Gypsum wallboard is among the much more prevalent lining materials for walls and ceilings used for design of residential and commercial facilities.
Madrzykowski and Fleischmann (2012) done a study on the reaction of gypsum wallboard as well as the reproducibility on the hurt sample developed when subjected to recognized heat launch level (HRR) fires with various different types of fuel sources and wall development. The fuels made use of for their experiments incorporated a pure fuel burner, gasoline pool fire and polyurethane foam. The wall construction was different involving only one sheet of gypsum wallboard with wood framing, a gypsum wallboard front and back with wood framing and gypsum wallboard front and back with fiberglass batt insulation while in the voids of the wood framing.
