High-performance timber/ wooden vertical sliding Box Sash Windows with period sightlines and details.
Suitable for any residential, commercial properties and conservation areas.
The modern day version of the Vertical Sliding Box Sash Window otherwise known as the double hung sliding sash. This vertical sliding sash uses cords, weights and pulleys to counterbalance the Sashes traditionally with the weights housed in a ‘box’.
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.
Colours from the RAL classic range, colour matching and stains also available.
Timber: 30; Glazing, ironmongery and seals: 10; Paint finish: 10; Stain finish: 5.
