case study
Ceiling soundproofing renovation in Montreal
Cost: $26,715
Duration: 6 weeks
The project involved opening the ceiling on the first floor of a 1930s Montreal duplex and replacing the plaster finish with a gypsum ceiling system. Aluminum electrical wiring was also replaced to conform to current standards, and the existing lighting was exchanged for new pot lights in all rooms.

Once the ceilings were opened, an acoustic, soundproofing insulation system was installed to absorb interior noise from the second floor of the duplex. The soundproofing system consists of blown wool insulation, padded with a thin layer of air between it and the gypsum ceiling finish, along with the installation of resilient bars.
This project was completed in collaboration with Rénovation Générales E.C.S.
