DOUBLE - HUNG WINDOWS
Meeting Rail Strength
Meeting Rails: The limiting strength factor on double-hung windows without lowlights will be the strength of the meeting rails or the mullion if applicable.
The tables below show the strength of meeting rails on a range of window sizes.More detailed information is contained in the
Specifier Manual.
Transoms: On wide frames fitted with overlights (transoms) the transom will in most cases be the weak link. Refer following page for transom options.
For a stronger heavier double-hung window go to Magnum™ Double-hung window section.
