Dressed shingles are commonly painted. Their form may be as ornamental as desired. Outside shingles are sometimes laid five and one-half inches to the weather, but four and one-half is better. It is not uncommon at this time to leave all shingles unpainted and unstained. The effect is very agreeable when they become weather-stained.
All horizontal trimmings and casings should be bevelled on the top to shed the water. They should run back under the shingled weather-boarding or other outside covering. There should be tin covering for all projections in excess of one and three-eighths inch. Ordinary window or door casings outside are usually three-eighths inch thick.
All windows in the part of the house regularly occupied should have box frames. Pulley styles should be of hard wood, and the inside bead should be secured with round-headed screws. Sash for plate glass should be one and three-fourths inch thick; side rail, two and one-half inches in rabbet; bottom rail, three and one-eighth inches; and meeting rail, one and one-fourth inch in the rabbet. Sash for common glass may be one and three-eighths inch thick. Other sizes, as given. Sash, for rooms finished in hard wood is better when of the wood in which the room is finished. However, where there is great variation this is not necessary. Quartered oak is the material commonly used for hard-wood sash. Almost any hard wood is more liable to warp than pine. All box frames should be provided with turned axle pulleys. Nothing but the best plaited cotton sash-cord should be used. Necessary weights should be provided.
In some of the plans where wide front windows are indicated, the design is called pocket head. There is a pocket above the head of the frame so that a high sash may be run into it. The sash may be pushed up into the pocket; that is, it runs into the wall above the head of the frame. Where the pocket-head window is used, it is necessary that there be a clear space above the frame for the sash to be run up equal to the height of the sash itself.
Hinged or pivoted windows have rabbeted frames which are usually one and three-eighths inch thick. They are used for the most part in unfinished cellars, attics, and unoccupied parts of the house, and preferably for pantry, store-room, and, occasionally, bath-room windows. They may be hung on hinges or pivots. Hinges are better, for the reason that fly screens cannot be used where the sash is pivoted. Sills should slant twenty degrees, with drip piece secured to outside. This prevents the storm from blowing water to the inside.
