Document Summary
In high-rise commercial construction the main purposes for partitions are: fire separation, acoustic separation. Generally in high-rise commercial construction, interior partitions are not load bearing. Due to attrition rates, systems furniture and movable walls are preferred over partitions wherever possible. Gypsum wallboard (gwb) is the most common of all fixed partition types. Its light weight does not add significant amounts to live loads of the building. Used on studs (primarily metal rather than wood), over furring to cover other rough walls or columns and on structural or suspended framing for ceilings. It can also be applied to concrete block and other substrates with mastic. Partitions are an assembly of several individual pieces.

It is light gauge, galvanized steel formed in a variety of sizes and shapes. The most common thicknesses are 25 gauge, 22 gauge and 20 gauge.
