FACT SHEET #13 | QUALICHeCK Study Belgium – Assessment of the Belgian quality control framework for installation of thermal insulation in existing cavity walls

Since 2012, a quality control system is in operation in Belgium to provide confidence in the quality of the works of cavity wall insulation in existing cavity walls. When the works are in line with the quality control framework, the installer may provide a declaration of conformity to the client, which the client can use to receive subsidies or as an input for an Energy Performance Certificate (EPC).

A field study was performed to analyse the relationship between the information provided by installers in the declaration of conformity, the results of the conformity checks performed by the certification organisation and the effective cavity wall performance measured on site.
