The Ultimate Guide to Soundproofing Your Floors


As an expert in the field of soundproofing, I have seen firsthand the importance of having a quiet and peaceful environment. Whether you live in a busy city or have noisy neighbors, unwanted noise can be a major source of stress and disruption in our daily lives. That's why it's crucial to invest in soundproofing products, especially for your floors. In this comprehensive guide, I will walk you through everything you need to know about soundproofing your floors, from the different types of acoustic bases and underlays to the best soundproofing products on the market.

The Basics of Soundproofing

Before we dive into the specifics of soundproofing your floors, it's important to understand the basics of soundproofing.

Sound travels in waves and can easily pass through materials such as wood, concrete, and even air. This is why it's essential to use materials that can absorb or block sound waves to effectively reduce noise transmission.

Acoustic Bases and Underlays

The first step in soundproofing your floors is to choose the right acoustic base or underlay. These are materials that are placed between your flooring and the subfloor to provide a layer of insulation and cushioning. There are several types of acoustic bases and  soundproof underlay available on the market, including vinyl flooring, dura-son, geniemat rst, impactomat 5, and mutemat range.

Vinyl Flooring:

Vinyl flooring is a popular choice for its durability and affordability.

It also has good sound absorption properties, making it an excellent option for soundproofing.


Dura-Son is a high-performance acoustic underlay that is specifically designed for use under luxury vinyl tile (LVT) floors. It provides excellent sound insulation and is also fireproof, making it a safe choice for your home.

Geniemat RST:

Geniemat RST is a rubber-based acoustic underlay that is ideal for use under hardwood, tile, and stone floors. It has excellent sound absorption properties and is also fireproof.

Impactomat 5:

Impactomat 5 is a heavy-duty acoustic underlay that is designed to reduce impact noise, such as footsteps and furniture movement. It is commonly used in commercial buildings and high-traffic areas.

Mutemat Range:

The Mutemat Range offers a variety of acoustic bases and underlays, including cork, foam, and rubber options.

These materials provide excellent sound insulation and are also environmentally friendly.

Soundproofing Products

In addition to acoustic bases and underlays, there are also other soundproofing products that can be used to further reduce noise transmission. These include acoustic foam, green glue, and tecsound.

Acoustic Foam:

Acoustic foam is a popular choice for soundproofing walls and ceilings, but it can also be used on floors. It absorbs sound waves and reduces echo, making it an effective solution for reducing noise in a room.

Green Glue:

Green glue is a viscoelastic compound that is applied between layers of drywall to create a sound-dampening barrier. It is commonly used in construction projects to reduce noise between rooms or floors.


Tecsound is a self-adhesive membrane that can be applied to walls, ceilings, and floors to reduce noise transmission.

It is made of a high-density synthetic rubber and is an effective solution for soundproofing.

Choosing the Right Materials

When it comes to soundproofing your floors, it's important to choose materials that are not only effective but also safe and durable. Here are some key factors to consider when selecting soundproofing materials:

Fire Rating

Fire safety is a crucial consideration when choosing soundproofing materials. Look for products that have been tested and certified for fire protection, such as the ASTM E84 test. This test measures the flame spread and smoke development of a material and assigns it a fire rating.

Sound Absorption Coefficient

The sound absorption coefficient (SAC) measures how much sound a material can absorb.

The higher the SAC, the more effective the material is at reducing noise. Look for materials with a high SAC, preferably above 0.75.

Class A vs. Class C Materials

Materials are also classified based on their fire rating and sound absorption properties. Class A materials have the highest fire rating and SAC, while Class C materials have the lowest.

When it comes to soundproofing, it's best to choose Class A materials for maximum effectiveness.

Installation Tips

Once you have chosen the right materials for your soundproofing project, it's important to follow proper installation techniques to ensure optimal results. Here are some tips to keep in mind:

Acoustic Ceiling Installation

If you are soundproofing a ceiling, make sure to install an acoustic layer between the ceiling and the floor above. This will help reduce noise transmission between floors.

Acoustic Insulation

When installing acoustic insulation, make sure to fill any gaps or spaces between the insulation and the walls or floors. This will prevent sound from leaking through and compromising the effectiveness of the insulation.

Fire Rating

When installing soundproofing materials, make sure to follow the manufacturer's instructions and safety guidelines.

This will ensure that the materials are installed correctly and do not pose a fire hazard.

Additional Tips

In addition to using acoustic bases, underlays, and soundproofing products, there are also other steps you can take to reduce noise in your home. Here are some additional tips:

Cork Subfloors

If you have hardwood or tile floors, consider installing a cork subfloor before adding your flooring. Cork is a natural sound insulator and can help reduce noise transmission.

Acoustic Subfloor Adhesive

When installing your flooring, use an acoustic subfloor adhesive to secure the flooring to the subfloor. This will help reduce noise caused by movement and vibrations.

Foam Underlay

If you want extra cushioning and comfort under your feet, consider using a foam underlay in addition to an acoustic base or underlay.

Foam provides excellent thermal insulation and can also help reduce noise.


To maintain the effectiveness of your soundproofing materials, it's important to keep them clean. Use isopropyl alcohol, neutral soap, or hydrogen peroxide to clean vinyl flooring, and cornstarch for acoustic foam.


Soundproofing your floors is an essential step in creating a peaceful and quiet environment. By choosing the right materials and following proper installation techniques, you can effectively reduce noise transmission and enjoy a more peaceful home. Remember to always prioritize fire safety and choose materials with a high sound absorption coefficient for maximum effectiveness.

With the right soundproofing products and techniques, you can finally say goodbye to unwanted noise and enjoy a more peaceful and stress-free living space.
