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
