How do you soundproof your home? What kind of insulation should you use? This guide will help you find the right type of insulation to soundproof your walls, floor, and ceiling.

Soundproofing your home can help eliminate irritating sounds from outside and inside your house, which could potentially improve your quality of life as well as that of your neighbors.

Read on to learn everything you need to know about soundproofing insulation.

How does soundproofing insulation work?

Soundproofing insulation works in one of two ways. The first is by providing a barrier between the sound source (e.g., a wall with a noisy neighbor) and the receiver (e.g., your living room).

The second is by acting as an absorber of sound waves that are created by loud noises near it. This can be accomplished by filling the material with dense materials such as cotton or wool, which absorb sound waves better than other materials like fiberglass or rock wool.

Depending on what kind of soundproofing insulation you’re using, either of these methods may work best for you.

Popular Types of Soundproof Insulation

There are many ways you can soundproof your home, but insulation is one of the most popular. Soundproof insulation comes in a variety of types, so it’s important to know what type you’re interested in before making a purchase.

For example, fiberglass insulation is inexpensive and easy to install; however, if you have pets that shed or children who may be allergic to fiberglass, then polyurethane foam would likely be a better option.

Foam Boards and Tiles

Foam boards are popular soundproofing insulation materials. They are often used in the construction of walls and ceilings. They can also be glued to existing walls or ceilings as a sound-dampening solution.

Foam boards come in a variety of thicknesses, with the thicker ones providing more sound-dampening capability. They can be purchased in large sheets or cut into smaller pieces for easier installation on areas like doorways or windows.

Soundproof tiles are a cheaper alternative that provide similar noise reduction benefits as foam boards.


Rockwool is a popular choice because it’s easy to install and provides excellent sound absorption. Rockwool also comes in sheets that can be cut into any size of room you need, no matter how big or small.

Mineral Wool

If you want a quick fix for the sound coming from your speakers or TV downstairs, then mineral wool insulation is another good option.

It’s inexpensive and easy to install on a perforated metal panel. It does not provide soundproofing that’s as effective as other types of insulation, but it will help with any noise coming from the lower levels of your home.

Fiberglass Batts

Fiberglass insulation is one of the most popular types of insulation in use today. It’s easy to install and relatively inexpensive compared to other soundproofing insulation options.

The main disadvantage of fiberglass insulation is that it has a shorter lifespan than other types of soundproofing insulation.

These batts are also easy to install and can be installed by most people without any prior knowledge of carpentry or construction skills. These batts are not as effective as honeycomb panels when dealing with high frequencies like sirens, human speech, etc., but they’re still useful for basic noise reduction.

Honeycomb Panels

The installation process for honeycomb panels is pretty simple but time-consuming. You must cut a hole in your wall big enough for the honeycomb panel and then secure it with nails or glue. It will cover about 90% of the sound coming from inside the room that you’re trying to deaden.

How much does soundproof insulation installation cost?

The average cost is about $20 per square foot. Soundproof insulation installation costs vary depending on the size of the room as well as your insulation contractor. Another factor is the type of insulation you choose. You can buy soundproofing insulation in bulk or by the sheet, which will be cheaper than buying it as carpet padding or other types of insulation.
