Following the publication of an earlier literature review, this project aims to help fill the gaps in current knowledge by offering insight into traditionally constructed buildings which have been retrofitted with AVCLs (Air and Vapour Control Layers). The project will review a selection of case studies and report on the findings, including any positive or negative consequences, of the installations.
