Wood Casement Windows
(b] Casements. Casements, in contrast to sash windows, are often more in harmony with country buildings, as they are simpler and cheaper and require a less formal treatment. They are hung to stone or solid wooden frames, usually about one foot six inches to one foot eight inches apart centre to centre, and look reposeful and in harmony if arranged on the long and low principle.
In very high windows transoms are sometimes required to stiffen the mullions near the centre of their length, but they are best avoided, as they take away from the reposeful effect of the upright mullions. If they are used they should be at least six feet from the floor, so as not to interfere with the sight line.
One of the upper panes in each room should be made to open independently, so that sufficient ventilation can be effected in cold weather without opening the whole casement, or if a fanlight is provided above the transom it can be hinged at the top to open outwards.
Leaded glass is frequently used with wooden casements, but it is cheaper and quite as effective to have the small squares formed by the wooden bars as already mentioned for sash windows. Where the mullions are of stone the casements which are to open should be formed of wrought-iron or steel; and the leaded lights of those which are not to open can be fitted direct to the stonework, French casements are dealt with in Window Covering.
