Sliding Sash Windows

Designed to replicate period-style timber windows, making them ideal for heritage homes and conservation areas

Sliding Sash Windows

Sliding sash windows are vertically opening windows that consist of one or two movable panels (sashes) which slide up and down within the frame. They are commonly associated with Georgian, Victorian, and Edwardian architecture and are valued for their elegant proportions and traditional appearance.

Modern versions, especially those made from uPVC combine this classic style with contemporary benefits like energy efficiency and low maintenance.
