Fire-resistance protects lives and property.
Area separation walls are nonload-bearing, 2-hour
rated vertical wall assemblies that provide fire-resistant
protection between adjacent living units in apartment
buildings, condominiums and townhouses. They are also
referred to as party walls, firewalls, multi-family walls and
H-stud assemblies.
Assembled between two independent walls, area separation
walls form a commonly shared party wall that extends
from the foundation through the roofline. The walls are
assembled with two 1"-thick gypsum panel liners vertically
installed between 2" H-studs spaced 24" o.c. At the top
and bottom of the walls, C-runners (or H-tracks) are
installed back-to-back between vertically stacked panels.
Overall stacked area separation wall assemblies cannot
exceed 50 feet.
A photo of an area separation wall system after a fire is
shown below. Although this was a tragic event, it clearly
proves the eectiveness of the system. It performed
as designed by maintaining the integrity of the firewall,
protecting the lives and property of the adjacent units.
