Conversion of a correctional facility into hotel/restaurant premises. The main planning effort was focused on the protected façade of the building, from which modern constructional elements (bay windows) extended. Using our Aerogel High Performance Thermally Insulating Plaster, the 350 m² west façade was insulated in accordance with the requirements of the preservation authorities.

Das spätgotische Gebäude diente vermutlich der 1460 gegründeten Bullingerpfründe als Kaplanei und wurde nach der Rekatholisierung 1531 zur Helferei. Die rund 500 Jahre alte Liegenschaft, welche mittlerweile unter Denkmalschutz steht, wurde im Laufe der Nutzungszeit immer wieder renoviert, letztmals vor 60 Jahren vollumfänglich und 1990 mit einer sanften Innen- und Aussenrenovation.

Energy efficient renovation Chesa Palmira, Bever

The Chesa Palmira was built in 1672, and the original floor plan has remained unchanged till today. The façade of this historic building was energy efficiently renovated by applying an 8 cm thick layer of Fixit 222 Aerogel High Performance Insulating Plaster. Fixit 208 was used for the final coat. Finally lime whitewash was applied to the façade and the identical sgraffito pattern from 1952 was carved into it.

Façade renovation, Barandun, Zillis

Façade renovation with Fixit 222 Aerogel High Performance Insulating Plaster. Existing base layer removed, masonry dry cleaned and the entire façade fixed with a tile rabitz. 3 – 5 cm of Fixit 222 was applied directly onto the tile rabitz. Then Fixit 733/734 Stucco final coat was applied and two layers of Fixit 784 paint rolled on.
