Soundproof Flooring: The Best Soundproofing Materials on the Market [2024]

Soundproofing your floor is a must especially if you live in an apartment building or condo with an upstairs neighbor. 

You may even want to soundproof the floors in your homes too.

Maybe you have a home theater or office in your basement or under your bedrooms, these are scenarios where you will want to install some soundproof flooring.

However, soundproofing a floor may not be as easy as you think.

So how do you soundproof your floor in an easy and cost-effective way?

Soundproofing carpets and flooring materials are pretty common on the market. 

While these may be able to muffle some of the sounds, they may not be ideal and will not provide the level of soundproofing that you need. 

In this article, we will talk about soundproof flooring materials that will drastically reduce noise levels traveling through the floor. 

For the steps on how to soundproof flooring, read our soundproofing between floors post.

Soundproof flooring materials and products

  • STC Rating: 66
  • IIC Rating: 67
  • Thickness: 3mm

Soundproof underlay is a type of material that is applied over the subflooring and is then covered by your final flooring.

You will find most underlayment materials are made from cork sheets, vinyl, rubber, and foam.

The Roberts Super Felt Underlayment is a high-performance underlayment that can soundproof floors and cushion flooring.

It is made from recycled fibers which are then compressed through a high heat manufacturing process.

This process allows this product to be the perfect material for absorbing noise instead of acting as a surface for noise to reflect off of.

This soundproof underlay is dense and works great for laminate and engineered floors.

With 3mm thickness, this material has insulating properties which means that it can keep your cold floors warm and toasty in the winter and cool in the summer months.

It comes with a film overlay to protect your floors from any moisture coming from the subfloor.

Also included is a 1 3/4 inch adhesive strip for fast and easy installation along with a 3-inch overlap in the event you want to link this roll to another.

The Robert’s Super Felt Underlayment comes in a 360 sq foot roll.

  • STC Rating: 66
  • IIC Rating: 71
  • Thickness: 3.1 mm

The QuietWalk Plus is very similar to the first product we’ve mentioned in that it is the ideal material to help reduce sounds traveling between floors.

This product works with laminate, hardwood, and engineered wood floors as well as other types of flooring to deliver great soundproofing properties.

It comes with a moisture-resistant vapor barrier that bonds well with a variety of adhesives to make the installation process easier.

The installation process is pretty fast and trouble-free since the material is easy to cut and rolls out and lays flat without rolling back.

This durable product is made from synthetic fiber that will not tear and is Greenguard certified due to the material having no petrochemical smell.

The fibers capture sounds and do not allow them to bounce around or travel between floors.

This underlayment also protects your floors covering material from thermal shock.

It does this by allowing the heat to permeate and distribute that heat evenly throughout the floor.

The  QuietWalk Plus underlayment dimensions are 36 x 9 x 9 inch

  • STC Rating: 66
  • IIC Rating: 68
  • Thickness: 2.0 mm

It will reduce ambient noise and help to correct any minor imperfections in the subfloor.

This product is ideal for laminate and engineered hardwood floating floors in condos and multi-level dwellings.

While thinner than the previously mentioned underlayment, this product is still thick enough with an STC and ICC rating very close to the others.

Like the previous Robert’s product, this unit comes with an adhesive strip and a 4-inch overlap strip if you will be using more than one roll.

The Robert’s First Step Underlayment comes in a 630 square foot roll measuring 15.5 x 15.5 x 39.5 inches.

Types of floor sound deadening materials to reduce noise

best floor soundproofing material stops annoying sounds

Floor sound deadening materials can be identified by the various types which are listed below. 

To install and make use of these types of materials read this how to soundproof a floor or how to soundproof a room post.

Acoustic Underlayment 

Acoustic Underlayment is a type of soundproof flooring that uses special materials that can be laid over concrete or plywood subfloors to cushion the floor and reduce the effects of airborne and impact noises. 

Sound Deadening Vinyl 

Sound Deadening Vinyl also called Mass Loaded Vinyl is usually made from a thin but heavy vinyl sheet. 

This special type of vinyl can dampen sounds in various places including floors, walls, and vehicles. 

You can slip some of this under the best quiet treadmill if you’re living in an apartment and your downstairs neighbor complains when you work out.

Sound Absorbing Floor Insulation 

Sound Absorbing Floor Insulation will include any type of acoustic insulation that can be stuffed between floor joists. 

They will need to be placed immediately below the subfloor to help minimize the amount of sound that travels between floors. 

Soundproof flooring insulation material can also be used from the ceiling on the floor below. 

Acoustic Floor Tiles 

Acoustic floor tiles are a special type of floor tiles that aims to reduce echo and reverberations in rooms with many hard surfaces.

While in use on floors, they provide a soft surface to absorb sound instead of allowing them to reflect and reverbs around the room. 

Sound Absorbing Carpet Padding 

The market is flooded with cheap carpets that claim to have soundproof properties to minimize noise between floors.

However, these aren’t what you should be looking for if you want to drastically cut down the amount of noise you hear. 

You will need a carpet with a thicker pad and high pile to achieve maximum soundproofing properties the denser the carpet the better it will be at absorbing noise.

What to look for when choosing floor soundproofing materials

soundproof underlay reduce footfalls

When choosing floor soundproofing materials, there are a couple of things you need to remember.

Below we’ve discussed these factors in detail to help you make a better choice.

Be sure to check these ratings when on the hunt for soundproof flooring materials.

Sound Transmission Class Rating

Sound transmission class rating or STC rating is the numeric rating that is applied to products to let you know how good the product is at blocking airborne sounds. 

The higher the STC rating the better the product is at soundproofing and should be the first thing you need to look at when choosing a floor soundproofing material. 

Impact Insulation Class Rating

Impact Insulation Class Rating or IIC rating shows how well the flooring material performs the block out impact noises.

In this instance the IIC rating will help to block impact noises like footsteps but also the moving around of furniture etc. similar to the STC rating the higher the IIC rating the better.

Thickness and density 

To effectively block sounds and reduce the amount of noise between floors mass matters. 

The thicker and denser your material the better soundproofing properties the product will have. 

This is because sounds would not be able to pass through a thick material as easily as they would with a thinner one.
