Q1. Does DCS achieve simultaneous impact and airborne sound compliance?
A1.
Yes, DCS provides:
  • Minimum 150mm concrete mass to prevent noise reaching the opposite side of the party wall.
  • Water pipes supported by complete foam (or similar) resilient material within the service conduit to eliminate vibration of the water pipe due to loose supporting connections.
The use of cross linked polyethylene water pipe combined with the abovementioned characteristics of DCS eliminates any possibility of water hammer from an adjacent sole occupancy. More details provided on request.

Q2. Why is DCS acoustically better than conventional discontinuous party walls consisting of stud walls?
A2.
  • The quality of pipe fixing to avoid water hammering is not reliant on the workmanship of the installer.
  • The system provides better insulation for heat loss in hot water pipes. This ensures significant energy saved for water heating and eliminates water wastage due to availability of hot water in a shorter time.
  • Additional water pipes or power/communication cables can be installed even after the construction of an existing building utilising DCS. The overall wall thickness is significantly reduced.
  • Water hammer is significantly reduced or eliminated on both sides of the party wall.
  • Unlike copper pipes, cross linked polyethylene pipes do not need maintenance since there is no build-up of water impurities in the pipes. This eliminates the need to install water in accessible spaces like stud walls.
  • It is a cheaper and faster way to build in comparison to other alternatives.
