Detached house ‘Chesa Sonder’ renovation Zuoz
This historic building, dating from 1651 and classified as worthy of preservation, shows the centuries on its exterior façade. For the energy-efficient renovation, Fixit 222 Aerogel high-performance insulating plaster was applied to the façade in a layer thickness of 7–8 cm using a spraying method. Fixit 203 finishing plaster with hydraulic lime was applied as the finishing coat and then painted twice with Fixit 784 OF mineral sol-silicate paint. The exterior wall adjacent to the stable next to the building was insulated with 140 mm thick COMPACT PRO rock wool insulation boards.
