How Thick Does Cork Need to Be for Soundproofing? Comprehensive Guide

When it comes to soundproofing, cork has gained popularity as a versatile and eco-friendly material that effectively reduces noise transmission.

But a common question arises: How Thick Does Cork Need to Be for Soundproofing ? In this comprehensive guide, we will delve into the factors that influence cork’s soundproofing capabilities and determine the ideal thickness for various applications.

Understanding Soundproofing with Cork

Cork, a natural material derived from the bark of cork oak trees, possesses unique properties that make it an excellent choice for soundproofing. Its cellular structure allows cork to absorb sound vibrations and minimize their transmission. However, the thickness of the cork plays a vital role in determining its soundproofing effectiveness.

Factors Influencing Cork’s Soundproofing Effectiveness

Material Density

The density of cork directly impacts its ability to block and absorb sound. Thicker cork generally has higher density, which contributes to better soundproofing. However, a balance must be struck, as overly dense cork might become too rigid and lose its sound-absorbing properties.

Airborne vs. Impact Noise

The type of noise you’re dealing with affects the optimal cork thickness. Thicker cork is more effective against impact noise, such as footsteps or dropped objects, while airborne noise may require a combination of cork and other soundproofing materials.

Application Area

Different spaces require different cork thicknesses. A home theater might need thicker cork than a bedroom due to the intensity of sound produced. Assess the noise level and purpose of the room to determine the suitable thickness.

How Thick Does Cork Need To Be For Soundproofing (Explanation)

Residential Spaces

For residential spaces like bedrooms and living rooms, a cork thickness of 6-8mm is often sufficient. This thickness offers effective noise reduction without adding excessive bulk to the walls or floors.

Commercial Establishments

In commercial settings such as offices and restaurants, where higher foot traffic and ambient noise are common, a cork thickness of 10-12mm may be more appropriate. This additional thickness helps maintain a quieter and more comfortable environment.

Home Studios

Home recording studios require meticulous sound control. A cork thickness of 12-15mm or more is recommended, especially when considering both airborne and impact noise. This ensures the quality of audio recordings and minimizes sound leakage.

Installation Techniques for Cork Soundproofing

Proper installation is crucial for achieving optimal soundproofing results with cork. The installation method varies based on the application area:

Wall Application

When soundproofing walls, cork panels can be adhered using a strong adhesive. Make sure to cover the entire surface area, paying extra attention to corners and seams.

Floor Application

For floors, cork underlayment can be installed beneath the flooring material. Ensure a uniform and secure installation to prevent gaps that might compromise soundproofing.

Ceiling Application

Cork can also be applied to ceilings to reduce sound transmission between floors. Use appropriate hardware and ensure the cork is securely attached to prevent it from sagging over time.

Advantages of Using Cork for Soundproofing

  • Natural and Sustainable: Cork is an environmentally friendly material, making it a responsible choice for soundproofing.
  • Thermal Insulation: Cork offers additional insulation benefits, helping regulate indoor temperatures.
  • Easy Installation: Cork panels and underlayment are user-friendly and can often be installed without professional help.
  • Versatile Aesthetic: Cork can be finished to complement various interior designs.

Disadvantages to Consider

  • Cost: High-quality cork can be relatively expensive compared to other soundproofing materials.
  • Maintenance: Cork requires proper care to maintain its soundproofing and aesthetic properties.

Maintaining and Caring for Cork Soundproofing

Regular cleaning with a damp cloth and mild detergent is sufficient to keep cork soundproofing in good condition.

Avoid abrasive cleaners or excessive moisture, as they can damage the cork’s structure.

Can you use a corkboard for soundproofing?

Yes, a corkboard can be used for soundproofing to some extent. While cork is not as effective as specialized soundproofing materials, it does possess sound-absorbing qualities that can help reduce noise transmission in certain situations.

A corkboard is made from compressed cork granules, and its porous structure allows it to absorb sound waves to some degree.

When installed on walls or ceilings, corkboards can help mitigate echo and reduce reverberation, improving the overall acoustics of a room.

They work well in spaces like home offices, bedrooms, or study areas, where the goal is to create a quieter and more focused environment.

However, it’s important to note that corkboards might not provide the same level of soundproofing as other materials designed specifically for that purpose, like acoustic panels or foam.

They are more suited for addressing minor noise issues and improving the ambiance of a room rather than completely blocking out external noises.

For more effective soundproofing, especially in areas with high noise levels or specific acoustic requirements, considering a combination of corkboards with other soundproofing solutions might yield better results.

Comparing Cork with Other Soundproofing Materials

While cork is effective, it’s worth considering alternatives like acoustic foam or fiberglass panels, especially for specific noise challenges.

DIY vs. Professional Installation

DIY installation can be cost-effective, but for complex applications or optimal results, professional installation might be worth the investment.

Budget Considerations

Factor in the cost of cork material, additional soundproofing elements, and installation when budgeting for your project.

Environmental Impact of Cork

Cork is renewable, biodegradable, and harvested without harming trees, making it one of the most eco-friendly soundproofing materials available.


In conclusion, the thickness of cork for soundproofing varies based on factors such as noise type, application area, and budget considerations. By understanding these variables and choosing an appropriate thickness, you can enjoy a quieter and more peaceful environment while contributing to sustainability.
