A parametric analysis on the vulnerability of internally insulated solid masonry walls to rot damage

This paper investigates the risk of rot damage in brick solid masonry walls (SMWs) before and after they have received an Internal Wall Insulation (IWI) system. One-dimensional simulations in Delphin were calibrated against laboratory experiments of full-scale insulated and uninsulated SMW assemblies in the Hygrothermal Test Facility. A parametric analysis was conducted to assess the sensitivity of the walls to a list of scenario uncertainties. The results indicated that in all Test Cases (TCs) the risk of rot damage increased when internal insulation is retrofitted to a SMW.
