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.
Focused on addressing fire safety through the development and enforcement of building codes that rely on a clear understanding of the performance of plastic materials in building envelopes, NAMBA believes that performance/outcome-based testing is at the center of smart fire regulations and works to advance nationally accepted and standardized fire testing of plastic building materials and assemblies.

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 evaluations, emphasizing the importance of keeping the focus on compliance and enforcement.
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.
Building code requirements relating to NFPA 285 testing requirements and the use of the alternative materials provision of the code to extend those test results to similar wall assemblies of equal or better performance.
This infographic from the North American Modern Building Alliance (NAMBA) highlights the need for fire safety in high-rise buildings and shows how the U.S. is leading the way for facade fire testing and safety regulations.
This course assumes that the Building Designer has reviewed the building code requirements and has verified that a NFPA 285 compliant assembly is needed for the project. • For guidance on determining when a NFPA 285 compliant assembly is required, consult the NFPA 285 Compliance Decision Tree.
NFPA 285 Standard Test Method has been part of the International Building Code and previous model building code requirements for many decades. NFPA 285 is used to evaluate the suitability of exterior wall assemblies that are constructed using combustible materials or that incorporate combustible components where exterior walls are required to be non-combustible.
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.
Code requirements for specific testing are often questioned in the industry. For example, is actual testing required, or is engineering analysis permitted? Engineering analysis would fall under the category of alternative materials due to the fact that many tests are conducted as an assembly, and, therefore, any substitutions of products are labeled as alternative materials.
This article discusses engineering judgments and their use as a practical tool to assist designers and building officials with assessing the compliance of exterior wall assemblies with the acceptance criteria of NFPA 285.
This review of UK regulations examines building and fire safety regulations and related compliance and enforcement, with a focus on high rise residential buildings. This final report sets out over 50 recommendations for government as to how to deliver a more robust regulatory system for the future.
