Classic Georgian style in modern uPVC
Sash windows slide vertically in the frame. Our uPVC sash windows combine the elegance of traditional Georgian sash windows with modern materials, making them a practical way to replace old, rotting timber sashes without losing the character of your home.
They suit Victorian and Edwardian terraces, Georgian-style houses and any property where you want a traditional look with less upkeep than painted timber.
Finishes and details
There is a wide range of finishes to choose from:
- A modern smooth finish, or a traditional woodgrain finish
- Any RAL colour
- Georgian bars to create the look you want
- Sashes that tilt inwards, so the outside of the glass can be cleaned from inside the room
Because the sashes tilt in, there is no need for ladders to clean upstairs windows, which makes maintenance much easier.
Warmer and quieter rooms
Old timber sashes are often draughty and rattle in the wind. A uPVC sash window is double glazed and thermally and energy efficient as standard, so rooms stay warmer and quieter.
If your home is listed or in a conservation area, check with your local council before replacing sash windows, as planning rules can limit the materials and designs you can use.
