Soundproofing with Cork and Drywall

People often glue cork to the walls of a room to act as soundproofing. Cork provides a layer of material that can diffuse sound to a certain extent. It acts as an insulating material for the room.

Why Use Drywall

Cork alone does not offer a great deal of soundproofing for a room; however, if you put cork over drywall and then put another layer of drywall over the cork, you will create a strong soundproofing system. The soft cork will create a layer of air between the two layers of drywall.

The cork, along with the air trapped within it, helps to soundproof.


Cork can be used in a lot of ways to soundproof your home. It can be used as an underlayment under flooring, as flooring altogether, and as wall or ceiling tiles. Here, we're going to discuss how to use cork tiles. If you use these tiles, you won't always need to put drywall over it.

Doing so, though, creates more finishing options and even better soundproofing qualities.

Step 1 - Purchase Materials

Before you begin the process of installing the cork tiles, you will need to order them. Start by measuring the room so you know how much to order.

You can go to a home improvement store with your measurements in tow. Someone there will be able to help you order the materials and give you some installation tips.

Once the cork tiles come in, leave them in the room in which you plan to install them open for at least two days so they can adjust to the climate where they are being installed. The tiles can expand and contract so this will ensure that they are at their final size before you lay them.

Step 2 - Lay Tiles

Lay the tiles in the pattern you want before installing them. You could consider staggering them or lining everything up perfectly. If you get different shades of the cork or painted cork tiles, you could do a more complicated pattern.

Step 3 - Install the Tiles

Once you know the pattern you are planning to use for the tiles, it's time to install them. Use a strong adhesive. Someone at the home improvement store where you order the tiles will be able to recommend one that will work well with the specific tiles you order.

Let the tiles set overnight or for at least 10 hours before you do anything else.

Step 4 - Finish and Paint

Not all cork tiles come finished. If yours didn't, now's the time to add a finish and even paint if you really want to change the look.

Make sure the tiles are clean before you paint or stain them. Also, be sure to have windows open in the area and fans going. This will prevent the fumes from harming you and also help the tiles dry faster.

Step 5 - Maintain the Tiles

To ensure your cork tiles have a long life, be sure to keep them in good shape. To do so, clean them the same way you would other wood products. Do not use harsh chemicals.

Other Steps

If you are adding drywall over the tiles, do so before Step 4. Install the drywall as you normally would. This will add yet another sound barrier and drywall offers you many options when it comes to the look and feel of the home.
