Fig. 24 The Solid Brick Wall
Window sills in brick buildings should be of brick or stone. Cement, unless pre-cast, is not well adapted for the purpose. Brick window sills are preferable to stone for, besides adding a charming touch to the building, they are inexpensive since they are of the same material as the wall and placed by the same workmen who lay up the wall, thus obviating the necessity of additional labor to place the heavy stone. Brick for sills should be laid on edge and pitched approximately at an incline of 1 inch in 6 to shed the water. They should also project at least an inch beyond the face of the wall to form a drip, and be laid in rich cement mortar composed of equal parts of cement and sand, with joints well filled and finished with a hard smooth surface. Door sills may be of wood, brick, or stone. In case of a stone sill, it should be exactly the height of either two or three courses of brick.
Window Frames
The window frames are set by the carpenter on top of the sill in a thin bed of mortar. When they are leveled, plumbed, and braced, the brickwork is carried up around the jambs or weight boxes, as shown in [Fig. 24], always making certain that the corner or jamb of the brick opening is perfectly plumb. Great care should be taken to fill solid with mortar the spaces between the brickwork and the window frame, to stop the wind.
