uPVC Vertical/Sliding Sash Windows
Choose from three timeless collections.
elegance & style
Vertical/Sliding Sash Windows that are maintenance-free.
Our uPVC sliding sash windows are incredibly low-maintenance, with no warping or twisting to worry about. Aside from the occasional wipe-down, you only need to enjoy the added safety and security, double glazing, and energy efficiency they provide.
They have all the features that give them an original charm – white woodgrain finishes, deep base rails, surface-mounted Georgian bars and run-through sash horns.
