Hygrothermal study of curative solution
Pathology of humidity. Clad walls - Case study

The cause of the prevailing pathology is undoubtedly the air gap created by the glue beads and, consequently, the maintenance of plaster "1" in a "cold wall" situation, which rapidly reaches its critical humidity level.

The aim of the curative solution is to thermally transform this area into a "warm wall". There are three ways to achieve this.

• Solution 1. constantly lower and maintain the indoor relative humidity HR_i < 30%, when T_i = 19 °C and T_e = - 5 °C.

  And also, be able to vary HR_i according to variations in T_e. Worth knowing:

  • when T_e = 0 °C have HR_i < 41% ;

  • when T_e = 5 °C have HR_i < 54%.

  This is "mission impossible".

• Solution 2. Raise the...
