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

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.

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