Atlanta High Rise Installs SPC Flooring Solutions

Following a recent mandate by the condominium association to reduce neighbor noise, SPC was approached to design flooring solutions for remodels throughout an Atlanta high rise building.

Residents complained of high levels of sound and impact noise being transmitted from the floors above. They needed a strategy for upgrading the sound isolation characteristics of the existing 6” concrete sub-floor.

The SPC solution in this case was to make use of a semi-decoupled floor using OSB/Plywood layered with Serena Underlay and Green Glue dampening compound. This type of build has resulted in a significant reduction in both impact noise and overall sound transmission.

  • PROJECT: 6” concrete floor upgrade
  • OBJECTIVE: Reduce impact noise transfer in floor remodel
  • STRATEGY: Add a semi-decoupled floor using Green Glue dampening compound, OSB/Plywood and 3/8″ Serena Underlay.
  • Results:
    + Increase of 28 IIC
    + Increase of 36 STC
