uPVC sash windows


Vertical sliders are a classic window design. They are commonly found in older homes and are usually made of wood. This elegant type of window is a common replacement in period homes, its design adding a sophisticated elegance and style to your home that a regular casement window cannot. Because real wood windows can be costly, homeowners prefer less expensive alternatives such as uPVC.

uPVC sash windows are thermally efficient and environmentally friendly, emulating the elegance of a classic timber vertical slider while providing all of the advantages of a modern uPVC device, giving you the best of both worlds. Whether you live in an older or newer home, uPVC sash windows are a cost-effective option for replacing like-for-like or as an alternative to other models.

Splay and 90° bay models are also available. Choose from a variety of colour and hardware options to finish your window and build a look that is exclusive to your home.
