The spring sash window is a modern day alternative of the cord & weighted box sash window. It uses a concealed spring loaded mechanism instead of the cords, weights and pulleys found in a traditional sash window, this has the advantage of allowing for a smaller structural rebate or installing into a flush reveal.

Our Conservation Box Sash Window uses cords, weights and pulleys to counter balance the sashes in the traditional way. Typically a Box Sash Window would be set back in a ‘rebated reveal’ construction so that the box is mostly hidden by the external brick or stone although it can also be seen positioned close to the face of the brickwork with the box on show and dressed with an architrave.

We also have a choice of 40,000 colours and a wide range of ironmongery so you can be sure your vision can become a reality.
