Under the expert guidance of their drywall contractor, SPAAR, the assembly was engineered to better attenuate noise between adjoining units. The construction process utilizes a multi-phase approach designed to maximize both mass and physical separation. First, the team installs 9 inches of total insulation using a combination of Johns Manville and Owens Corning sound and thermal batt insulation. The structural joists are then completely covered with SONOpan panels to stop airborne noise from passing through the assembly. Finally, resilient channels are added to the system before installing two heavy sheets of 5/8″ Type X Drywall. These channels decouple the drywall from the framing, effectively stopping vibration noises and structure born sound.
