Abstract:
Intro

When an exterior thermal insulation composite system (ETICS) is applied to an outer wall containing trapped moisture, then the insulating material can be subjected to an increased moisture strain during the dryingout phase. Short-term increases in moisture levels may also arise as a result of driving rain. If high temperatures occur at the same time then they may affect the durability of the insulating material. This paper aims to predict the moisture and temperature strans acting on an ETICS with mineral wool insulation under natural climatic conditions and normal usage, using computational simulations. The objective of these calculations is to determine the maximum hygrothermal loads which arise in situ and their duration which can serve as the basis definition of well-founded boundary conditions for durability tests of insulating materials in the laboratory.
