PROCESS FOR PRODUCING PARTS OF WINDOWS AND DOORS

摘要

The frame member (5) has an outer side (1) and an inner side (2). They are connected by portions, one of which (3) is in contact with the glass of the windowpane and the other (4) is in contact with the brickwork of the wall. There are two partitions (8,9) between the glass-side and wall-side frame portions, and the space between them may be filled with steel reinforcement (10). There are air gaps between the inner and the outer side frame portions and the partitions.
