The walls of the buildings in general and the external walls in particular perform a major role in building, both in financial impact and in the role they play in habitability. External walls must provide acoustical and hydrothermal comfort, protection and security against intrusion, water tightness, must be long-lasting and meet the requirements associated to their use and performance. Masonry has been the elected material for the execution of external walls as it has paid an important role in buildings since first civilizations. However, since the beginning of the 20th century, masonry became confined to simple stuffing roles, as concrete and steel started to perform structural functions. Nowadays, most external walls are built with double wall layers with an inner thermal insulation and ventilation space. Certainly, the complexity that involves a building of this kind of walls increases the possibility of several anomalies. As a matter of fact, the normal evolution of the buildings outside should involve the use of simple layers. It means a lower complexity in execution and less time waste which leads to economical savings as far as workmanship is concerned. As far as the building materials are concerned one should consider the greatest possible number of criteria available and avoid cheap solutions, a trend which corresponds to the most affordable price per unit.
