such as Cream, Black, White, and Anthracite Grey, as well as more standout RAL colours. We also give homeowners full control over the glazing and hardware, helping create a truly bespoke product. Designed with modern functionality in mind, casement windows feature advanced locking mechanisms for improved security and peace of mind.
