Classic but functional Sliding Sash Windows from T&K Northampton, Northamptonshire, Milton Keynes, Rothwell, Wellingborough, Corby, Kettering and Rushden

For many period properties there's no other sensible choice and for all of us there's the convenience of a window that slides inline, rather than opening in or out.

Our latest range uses specially designed steels to enable window sizes of up to 1600mm by 3000mm. Strong side tracks and cross-bars ensure the window stays square and slides effortlessly every time.

Locks conform to the Police's Secured By Design standard and security's further enhanced by an aluminium security bar that blocks the tracks when engaged to prevent the window being levered.

The overall result is a beautiful, sturdy window which, until just a few years ago, would have been priced very much at the premium end of the market. Our latest products change all of that.
