Durable Envelopes for Cold Climates

CCHRC is working with industry partners to identify building envelope designs that can withstand healthy indoor humidity levels. The Mobile Test Lab is a trailer with nine test wall bays, each with a different configuration of studs and insulation—including a control wall with fiberglass batt insulation.

We designed four walls with spray-foam manufacturers Demilec and Icynene to test how low-density spray polyurethane foam performs in the extreme cold climate of Alaska. Two wall cavities are filled with Thermo-Kool cellulose insulation.
