. Cyclopedia of architecture, carpentry, and building; a general reference work ... ng, such as a window^ or a door,the outside finish, consisting ofshingling, clapboarding, or othercovering, has to be cut through,and if no special provision weremade for the finish around theopening there would be as aresult a very ragged order to avoid this it is cus-tomary to place all around thewindow opening pieces of finishedtimber which are known as out-side trim, outside architrave, oroutside casing. These pieces forma stop for the wall covering. Fig. 304 shows a window opening in elevation looking from theoutside and showing the outside trim. At A is shown the casingaround the sides and head of the window and at B is shown the Fig. 305 is shown a section through the sill at the outside of thewall. Here, A is the sill itself which extends through the wall tothe inside and receives the sash as will be explained later; B is therough framing for the opening and this piece goes between the verti-cal studding at the sides of the rough opening; C is the outside. Fig, 304. Elevation of Window ShowingOutside Trim 229 218 CARPENTRY boarding attached to the studding; D is the wall covering of shinglesor clapboards; and E is building paper which must be placed betweenthe outside boarding and the wall covering. It will be noticed thatthe under side of the sill is ploughed to receive the shingles or clap-boards and that it projects out over the wall line a distance of about1 inch, so as to let rainwater drip to the ground without touchingthe wall. This figure shows the simplest sort of sill, such as wouldbe used only for very cheap work. In more important work it iscustomary to add another piece, called an apron, under the pro-jecting part of the sill, as shown in Fig. 306, where A is the apron,B is the sill, and C is the wall covering. The purpose of the apronA is to cover the joint between the wall covering and the sill and togive it a finished appearance. Fig, 307
