A product to compliment EWI and combat condensation risk
Mould growth and surface condensation are problems for many dwellings, and the retroﬁtting of insulation can increase the risk of these occurring. This is especially the case for historical solid wall properties receiving external wall insulation (EWI), which often have architectural details at the roof eaves that cause discontinuities in the insulation and so can result in excessive thermal bridging. This paper presents the results of an investigation into retroﬁtted solid wall properties where modelling is used to investigate the problem and eﬀectiveness of insulated coving products which are designed to reducing thermal bridging. Thermal modelling is undertaken to establish the optimum design to reduce risk. The insulated coving was found to be eﬀective in reducing thermal bridging in all the scenarios investigated and to reduce moisture risks occurring in some solid walls situations.
