Summary

DESCRIBES HOT PLATE MEASUREMENTS OF HEAT CONDUCTION AND WATER VAPOUR DIFFUSION ACROSS THERMAL INSULATION MATERIALS. HEAT TRANSFER INCREASES WITH MOVEMENT OF MOISTURE DURING TEMPERATURE DROPS. CALCULATES THE INCREASE IN THERMAL CONDUCTIVITY FROM THE DIFFUSION FLOW PER UNIT OF AREA TO DERIVE VALUES GENERALLY INFERIOR TO MEASURED QUANTITIES. THE INCREASE IN HEAT TRANSFER DUE TO WATER VAPOUR DIFFUSION MEASURED UPON FULL-SCALE WALL SPECIMENS WAS LESS THAN THAT DETERMINED BY THE HOT PLATE MEASUREMENT. CONCLUDES THAT THE HEAT TRANSFER CAUSED BY MOVEMENT OF MOISTURE IS NOT A CHARACTERISTIC OF THE MATERIAL, BUT A PROPERTY OFTHE ENTIRE WALL STRUCTURE. (INT. BUILD. SERV.
