Timber Sliding Sash Windows

Timber sliding sash windows

Timber sash windows are a part of British history – but you don’t have to live in a period property to appreciate them!

Timber sash windows have been a part of many properties’ facades since the Georgian period – contemporary versions can add a touch of elegance to a range of homes.

Timber sash windows do not just add style either. They offer a range of internal performance benefits for modern homeowners. This includes energy efficiency and strength – thanks to the natural properties of the wood used. This means that timber sash windows can stop draughts, retain heat within living spaces and improve the security of your home. Overall, this creates a much more pleasant living environment for you and your family.

It’s no surprise that the popularity of timber sash windows has been maintained – they last between 60 and 100 years! If fitted by a professional team, such as the installers at Keepout, they won’t need much maintenance either. Choosing our timber sash windows therefore frees up precious time that you can spend actually enjoying your house, not maintaining it.
