Does your project require NFPA 285 Compliance?
Since Stonewood offers three types of fire resistant panels: Class A-285, Class A, and Class B it is vital the NFPA-285 requirements be determined EARLY in the project specification process in to order avoid project delays.
This quick decision-making chart will help guide you to the best Stonewood panel solution for your project.
Disclaimer: *NFPA 285 compliance may be required due to local build codes, design requirements, or other items outside the above specified requirements. It is the responsibility of the “Authority Having Jurisdiction” (AHJ) to verify the final wall assembly meets stated NFPA 285 installation requirements.

What is NFPA 285?
NFPA 285 is the standardized procedure for fire testing of exterior walls when combustible materials, such as foam plastic continuous insulation, panels, and water-resistive barriers (WRBs), are components within the wall assembly.
The stringent test provides a specific method of determining the flammability characteristics of complete exterior, non-load-bearing wall assemblies/panels. Designed to emulate the actual fire-resistance performance of the wall assembly in a constructed building, NFPA 285 evaluates combustible components within wall assemblies for buildings required to be of non-combustible construction.
