Understanding the performance of solid walls

An article by Caroline Rye and Cameron Scott for IHBC’s magazine, Context which discusses their research into the energy performance (heat loss, moisture content) of traditional construction in historic buildings. Their findings showed that walls insulated with vapour-open, woodfibre insulation had much more satisfactory levels of relative humidity (below 80% RH, on average) than those insulated with commonly used materials such as PIR (90% RH, on average, and rising year on year). Relatively humidity levels of over 80% is deemed the point where mould growth can flourish.
