Foam sheathing can be used in a variety of buildings and assemblies requiring fire resistance, where properly tested. Below find resources for using foam sheathing in fire rated applications.

Top Resources for NFPA 285 Compliance using Foam Sheathing:

 

Tools & Education

NFPA has developed this free interactive tool to help navigate the code requirements that apply to exterior walls containing combustible components. It also helps determine when those requirements apply for testing to NFPA 285.

Identifies the products supplied by FSC members who have code evaluation reports showing compliance with NFPA 285 testing requirements. 

In view of international fire events, this flyer examines U.S. codes and standards (IBC and NFPA 285 requirements) as well as the practice of engineering judgements, emphasizing the importance of keeping the focus on compliance and enforcement.

Best Practices

Foam plastics used in buildings of Types I-IV construction require an assessment of their ability to resist vertical and lateral flame spread. Determine if your assembly is required to comply with NFPA 285 Fire testing with this decision tree.

Practical Research

The fire at London's Grenfell Tower in June is prompting many facilities and communities to order more sprinkler systems for high rise residential buildings.

Concerns about fire safety at Grenfell Tower had been ignored, including lack of a working fire alarm system or sprinklers. 

Contains excerpts from various news sources that make the case that sprinklers would have saved lives had they been installed in Grenfell Tower.

Re-examining fire safety in light of tragedies such as the Grenfell fire yields a few lessons for the U.S. market. Strictly conforming to the IBC can help builders and designers provide the best engineered, economic and safest solutions.
