The Importance of Moisture Transport Properties of Wall Finishings on the Hygrothermal Performance of Masonry Walls for Current and Future Climates

A render is the first protective layer of exterior walls against outdoor climate, which, due to its constitution, aims gradually slow down liquid moisture penetration prevent it from reaching wall inner layers. Due future expected changes in today’s mortar might not be adequately designed protect these walls. This paper analyse influence mortars on hygrothermal performance solid brick under current and climates. The study includes four types assemblies three mortars, was carried out for Lisbon other climates by using a computational simulation tool. Finally, gains respective reach wind-driven rain (WDR) spells were assessed means weather files Lisbon’s climate. It shown that influenced differently depending characteristics layers conditions. In terms WDR spells, aside precipitation spell period, distribution events within also conditions dryness assembly. depth able varies between 94 200 mm.
