Thermal resistance of composite panels containing superinsulation and urethane foam

PDF Version Also Available for Download.

Description

Laboratory data are presented on the thermal resistance of composite panels that incorporate superinsulation embedded in urethane foam. Composite panels were fabricated using four types of advanced insulations (three types of evacuated panel superinsulation and one type of gas-filled panel), and three foam blowing agents (CFC-11, HCFC-141b, and HCFC-142b/22 blend). Panels were also fabricated with only the urethane foam to serve as a baseline. Thermal measurements were performed using an ASTM C 518 Heat Flow Meter Apparatus. The thermal resistances of the panels were measured over a two-year period to detect whether any significant changes occurred. A computer model was ... continued below

The thermal resistances of the panels were measured over a two-year period to detect whether any significant changes occurred. A computer model was used to analyze the data, adjusting for differences in size of the advanced insulations, and extrapolating to different sizes of composite panels.
