Hygrothermal performance of bio-based insulation material in wood-frame walls exposed to unintended moisture sources
The attention for energy performant buildings with a low environmental impact has been growing over the years and as a result, the use of bio-based insulation materials as well as wood frame constructions has becomemore and more prevalent in Belgium and Europe. This research assesses the hygrothermal behavior of bio-based insulation materials, used in wood frame walls.The study concentrateson theirdurability and thermal performance, when exposed to unintended moisture sources. Two different leakagesare looked at: one originatingfrom imperfections in the weathering sealantat the exterior, and asecond is introduced due toinsufficient air tightnessat the interior, causing infiltration of humid indoor air into the wall system and the occurrence of interstitial condensation. Primarily results show the dominant impact of the ventilation rate in the cavitybetween the masonry outer leaf and the wood frame wall, on the durabilityand thethermal performance of the structure.Also, there is higher negative impact by exterior leakages on highly absorptive bio-based insulation materialcompared to the traditional mineral wool setup.
