AbstractAs part of its continuing program of research on performance of the building envelope and in cooperation with the SPI/NRC Fellowship Program, the Institute for Research in Construction recently undertook projects to evaluate the thermal performance and air leakage performance of wood frame residential walls. Evaluation of thermal performance included measurement of the thermal resistance of 2.4 x 2.4 m test specimens at three mean temperatures. Thermal resistance of the specimens was measured using the Institute' s guarded hot box apparatus. Four specimens with sprayed-in- place polyurethane insulation were included in the project. Evaluation of air leakage performance included measurement of the air leakage rate through 2.4 x 2.4 m test specimens at pressure differences corresponding to those normally exerted on the building envelope, and assessment of the structural performance of the air barrier system at pressure differences corresponding to gust wind loading. Air leakage performance was evaluated using the Institute's air leakage apparatus. One specimen with sprayed-in-place polyurethane insulation was included in the air leakage project. This paper describes the test procedures used in the test series and reports on the initial results of the test program.
