Modular Buildings and Site Built Structures, should be built in accordance with safety in mind!
Understanding What is NFPA 285
In 1998, the National Fire Protection Association (NFPA) established the NFPA 285 “Standard Fire Test Method for Evaluation of Fire Propagation Characteristics of Exterior Non-Load-Bearing Wall Assemblies Containing Combustible Components.” NFPA 285 provides a determination of vertical fire performance for exterior wall assemblies, which is verified by actual testing. It is intended to help builders reduce the potential for upward spread of fire through wall.
The requirement for a weather-resistive barrier is as follows:
WRB (Weather-Resistive Barrier) Code Requirement: 1403.5 Vertical and Lateral Flame Propagation – Exterior walls on buildings of Type I, II, III, or IV construction that are greater than 40 feet (12.192m) in height above grade plane, and contain a combustible water-resistive barrier, shall be tested in accordance with, and comply with the acceptance criteria of NFPA 285.
For this reason, Modular Solutions, Ltd partners with companies such as DuPont™ Tyvek® air and water barriers designed for commercial construction because they have been tested and shown to meet NFPA 285, the National Fire Protection Association fire performance standard for vertical wall assemblies.
