In architecture and engineering, a joist is one of the horizontal supporting members that run between foundations, walls, or beams to support a ceiling or floor. Typically, a joist has the cross section of a plank. Joists are often supported by beams laid out in repetitive patterns.
Window headers are supports found on the upper portion of the window casing. Generally, the supports are at least twice as thick as the framing components found around the opening. The header will span horizontally across the top of the window casing, offering added support that prevents the full weight of the wall from resting on the window casing itself.
