An interactive online CPD on internal wall insulation (IWI) – by our Patron Member, Ecological Building Systems. This CPD will cover the impact of moisture on solid stone/brick walls, the causes of moisture ingress and how walls function before and after applying insulation, the necessity of moisture management in solid masonry walls and the importance of using diffusion open materials. Case studies will demonstrate best practice examples of various solid masonry wall insulation systems using breathable materials to ensure building structural safety and longevity.
