Interior insulation of masonry walls – An assessment method (original) (raw)

2013

Abstract

ABSTRACT Regarding the retrofit of existing buildings, exterior thermal insulation systems are generally considered as a good solution and their advantages result in an optimal hygrothermal performance of the building facade. However, with respect to the renovation of a building facade, interior insulation is often the only possible retrofitting solution, due to architectural, esthetical or economical reasons. In current building practice, the use of hygrothermal simulation for the design of an interior insulation system is often considered as relatively complex and intensive. Alternatively, guidelines and recommendations to assist building engi-neers and designers with the application of interior insulation have been developed in Germany (WTA), and in Denmark (Videncenter for energibesparelser i bygninger). In this paper, an assessment and design method for the interior insulation of masonry walls, recently published in Belgium, is presented. The method focuses on the analysis and diagnosis of the existing building facade. The stepwise approach intends to help the building engineer and architect with the design of the interior insulation.
