Abstract

The main goal of this paper is to establish a method to analyse the progressive failure of external thermal insulation composite systems (ETICS) over time, with the aim of devising a mathematical formula that contemplates the mechanisms of degradation, the type of cladding and the characteristics of the system itself. Apart from the theoretical work, the method is based on field work, which consists of the visual inspection of a sample of buildings under normal exposure conditions. The data obtained in the field survey are processed and converted into numeric indicators to allow identification of the degradation patterns and estimation of a reference service life for ETICS.
