A blend of old and new with uPVC sash windows

Our uPVC wood effect sliding sash windows accurately replicate traditional timber joinery techniques for an authentic sash window appearance. However, they offer a maintenance-free life, exceptional durability and other performance benefits associated with high-quality uPVC.

uPVC sash windows retain vast quantities of heat thanks to an innovative multi-chambered window profile that is designed to trap heat inside the home whilst keeping the cold out. Thanks to fully reinforced steel sashes, they are capable of achieving ‘Secured by Design’ accreditation, so the security they provide for the home is truly outstanding too.
