10 Best Sound Deadening Material for Cars

Sound deadening material for cars is needed for those people who use local cars without luxury cars. Comparatively, luxury cars are better soundproof.

If you are returning home from your daily work in your favorite car or are on a road trip, then some unwanted road noise can disturb the quiet environment of your car.

Also, if you are listening to your favorite music inside the car or want to maintain the acoustic environment in your car, then the road noise or the sound of your car’s engine can be a problem for you.

That is why it is necessary to soundproof your car using some of the best soundproofing materials. Soundproofing materials help in reducing the outside noise and creating a quiet environment inside the car.

So let’s see what are the best soundproofing materials are and how you can soundproof a car using them?

10 Best Sound Deadening Materials

1. Flexible Tape:

Incredibly strong, waterproof, and durable rubber tape; it can be used to repair, seal, bond, and secure virtually anything.

2. Damper Pro:

The Damper Pro soundproofing mat is made entirely of butyl rubber and has an industry-high heat resistance of 232°C.

3. Dynamat Xtreme:

Strong, adhesive soundproofing mat that reduces heat, vibration, and unwanted noise.

4. Noico Soundproofing Mat:

Compared to 50-mil mats, this thick butyl soundproofing mat is 1.5 times more effective.

5. Noico Green Liner:

The Noico Green Liner car heat insulation pad is a water- and oil-resistant rubber foam pad, ideal for both heat insulation and sound absorption.

6. Hushmat Ultra Silver Foil Deadening Pad:

This soundproofing pad is excellent for reducing heat and is designed to eliminate road noise and vibration. The Kilmat 2.27m (80 mil) automotive soundproofing mat, made of foil and butyl pad, is ideal for reducing engine noise and loose metal.

Different Types of Sound Deadening Materials

1. Butyl Rubber Mats

Butyl rubber mats are one of the popular soundproofing materials. These popular rubber mats are known for their exceptional soundproofing properties due to their thickness and high-quality foil. This material is important for reducing amplitude, both aspects.

Butyl rubber does not contain fillers and has annealed foil through it. This product does not melt easily due to its strong resistance. If you want to cover the effects of noise coming from the exhaust, engine, and tires, then butyl material is the best option for you.

These mats, made of butyl rubber, are designed for various surfaces of the car. Such as floors, doors, roofs, and even the trunk can be applied to all these areas. It is effective in blocking noise when used.

2. Closed-cell foam insulation

Closed-cell foam insulation is an effective option for soundproofing.  These foams can effectively block outside noise and are also good at providing thermal insulation.

Closed-cell foams are made from polyethylene, which not only reduces noise but also retains water and is very suitable for shock absorption.

This type of foam insulation is already being used in many industrial applications, including construction and packaging.

To create an extra layer of sound insulation, you can place it in cavities, under carpets and even behind panels.

3. Woven fiber and foam insulation products

Woven fiber and foam insulation products are a good option. You can use these options under your car carpets and floor mats. Fiber insulation is the same stuff we use in our homes. 

Waterproof foam insulation is easy to find, but waterproof fiber insulation is harder to find.

Tools for Installing the Materials

To properly apply sound deadening materials, you need to use some methods to buff the metal. Some like Noico have textured surfaces that become flat when you buff them. 

Many people try to apply such materials with a round handle like a screwdriver or anything they have on hand. As a result, it is very difficult to install these materials properly. 

So the manufacturers of all these companies started using a special type of roller. 

1. Applications of Roller: 

As you know, you need to apply some pressure to get the self-adhesive back of the mat to stick to the sheet metal of the car. 

So on the outside of the car, such as the trunk or walls, your hand will easily reach them, so there will be no problem there. But in places where your hand will not be able to reach them very easily, such as inside the doors. In that case, a roller is needed to stick well. 

Nowadays, some manufacturers like Noico, Dynamat, and Uxcell add a roller to their products along with their products. Usually, these rollers are made of metal or rubber. The main purpose of this is to apply the material as smoothly as possible. 

2. Sealing Tape: 

In addition to wanting the sound deadening mats to be completely flat and smooth against the sheet metal, some people also want to cover the surface to complete their work. Although this is not necessary, you can cover it with a finishing tape. 

Some manufacturers now make their own soundproof sealing tape in addition to the rollers that come with the materials. These sealing tapes are not very thick, only about two millimeters thick. 

They are made of waterproof and non-acrylic adhesives, so they are designed to seal the joints between the pieces of mat you install. 

In this case, I have my own opinion that after installing the materials correctly, you do not need waterproof tape, and you can use it if you want, in which case it will not make much difference in terms of sound insulation.

Purchasing Guide to Buy the Best Sound Deadening Material for Cars

When choosing automotive sound deadening materials, there are a lot of sound deadening products available in the market, making it difficult to choose the right product.

It is very important to know what you need to consider when choosing the best product for different cars and trucks. After knowing this, it will be easier to buy the product.

1. Types of Insulation

You can insulate a car in two ways. You can use sound deadening techniques or you can use sound absorption techniques. You can use either of these two. First, you need to understand the difference between soundproofing and sound absorption:

Soundproofing is the process of preventing external noise from entering the car, such as road noise, traffic noise, wind, etc.

If your car is new and the car itself does not make noise, then you can use soundproofing.

2. Types of Materials

There are different types of insulation available in the market that absorb different levels of sound.  What materials to use for your car and you are aware of the materials. 

And you should be aware of this fact that the denser the material or the greater the mass of the material, the more effective this material will be in absorbing sound. You should know about the different soundproof insulation.

3. Soundproofing mats: 

These are common types of insulation materials that can be used to cover different surfaces in your car. 

Soundproofing pads: Also known as product insulators, these products are made of fiber cloth. This product is used under the carpet to block the sound from the bottom of the car, absorbing it.

4. Size

Before using DIY sound insulation in the car, you need to measure the size of your car accurately. All these materials come in roll form so that you can install them correctly in your car according to your size.

You can buy different types of sound insulation for your car, which you can install in different parts of the car.

 5. Weight

A car or truck has many corners and bends, which makes it difficult to install or use soundproofing materials in the right place. If you do not use too much heavy material, using lightweight materials will not waste your energy and labor time.

A car or truck has several corners and bends, which makes it difficult to fix the soundproofing material in place. If the soundproofing material for the car is heavy, then you can forget about doing it yourself. It is always recommended to choose lightweight soundproofing products. This will save you energy and labor.

6. Odor

There are many types of cheap materials that emit a lot of odor during the summer. Soundproofing materials made of cheap materials absorb dirt, mud, and withstand rough handling inside the car. 

So it is better to invest in odorless materials, even if they are a little more expensive. Because while buying all these materials, you have to keep in mind that it is installed all around the car.
