This article deals with problems associated with a thermal barrier material called Thermo-Lag 330. Typically in nuclear applications this material is used to provide either 1 hour (1/2 inch thick) or 3 hour (1 inch thick) barriers to prevent the spread of fires between redundant safety systems, and to protect cable trays and conduit. The article reviews concerns within the nuclear industry as to the proper handling of the material, how to interpret the data available on the material, the apparant conflicting assessments of the material when tested by different groups, etc. Research is ongoing on the suitability of the material, but the article points out that the manufacturer feels it should be installed by properly trained installers, the joints sealed with a grouting material, properly bundled to maintain its integrity, have a complete stress skin, and not be walked on after installation in order to function properly.
