Timber box sash windows
Operated using weights and pulleys the sashes can be hung using pre tensioned nylon cords or chains for long lasting reliability.
Crafted using slow grown knot free engineered timber our box sash windows are extremely durable and resistant to twisting and warping. Backed by a reassuring 30 year warranty against rot and fungal decay the construction of our timber sash windows is built to last the test of time with smooth operation for many years to come.
Our unique concealed triple weather strips add to the traditional feel whilst eliminating any drafts into your home in the winter months.
Also available in slim form we can provide the slimmest box sash window in the UK. Measuring only 142mm front to back our Slim Box Sash is an ideal replacement for original single glazed sash windows which are typically slimmer than modern double glazed windows. This allows us to replace your windows without intruding into the room. The Slim Box Sash takes advantage of high insulating levels provided by krypton gas used in our slim double glazed units.
