Conversion / Restoration


CH - 4125 Riehen


Energy-efficient renovation of 48 apartments in 8 residential buildings. Some 2'800 m² of Fixit 222 Aerogel High Performance Thermally Insulating Plaster and 600 m² AeroCalce non-woven fabric matting were applied, the former directly onto the existing plaster substrate. This technique was economic despite the higher material outlay because it allowed the entire renovation to be completed in one step rather than two, as initially envisaged. On completion the façades appear practically unchanged, whilst the energy consumption has been halved.

The Fixit renovation technique, including the use of a 30mm thick plaster layer of Fixit 222 Insulating Plaster, created a novel room climate based on its water-vapour permeability. The combined layers of the plaster system absorb excess humidity from the air and return it in a controlled way to the room, preventing the development of mildew
