Box Sash Window

The modern day version of the classic Box Sash Window otherwise known as the double hung sliding sash.

This window uses cords, weights and pulleys to counter balance the sashes in the traditional way with the weights housed in a box created by the internal and external liners over sailing the frame on each side. Typically this 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 and architrave.

The Box Sash is equipped with our patented click fit staff and parting bead which allows the sliding sashes to be easily removed for future maintenance and decoration.

The entire Conservation range is suited to offer a common choice of frame profiles and glazing bars along with a variety of double Glass unit depths and specification to ensure that your aesthetic, thermal and acoustic requirements are achieved.
