Avoidance and diagnosis of problems associated with internal wall insulation

Abstract

Improving energy efficiency and comfort of traditional buildings affects how moisture moves through the building fabric. Internally insulating solid masonry walls can have a hugely positive impact on comfort, but doing so without regard for this relationship can lead to undesirable consequences, including trapped moisture and mould growth. A well-designed specification informed by a good understanding of the building and its context will preclude any unintended consequences.
