Beside solid acoustic isolation performed in the study by subcontractor Reference Audio (my task was to make a project of ceiling and to decorate Ecophon with fabric), I used two layers of plasterboard from each side of the wall also in all other rooms. In the outer board there was made a cut up to 15 cm above the floor . level, and it was replaced with fiberglass plaster after flooring was mounted. It is solid enough to function as a baseboard, but it has no profile (no problem of dust), and it is painted as the entire wall. In Russia a classical profiled baseboard is a must, but in given case the customers easily agreed to try living with plain walls. The library by Zonta (Italy) was projected for given interior. . .
