Course Description: AEC Daily: Two-Hour Fire-Resistance-Rated Walls
Single-family attached residences (residences that share one or more walls between neighbors) are required to utilize area separation walls between units. A key design criterion of any firewall—besides its fire rating—is that it be structurally independent in a fire. This course evaluates two-hour fire-resistance-rated walls used in single-family attached and multifamily residential construction, the options available in today’s marketplace, firewall installation requirements, and fire-resistance testing.
Define the single-family attached residence and explain the factors driving its market growth.
Discuss why the design and construction of a firewall mitigates the spread of fire and protects the building occupants.
Identify five types of two-hour firewalls and compare their design considerations and installation requirements.
Describe the UL U370 assembly, list the benefits of using it, and specify the requirements of the assembly as a fire separation wall.
Summarize the UL U370 assembly fire-resistance testing methods and results.
Review firewall construction in single-family attached residences in terms of compliance with the International Building Code.
Analyze the risk management process and quality assurance measures pertaining to firewall installations.
