The temperature variations which occur around a structure condition its thermal behaviour and cause variations in its thermal conductivity. As a result of climatic changes, external walls can absorb a certain amount of humidity from the air and produce superficial or internal condensation. The results this has on buildings can be serious: increase in heat conduction by convection or by conduction; rapid degradation of materials; increase in external humidity; accentuation of the negative aspects of the indoor environment, unpleasant external appearance. The report explains the procedure to be followed in verifying whether a specific wall will be subject to condensation, explains the use of the GLASERG computer program, suggests a course of action if condensation is detected, illustrates the thermal and hygrometric characteristics of building materials and gives some examples of the application of the GLASERG program.
