ABSTRACT
Figure 7.1: Casement windows made of wood are usually built in as the brickwork proceeds. They are secured with separate fixing devices, traditionally referred to as frame cramps, which are covered in detail in Chapter 6. Essentially, according to the type used,
bed joints. Two or three cramps each side is usual. Like built-in door frames, these windows, after being positioned, are plumbed and supported at the head with one or two weighted scaffold boards pitched up from the oversite or floor. If the windows have a separate sill of stone or pre-cast concrete, usually these must be bedded first and protected with temporary boards on their outer face sides and edges. Projecting sills, formed with sloping bricks-on-edge, are usually built at a later stage, the windows having been packed up accordingly to allow for this.
