Item

Public building

Energy-efficient renovation

Construction

Location

4500 Solothurn

Information

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. Applying a single 3 cm-thick layer of Fixit 222 Aerogel high-performance insulating plaster to the interior walls has restored vapour diffusion. The system structure absorbs the humidity and releases it back into the room air in controlled doses. This prevents mould from forming.

In order to preserve the original appearance of the exterior façade, Fixit 222 aerogel high-performance insulating plaster was used.
