This report details a project undertaken in 2006 and 2007 to verify the fire rating of gypsum wall/steel stud assemblies. Samples were sent to six different fire testing laboratories and tested in 10 different furnaces. All of the laboratories returned ratings of 1-h for the samples. Researchers measured the thermal conductivity and specific heat of the gypsum wall samples at room temperature. Measurements were taken with both the paper in place and ...
Intumescent paints protect steel structures from fires by creating insulative foams when heated above a critical temperature. This paper examines the fire resistance capabilities of phenyl silicone coatings in comparison to intumescent paints. A thermal constant analyzer measured the thermal conductivity of the silicone-based coatings using the transient plane source (TPS) technique. Results showed that the silicone/modifier coating consistently had lower thermal conductivities than the silicone coating. At heightened ...
