Summary

DESCRIBES THE RESULTS OF THERMAL RESISTANCE MEASUREMENTS ON 11-YEAR OLD WALL PANELS INSULATED WITH FOAMED POLYURETHANE. FINDS THE PANELS HAVE THE SAME THERMAL RESISTANCE AS ON THE DAY OF MANUFACTURE. HOWEVER IT CANNOT BE ASSUMED THAT THE FACING LAYERS PREVENTED INGRESS OF AIR INTO THE POLYURETHANE CORE, SINCE ANALYSIS OF THE CORE IN ONE OF THE PANELS SHOWED THAT ITS THERMAL CONDUCTIVITY WAS DIFFERENT FROM WHEN IT WAS MADE. ALSO SETS OUT THE RESULTS OF MEASUREMENTS ON POLYURETHANE PANELS FACED WITH ALUMINIUM FOIL WHICH DOES NOT PREVENT AGING OF THE PANEL. FINDS THAT ASURFACE COATING CAN AFFECT THE INGRESS OF AIR AND THUS THE CHANGE IN THERMAL CONDUCTIVITY OVER TIME. (INT. BUILD. SERV. ABSTR., GB., 25, N 2, 1990/03-04, 90-00619.
