Mill Steel Framing is a licensed manufacturer of the USG Area Separation Wall Systems. USG area separation wall systems are lightweight, non-load-bearing gypsum panel partition assemblies used to provide fire-resistive protection for common walls in townhouse construction.

These systems install quickly and easily. Because they weigh at least 50% less than masonry walls, installation proceeds rapidly. In addition, use of these assemblies gains valuable floor space for the building interior, because thickness is 3-1/2” compared to 8” to 12” for a masonry wall without interior finish.
