Our Heritage Box Sash window is designed to replace original period windows found in listed buildings and in sensitive conservation areas where double glazed products are not appropriate, and where full compliance with modern Building Regulations is not required. The Heritage Box Sash window is single glazed in the traditional way, using putty and true glazing bars, which are available in a variety of glazing bar sizes and profiles including Gothic, Victorian, Lamb’s Tongue and Queen Anne Ovolo.
The Heritage Box Sash window is manufactured using slim frame and sash sections and operated using cords, weights and pulleys to counterbalance the sashes. 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 visible and dressed with an architrave.
The Historic Box Sash is supplied with one coat of primer only. The remaining top coats are to be applied on site by others. The glazing putty must be left to cure for at least two weeks once the product has been installed before painting.
All timber framing is meticulously prepared for painting by state of the art machinery before the primer coat is applied.
Typically in RAL 9003 Signal White but our customers may choose from the RAL Classic swatch.
On request we are able to offer a colour matching service.
We are able to offer a ‘dual finish’ where different colours are desired internally and externally or a ‘mixed finish’ where frames are specified to be contrasting to sashes.
Our Heritage box sash windows are traditionally glazed with single panes of glass using glazing compound (putty) which hold the glass in place.
