Wall Fire Experiments Examine Exterior Fire Spread Changes

In April 2013, 28 different wall fire experiments were conducted, which included the following:

• 8 ft. by 8 ft. wall assemblies with siding, sheathing, studs, insulation, and gypsum wallboard were burned.
• A 25-200 kW burner was used to ignite the wall assembly.
• Two experiments used grills for ignition.
• Measurements Included: Heat release rate, heat fluxes 6 ft, 12 ft, and 18 ft from the wall, and temperatures under the siding and temperatures in the wall cavity.
