Conversion / Restoration


8153 Rümlang


A multiple-family dwelling located in the centre of Rümland. Part of the façade was insulated with Flumroc Compact Pro mineral-wool panels, the rest (for reasons of space) with Fixit 222 Aerogel High Performance Insulating Plaster. The old base and finish layers were removed in advance of the application of the Aerogel insulating plaster. This allowed the original window and door frames to be used as before.

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
