In recent years concerns have been raised by the stakeholders of Canadian Roofing Industry about the true fieldx000D
performance (thermal resistance) of closed-cell foam insulation in Canadian climates with extreme temperaturex000D
conditions and variations. Studies have already indicated that thermal resistance of closed-cell foam insulationx000D
with captive blowing agent/s is a non-linear function of temperature, unlike other traditional thermalx000D
insulations such as glass fiber, mineral wool etc. This unusual thermal characteristic of closed-cell foamx000D
insulation results in over estimation of energy performance of building envelopes. In this scenario, roofingx000D
industry is looking forward to receive credible technical guidance, based on comprehensive research outputs,x000D
for realistic thermal resistance value of closed-cell foam insulation board that reflects the field boundaryx000D
temperature conditions and type of constructions. The proposed research project aims to address this issuex000D
through further laboratory, analytical and numerical studies and reaffirm the credibility of current roofingx000D
design and construction practices in Canada.
