Abstract
Hydrophobization reduces the water absorption by facade materials and is often suggested as an optional measure to reduce the risk of moisture problems in in-ternally insulated facades. Studies regarding hydrophobization have mainly fo-cused on moisture performance and whether the treatment is safe to apply to his-toric building facades.
Little focus has been on how the treatment affects heat loss due to the walls becoming drier. This study investigated the effect of hydrophobi-zation on heat loss for solid masonry walls. The study comprises: field measure-ments from a large-scale experimental set-up containing solid masonry test walls with and without internal insulation and hydrophobization, and a simulation study.
Both studies showed a generally positive effect of the hydrophobic treat-ment on heat loss, although simulations show a low dependency on the type of insulation system compared with field measurements.
