Fire Protection of Lightweight Framing Floor Assemblies

1/12/2021 1:00 PM - 2:00 PM

Instructor: Robert Kuserk (APA – The Engineered Wood Association)


Link to Webinar:


This program identifies the features and benefits of wood I-joists which explains the prevalence in the market. The program also explains UL fire testing that identified the fire performance failures or light frame floor assemblies which led to changes in the floor protection requirements of the International Residential Code (IRC). Those IRC protection requirements are explained. Alternate methods of protecting I-joist assemblies per ICC-ES Acceptance Criteria AC14 are explained along with the details of acceptable installation of specific assemblies. A statewide survey of fire marshal is reported to give attendees a sense of peer consensus on acceptable methods of protecting wood I-joist floors.

Learning Objectives

  1. Identify features, benefits and fire safety challenges for wood I-joist construction.
  2. Explain results of a statewide fire marshal study on wood I-joist and protection awareness.
  3. Identify methods to protect engineered wood construction to safeguard public and first responders.
  4. Identify independent agency reports that evaluate protection equivalencies.
