Vertical Sliding Sash Windows

The vertical sliding sash window has been a feature of British housing for several centuries. At Glazefix we have improved and updated the design, not only do our replacement UPVC Sash Windows slide up and down but both inwardly tilt for ease of cleaning and ventilation.


The beautiful sculptured frame, bead and Georgian bar of the sash window fully integrates with our full range of UPVC windows so you can mix and match styles throughout your home with confidence.


Vertical sliding sash windows combine modern technology with traditional design and character, giving you a stylish window that doesn’t compromise comfort and security. Glazefix UPVC sash windows provide excellent thermal and weathering performance and the tilt-in facility allows for easy maintenance.


The elegant conservation grade vertical sliding PVCu sash window from Synseal provides all the benefits of period charm while retaining the high technology of PVCu at a cost-effective price.
