All sizes are from centre of mid-rail to edge of outer frame. All door and side-screen combinations with low threshold (aluminium or UPVC) will be made separately.

Open out door and side-screen combinations will also be split as there is no ‘Z’ section for the wide mullion – you can have the side-screen externally beaded and the door sash internally beaded and still make the item in one if you wish, but this will need to be stated on the order.
