Stop the Noise through Acoustic Isolation with HoldRite Silencer System Products


Vibrations cause shaking and shaking produces noise. When machinery, piping, or ductwork vibrate, the resulting sound can travel throughout the structure, causing noise and unwanted sound. Such vibrational noise serves as a common irritant to building occupants and is a primary reason for tenant complaints.

While there are several ways people have discovered to “soundproof” a house, as this piece in the Chicago Tribune attests, soundproofing plumbing systems pose different challenges. Plumbing system noise is generally considered one of the most intrusive and difficult sounds to mitigate. Once such an issue arises, it can quickly become a complicated, labor-intensive, and expensive problem to solve.

While it once took extensive time and energy to locate the proper materials and perform a quality installation, recent advances in materials and methods have made the mitigation of plumbing system noise one of the easiest and most affordable tasks in sound-proofing a building.

Enter Acoustic Isolation

Acoustic isolation is the key to preventing noise problems stemming from vibrations, effectively dampening the noise transfer between piping and building structures. Such noise may originate from a variety of sources, including:

  • Drainage systems such as sanitary waste piping, storm drainage piping, and bathtubs.
  • Water supply and distribution systems such as pressurized potable and non-potable water systems
  • Fixtures, faucets, and appliances manufactured from a material such as stainless steel, cast iron, fiberglass, and plastic.
  • Valves, pumps, and equipment, which emit noise levels depending on the friction or turbulence they generate.

The HoldRite Silencer System

To provide effective acoustic isolation, HoldRite has put together an excellent package of products called the HoldRite Silencer System. This product system is complete with variable-length acoustic isolation solutions such as:

  • Clamps & Inserts: Ideal for sound-rated and isolation application these products are specifically engineered to dampen noise transfer.
  • Isolation Liners: Composed of either rubber or felt for sound and vibration isolation.
  • Riser Pads: Minimize noise and vibration transfer at piping stacks and risers.
  • Hangers: Ideal for noise & vibration isolation and dissimilar metal isolation.
  • Galvanized Brackets: Ideal for vertical or horizontal use in rooms like lavatories, showers, and water closets.
