The historic 12th-century prison was converted into a restaurant and hotel over a period of two years. The main focus during the planning phase was on the listed façade. The exterior façade was supplemented with modern, cubic elements (bay windows) – these form a second visual level. The façade was energetically renovated in accordance with strict heritage conservation guidelines using Fixit 222 aerogel high-performance insulating plaster.

Parish assistant's house renovation Bremgarten

Parish assistant's house renovation Bremgarten

The late Gothic building probably served as a chaplaincy for the Bullingerpfründe and became a parish assistant's house after the recatholisation in 1531. The building, which is now a listed building, has been renovated several times over the centuries – most recently in 1990. Following the conversion and energy-efficient renovation in 2016, the historic building continues to be used for residential purposes. A studio was created on the ground floor, which could also be used as a one-room flat with a small kitchen and bathroom. A 2.5-room flat was created on the first floor and a 4.5-room maisonette flat on the second floor. In addition, a basement extension with a new archive for the parish was built.

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.

Residential home ‘Wyssestei’ internal insulation Solothurn

At the Wyssenstei residential home, residents spend most of their day in their living quarters, which means that the humidity in these rooms is generally high. The rooms were originally fitted with a vapour-proof system, which led to mould forming behind chests of drawers, shelves and cupboards. The application of Fixit 222 aerogel high-performance insulating plaster in a layer thickness of 3 cm created a vapour-permeable indoor climate. The system structure absorbs the humidity and releases it back into the room air in controlled doses. This prevents mould from forming.

Apartment building ‘Hotel Meyerhof’ renovation Hospental

The former Hotel Meyerhof was converted into an apartment building in 2021 after standing empty for over 30 years. The energy-efficient renovation was carried out using Fixit 222 Aerogel high-performance insulating plaster with a layer thickness of 6–8 cm. To do this, the existing plaster was removed down to the quarry stone masonry and the insulating plaster was sprayed on by machine. The large, white façade surfaces were coated twice with Fixit 777 fine plaster with a grain size of 0.5 mm. The small grey areas were created using a mixture of Fixit 205 base plaster and Fixit 208 base mixture (homemade Worms plaster). Finally, the exterior façade was painted twice with mineral paint.
