Abstract

Heat insulation of half-timbered walls in buildings listed as ancient monuments can often only be improved by the application of interior insulation. Interior insulation is however problematic in building terms, and by giving rise to unwanted collection of moisture can endanger the structural integrity of the building. The suitability of a number of different types of interior insulations has been investigated in the twin climate laboratories of the WKI by means of a number of weathering simulations, supported by numerical simulations. Results of the interior insulations applied after that are compared with in-situ measurements taken from refurbished half-timbered buildings. 1 Introduction Whenever historical half-timbered buildings either undergo a change of use or are refurbi
