Purpose:

This project tested wall assemblies most commonly used in B.C. to see how they meet the B.C. energy requirements and whether they can remain durable in a coastal climate. Six types of wood-frame walls with different thermal insulation strategies, all meeting the R22 effective (RSI 3.85) requirement were included. Hygrothermal performance measurements gathered over a 19 month period provided valuable data for designing durable and energy efficient wall assemblies
