Field measurements and simulation of an massive wood panel envelope with ETICS

Abstract

ABSTRACT Sufficient dry-out capacity of the constructional moisture is important for solid wood structure wall assemblies, especially with a non-ventilated façade system. The objective of this study was to create a validated simulation model of a Massiv-Holz-Mauer (MHM) panel external wall with ETICS (External Thermal Insulation Composite Systems) based on the field measurements. Field measurements were carried out in a two-floor wooden detached house. Temperature (t) and relative humidity (RH) were measured between the material layers of the external wall. Results of field measurements were used to create and validate a one-dimensional simulation model. It was concluded that the validation of the created simulation model was successful, and simulations were very similar to the field measurements. The simulation model can be used for future studies to evaluate the hygrothermal performance of the MHM panel envelope with ETICS.
