What is a timber sash window? +
The sash window has been popular in Britain since the 17th century and was the most common style during the Victorian, Regency and Georgian periods. It comprises two sashes that slide up and down — an inner and outer sash hosted within a channel — and can open at the top, bottom or both. To achieve the heritage look, Schnauber uses a double glazed unit with Georgian bars applied on top of, between and inside the glazing. Available styles: spiral balance, cords & weights, and Heritage Slimlite.
Where would I install a timber sash window? +
Sash windows suit any room in your property. Ideally the window should be bigger than 90cm × 60cm — for the most attractive results we recommend a size over 1.1 metres.
Why would I choose timber sash windows? +
If you live in a Grade I or II listed building or one of the UK's 8,000+ conservation areas, timber sash may be required — always check with your local Conservation Officer. They're also a defining feature when renovating Georgian, Regency or Victorian properties, and ideal where something in front of the window (like a sink or bath) makes an outward-opening casement impractical.
What options are available for my wooden sash windows? +
A choice of hardwood and softwood engineered timber finishes, depending on budget and visual specification. Historically painted white, but the selection of colours is unlimited — plus a wide selection of glass types and ironmongery.
Are Schnauber's timber sash windows environmentally friendly? +
Yes — all our wooden windows are manufactured from responsible, sustainable sources certified by the Forest Stewardship Council (FSC), with the latest water-resistant paint finishes.
How long will it take to install new sash windows? +
One sash window takes our team a day to install, including all architraves and finishing touches.
How easy are sash windows to maintain? +
Generally easier than casements — fewer moving parts means less to go wrong. Schnauber windows are pre-treated with a non-toxic wood preservative, so maintenance is minimal: we recommend every 5–10 years depending on your environment.
Schnauber's top tips for timber sash windows +
Sash windows are a safer option than casements if you have young children, and ours include an additional safety feature offering greater protection against burglary. Aesthetically, you can't tell the difference between a traditional single-pane sash with Georgian bars and our Heritage Slimlite with separate panes.
What should a replacement sash window survey record? +
Record the opening size, sash proportions, glazing-bar layout and any original mouldings to retain. Discuss cords-and-weights or spring balance and the glazing options. If the building has heritage controls, check the proposed work with the relevant authority before ordering.
