The Area Separation Wall is constructed once the framing for one townhouse unit is complete and prior to the construction of the adjacent unit. The assembly is constructed at the foundation and continues either to the underside of the protected roof sheathing or through the roof to form a parapet. The assembly is linked to the adjacent framing with aluminum breakaway clips that allow for collapse of the fire-exposed unit without collapse of the solid Area Separation Wall.
Area Separation Wall assemblies are designed for use in multi-family, multi-story townhouses as a firewall with a total height up to 50 feet. Because it is constructed using gypsum board, the assembly is easy to erect and secure, meets all building code requirements, and provides economical fire protection and sound control.
