Decorative Horns
Horns are included to the upper sashes on Allan Brothers sliding sash windows

Frame Soles
Windows are supplied with flush soles as standard. 25, 47, 62 and 87mm timber sole extensions are available on request. Please note that, in the event of windows in a reveal situation requiring a sole extension, the amount that the extension will need to be cut back from each end of the window to the depth of the reveal should be clearly specified.
Timber
As standard, the frames and sashes are made from quality redwood. However, they can, on request, be made from hardwood.
Cases
As standard, the windows are supplied with 95mm wide inside facings and 56mm outside facings (41mm from daylight) forming an open pulley box to suit reveal openings.
Boxed mullions with continuous head and soles, 153mm wide to suit 6 inch imperial stone mullions, are standard, although wider ones can be made to order.
Alternatively, if required for straight-through openings, windows can be supplied with 110mm wide outside facings (95mm from daylight) and external mullion plates. Note: a solid frame construction is adopted when spiral balances are fitted, in lieu of the above boxed frame construction.
