- Abstract
- This report presents the temperature measurements from 5 full-scale fire resistance tests conducted at the National Fire Laboratory on insulated and non-insulated full-scale gypsum board protected wall assemblies. Asymmetrical gypsum board installations 1x2 (one layer of 12.7 mm thick gypsum board on the exposed side and two layers of gypsum board on the unexposed side) on light steel studs were evaluated. The insulations used were glass, mineral and cellulose (wet sprayed) fibers. Tests were conducted to determine the effects of the insulation type in the wall cavity and the insulation tightness between the studs on the fire resistance rating of gypsum board wall assemblies. The temperatures measured on the gypsum board surface and on the studs are presented.
