Sliding Sash Windows

All of our Sash Windows are designed to include traditional features whilst incorporating modern operation, technology and energy efficiency. Available in all material options including PVCu, timber and timber-alternative, we have a sliding sash window to suit any home.

Crafted with attention to detail, our sliding sash windows combine the functional benefits and performance of a modern PVCu window with the feel, aesthetic appeal and operational simplicity of a traditional timber window. Our vertical sliding sash windows have a timeless elegance made with beautiful proportions and symmetry.

Our range offers a large number of feature options from authentic sash horns, deep bottom rails, traditional 22mm glazing bars and a full range of chrome or gold furniture including sash lifts, ‘D’ handles and ring pulls.
