Description

The following paper studies the year-long moisture conditions associated with vacuum insulation as the exterior insulation. The exterior insulation of one assembly was renovated by using 50.8 mm (2 inch) of expanded polystyrene (EPS) and represents the baseline performance of current common practice. Another assembly was built with 20 mm (0.7 inch) vacuum insulation panels encased in the equivalent thickness of EPS to represent a high RSI-value retrofit. The thermal performance was evaluated using a guarded hot box facility at Carleton University and the in-situ Building Envelope Test Hut at CanmetENERGY-Ottawa. The temperature, humidity and moisture content in the sheathing measurements from February 2017 to March 2018 are presented. Experimental results were compared to failure criteria outlined by ASHRAE Standard 160 to determine if the proposed building envelope system would be suitable in a cold, humid climate.
