- Abstract
- The paper describes experimental measurements conducted at the National Bureau of Standards to compare the thermal performance of three different insulating materials commonly used to retrofit the exterior frame walls of existing residential buildings. The insulation materials selected for study were cellulosic fiber, fibrous glass wool, and urea-formaldehyde foam. The thermal conductivities of the three materials were measured using the guarded-hot-plate apparatus according to Standard Method of Test ASTM C 177-71. Heat-transmission and moisture measurements were performed on a full-scale test wall that was exposed to simulated winter conditions in the laboratory. Similar measurements were also conducted on wall sections of a test house insulated with the various materials. Other performance properties such as shrinkage and settling are also reported.
