Sanitary Flow Noise Solution
Water flowing through PVC soil and waste pipes often causes noise issues in various buildings. In apartments, hotels, and office buildings, this noise can be particularly disruptive to occupants. To reduce this annoyance and comply with sound insulation standards in residential areas, it is essential to insulate the pipes using Acoustic Pipe Lagging. This revision maintains the original meaning while enhancing clarity and flow.
Our Expertise
The sound insulation for soil, waste, sanitary drainage, and water pipes shall be Armawave 2540 acoustic lagging or an equivalent product. This insulation should be manufactured with acoustic isolation foam and a mass barrier, with a total weight of at least 5kg/m2. The acoustic insulation must be certified by an independent, NATA-accredited laboratory and demonstrate equivalent sound insulation performance.
For pipes located in wall or floor cavities that serve or pass through multiple sole-occupancy units, the sound insulation requirements are as follows:
- If the adjacent room is a kitchen or non-habitable room, the insulation should achieve an RW + Ctr (airborne) of at least 25.
- If the adjacent room is habitable, the insulation shall achieve an RW + Ctr (airborne) of at least 40.
Installation of the acoustic insulation must adhere to the manufacturer’s specifications. It should be cut to size to fit all pipework neatly, incorporating overlaps on all joins. All joins must be secured using appropriate foil tape or adhesive.
