Sash Windows
Sash windows give your home that timeless period look, with one or more panels that slide vertically to open. Through Help 2 Buy Windows, you could get modern uPVC or timber sash windows that keep all the traditional charm while adding the warmth, security and energy efficiency of modern double glazing.
What are sash windows?
Sash windows are made up of one or more movable panels, called sashes, that slide vertically within the frame to open and close. They are a defining feature of Victorian, Georgian and Edwardian homes, prized for their elegant proportions, slim sightlines and classic period detailing.
The trouble with original timber sash windows is that they rattle, stick, let in draughts and do almost nothing for your heating bills. Modern sash windows solve all of that. You keep the authentic look, with run-through horns, astragal bars and traditional furniture, while warm-edge double glazing sits hidden inside the frame.
You can choose virtually maintenance-free uPVC for the practical option, or timber for the most authentic finish. Either way, you get a draught-free, secure, A-rated window that respects the character of your home and finally keeps the heat where it belongs.
Styles, colours and options
Every sash window is made to measure, so you can tailor the finish to suit your home.
- ✓ A full range of colours, including classic heritage white and cream, plus on-trend anthracite grey for a sharper, contemporary look.

Sash Windows FAQs
What are sash windows?
Sash windows are made up of one or more movable panels, known as sashes, that slide vertically within the frame to open and close. They are most often associated with Victorian, Georgian and Edwardian homes, and are loved for their slim sightlines and elegant period proportions. Modern versions use double glazing for far better energy efficiency than the draughty originals, while keeping that authentic traditional look.
Can I get double glazed sash windows that still look traditional?
Yes. Modern uPVC and timber sash windows are designed to replicate period detailing such as slim sightlines, run-through sash horns, astragal bars and authentic furniture, while hiding warm-edge double glazing inside the frame. You get the heritage look from the street and far better warmth, security and quiet inside.
Are uPVC sash windows allowed in conservation areas?
It depends on your local authority and whether your property is listed or in a conservation area. Many heritage-style uPVC sash windows are designed specifically to meet conservation requirements, but you should always check with your local planning department before ordering to make sure your chosen style is approved.
Do sash windows need a lot of maintenance?
Modern uPVC sash windows are virtually maintenance-free and only need an occasional wipe down to keep them looking their best. Timber sash windows give you the most authentic finish but will need periodic painting or treatment to protect the wood and keep them working smoothly.
