DOORS, Framed, which are either single, folding, double, or double margin, are employed in all descriptions of build ings, and consist of styles, rails, panels, and, in most cases, of munitions also. The framing includes all the parts but the panels, and is held together with mortices and tenons. The styles are the vertical parts of the framing at the sides. The rails are the horizontal pieces, tenoned into the styles. Munnions are parts of the framing, tenoned into the rails. The panels fill up the holes left in putting the framing together, and are let into grooves cut in the internal edges of the styles, rails, and munnions. Doors are generally framed in rectangular compartments ; though other forms, as circles, ellipses, lozenges, &c. may be adopted, according to the fancy of the proprietor, or the taste of the builder. Framed doors are either square or moulded ; the former are used only in common houses. Mouldings are of various forms, some confined within the framing, and others propet ing beyond it. The mouldings and form of the panels of the door, generally regulate those of the window-shutters.
nz Folding doors, or doors of comun i icalion, are made n two breadths, and have a pair of styles to each leaf.
The Building Act (7 and S Viet. cap. 84) requires that open ings through party walls be secured by wrought-iron doors.
" Such openings must not be made wider than six feet, nor higher than eight feet, unless in each ease, and upon special evidence of necessity for convenience or otherwise, the official referees shall previously authorize larger openings.
" And the floor, and the jambs, and the head of every such opening, must be composed of brick or stone, or iron work throughout the whole thickness of the wall.
"And every such opening must have a strong wrought iron door on each side of the party wall, fitted and hung to such opening \\ ithout wood-work of any kind ; and such doors must not be less than one-fourth of an inch thick in the panels thereof.
"And each of such doors must be distant from the other not less than the full thickness of the party wall." Double doors are contrived to close against each other, in opposite directions, the one opening outwards, the other going inwards, in order to keep the apartment warm : the inner door being covered with baize.
woryin doors, are single doors, with a broad piece running vertically down the middle, called the imitating the two internal styles of !biding doors when shut.
Whatever kind of door be adopted, it should, for the sake of uniformity, be used in all the apartments of the same story.
