Both conductive heat transfer and air leakage through the building enclosure have been identified as obstacles to truly energy efficient buildings. This article delves into the necessity for proper detailing of both continuous insulation and fluid-applied air barriers, pointing out the difficulties in avoiding pitfalls such as thermal bridging in wall assemblies. It also explores why more insulation is not necessarily a means to increase energy efficiency.
