- Abstract
- This report presents the temperature measurements from 7 full-scale fire resistance tests conducted at the National Fire Laboratory on non-insulated, loaded and non-loaded, regular gypsum board wall protected assemblies. Assemblies were 1x1 (one layer of gypsum board on both the exposed and unexposed sides) using wood studs and 2x2 (two layers of board on both the exposed and unexposed sides) using lightweight steel and wood studs. Three regular gypsum boards with different masses per unit area were evaluated: 7.82 kg/m² with no glass fiber in the gypsum core, 7.35 kg/m² with glass fiber in the gypsum core and 7.27 kg/m² with no glass fiber in the gypsum core. Tests were conducted to determine the fire resistance rating of the assemblies. The temperatures measured on the gypsum board surfaces and on the studs are presented.
