Glazing bars, beadings and sash Horns.
Glazing bars and beadings for sliding sash windows can be ordered as standard or can be designed, manufactured based on the customer’s individual specifications and requirements. As standard Wood And Home offers 4 or types of beadings. The most popular vertical or horizontal bar is “astrogal” which come in standard 25mm width.
The height of glazing bars depends on the double glaze unit thickness. For instance, when a 20mm double glaze unit is fitted the height of beading is reduced to maximum 15mm, in turn reducing the thickness of glass can help to achieve better mouldings.
Horns can be added to sashes both internally and externally, depends on client requires. We offer 4 standard types which are most common in Victorian windows.

TIPS while taking measurements for box sash window!
It has been recommended for new sash windows to allow for a 84mm frame jab, and for frame jambs to be placed on each side and inserted into the wall and in turn which allows the sash cord mechanism to be covered. Regarding the external view, it has been suggested that we allow a 20-30mm of the visible to be facing, whereas the rest is hidden.
During new openings, when the catnic lintels are installed the facing frame-head can be reduced from 84mm to 40mm (it is the frame’s minimum thickness of sliding sash windows). From an external point of view, the overall framing will look symmetric.
