How to Soundproof a Pipe

soundproof a room header

Pipe Soundproofing

Pipes, a necessary part of a house, are kept hidden behind walls and ceilings, away from the living space. But these walls and ceilings provide little soundproofing. 

Pipe soundproofing can be achieved in two ways: wrapping the pipes with noise blocking materials and filling the cavities around the pipes with sound absorption products. Using both noise blocking and sound absorption materials can eliminate the sounds of pipes in your home.

While pipe soundproofing is recommended during construction, any exposed or accessible existing pipe can be treated. Post-construction treatment is especially common in older homes that still use cast iron pipes. Copper and PVC piping, which also create unwanted noise, can be also treated after construction.

Recommended Methods

Wrapping pipes with a dense vinyl material will block the noise and dampen the vibrations.

We recommend Quiet Wrap™ Pipe Soundproofing Wrap, which will significantly reduce noise created by pipes. This is an industrial grade barrier/foam composite manufactured with a high density sound barrier membrane and laminated with an acoustic grade polyurethane foam. With its peel-and-stick backing, installation is quick and easy.

One of the reasons why Quiet Wrap™ Pipe Soundproofing Wrap is so effective at pipe soundproofing is because of the way water pipes tend to create sound. Much of the noise that noisy water pipes generate comes from the impact-related, vibrational noise of water beating against the walls of the pipe as it rushes through.

This is why the polyurethane foam layer is so critical to Quiet Wrap™ Pipe Soundproofing Wrap’s effective soundproofing. While the barrier blocks most standard noise, the layer of polyurethane foam both isolates the barrier, making it a more effective sound blocker, and reduces the vibration of the pipe, deadening the impact noise.

The result is a much quieter or even unnoticeable pipe sound. Quiet Wrap™ Pipe Soundproofing Wrap is suitable for any size waste water pipes, PVC pipes or cast iron, so you can order with confidence to quiet your plumbing noise.

When deciding how to soundproof a pipe, you may be limited by the construction of the building where the pipe is located. Sometimes it’s not feasible to try to access the pipe directly to try to wrap it in soundproofing wrap.

If the pipe is encased in drywall, use a sound absorption product like Quiet Batt® Soundproofing Insulation. This dense, recycled, cotton material can be installed around the pipe in the empty space of the drywall, eliminating the sound vibrations made by the piping. Quiet Batt® Soundproofing Insulation, not only reduces sound, it also insulates.

In the past, people may have been reluctant to attempt to dull sound from pipes by filling the cavities in the wall because the insulation available often did not fit the space well and had an undesirable chemical composition. Since Quiet Batt® Soundproofing Insulation is mostly recycled cotton material, you can handle it without gloves and easily place it where it needs to go without concerns that you should be utilizing a more natural material.

It is also designed to fit tightly in the cavities for maximum dampening of sound from the pipes. Quiet Batt® Soundproofing Insulation also has a Class A flammability rating so you can install it in your walls with peace of mind.
