Timber Sash Windows


Wooden sash windows have a bad reputation for being draughty and difficult to maintain. Whilst this might be true of old sash windows with single glazing, our timber sash windows are made from quality materials and they combine stunning period design with modern technology. At Premier Windows, our timber products are perfect for both new build and listed properties, and we have an extensive range of modern and traditional designs to choose from.

Our double glazed sash windows provide you with excellent energy efficiency. They will help you to reduce heat loss and, in turn, your energy bills. In addition to their energy-saving benefits, our bespoke timber sash windows offer unrivalled soundproofing, helping to prevent common issues with noise pollution in London. Not to mention, high-security technology comes as standard with our wooden sash windows and you can have complete peace of mind when installing them.

Premier Windows’ timber sash windows really are built to the highest specifications by our skilled craftsmen and they benefit from slim double glazing as well as a robust timber frame made from hardwood, softwood or high-performance Accoya. Our attention to detail is impeccable and we have many years of experience creating bespoke sash windows for our customers.

Modern timber sash windows are ideal for traditional properties that need replacement windows, including homes in conservation areas. All our windows are made to a high standard in line with your exact specifications and with several options available, including colour options and glazing options, sliding timber sash windows are guaranteed to add character to your property. You can even customise your new sash windows with authentic features, such as Georgian bars, sliding sashes and traditional hardware.

Sash Window Styles

We offer a range of timber sash window styles and configurations so you can be sure you’ll find the right option to suit your London home. Which style of window is best for your property will vary depending on several factors and our experts can help you to make the right choice. When replacing your existing sash windows or casement windows in London, you can choose from the following options:

Dual Swing Timber Windows
Glazed dual swing window

The dual swing window meets all the demands of today’s performance criteria and stringent building regulations while retaining the aesthetic appeal of the traditional sliding sash design. This window style doesn’t slide open, yet when it’s closed, it will look the same as any other wooden sash window.
Tilt and Slide Timber Windows

Tilt and slide windows provide 21st-century security while maintaining the kerbside appeal of a traditional Victorian building, making them perfect for installations on historic London buildings. Our Secured by Design window is what every planner has been waiting for and every burglar has been dreading.
Sliding Sash  Timber Windows
