Best Sound Deadening Materials for Cars
Mats, pads, and sprays have been developed for soundproofing cars. The best material is debated below. If you aren’t fortunate enough to have an electric car, then you might notice high levels of background noise. This is especially true for those with older vehicles that are in need of an upgrade.
One of the solutions to this that won’t cost as much as a new car is to install sound-insulating material on the inside of your vehicle. If you are interested in finding the highest quality of sound-deadening material and how to block loud road sounds, you might want to consider applying some of the material paneling below to the interior.
The added benefit of sound-absorbing material is improved temperature regulation. Insulating any place to make the sound less overwhelming and easier to handle can help retain heat and keep any space warmer for longer.
Sound blockers and absorbers are somewhat interchangeable in terms of their sound-absorbing capacity. That said, they slightly vary in their properties. Sound absorbers can help soften noise, whereas blockers focus on creating a barrier between your car and its exterior.
Sound-deadening material comes in different product types. These include mats, woven products, and even spray. The material is often known as acoustic foam and is most commonly seen in the form of adhesive padding that can be trimmed to fit a certain area.
The spray is one of the last resort products that is used for more difficult areas, such as hard-to-reach panels or awkward shapes. Sound insulation materials can vary in thickness, size, and main material features. This is a guide covering some of the best materials and products that are on the market.

Butyl vs Rubber Asphalt
Some of the more commonly used materials within the theme of soundproofing panels are rubber and butyl. Each has its own selection of pros and cons, which is why it can be difficult to determine which type of product and brand to use.
Butyl has been designed to withstand much higher temperatures than rubber, and panels stay much more sticky for longer. This is because of the synthetic reinforcements of the material that have been developed to withstand more extreme conditions. For that reason, many consider butyl as the better material for sound deadening in cars.
Some have gone as far as to criticize rubber pads for creating a scent that is off-putting and arguing that it is a less efficient material. That said, it is worth considering that rubber mats and sound-deadening padding are extremely affordable.
It is also the preferred material for those who like to incorporate more natural materials into their life, as natural rubber can be sourced. On the whole, however, many reviews highlight the role of rubber padding is very thick and somewhat inflexible.
When compared to butyl, asphalt is the less reliable choice, and it is more vulnerable to damage and even melting during more extreme temperatures.
For that reason, it is not recommended that you invest in rubber pads for soundproofing if your vehicle is prone to overheating, as the smell of melting rubber can be very potent.
There has also been some level of debate about whether the thickness of the material is more important than what product is used. Obviously, thicker padding helps to create a better sound barrier and absorb even more background noise.
However, there is a lot that the core material brings to the table. Rubber provides less option for thickness, as it naturally comes in a predetermined width. It is more difficult to cut to size and install. The natural winner of this debate seems to be butyl.
While it is more synthetic, there is less odor to butyl, and it is more resistant to heat. This is a particular advantage when it comes to use within a vehicle.

Which products gave a smell?
Products containing asphalt are some of the most common things that can create an unpleasant scent that can result in headaches and even dizziness. It might be worth avoiding any products that list asphalt as an ingredient if you are prone to substance-related reactions. It might also be worth considering that some rubber-based products have a rubbery scent upon initial application. This might be off-putting for some people, and it is definitely something to be aware of.
Should I layer sound deadening material?
Some brands encourage this. Because of the nature of these insulating materials, additional layering creates a bigger platform to absorb more background noise.
If your car has a particularly loud engine, or if it’s closer to the ground and picks up a lot of additional noise, you might want to consider carefully adding a second layer of sound protection. That said, you can achieve similar effects by taking the time to ensure that all possible areas have a panel of sound-absorbing material.
Final Thoughts
Hopefully, by now, you have a better understanding of soundproofing and how to prevent unnecessary noise from entering your vehicle when you’re on the road. There are many advantages to integrating soundproof panels into your car, from preventing the noises of other cars from irritating you, to making your music easier to hear.

There has been some level of debate surrounding the effectiveness of different products, which is why a range has been highlighted above. The role of customer reviews and brand specifications are some of the most important factors that have determined their usefulness in soundproofing.
Thicker materials are able to absorb more sound from the background and even your engine, but things to consider include the material used and whether you want to invest in a more reliable option or use affordable rubber-based pads.
Butyl is the dominant material across soundproofing means, because it is more resistant to temperature changes, has less of an odor, and can be cut into shape and installed much easier. It has been designed to last longer in comparison to rubber. This means that it could be worth installing.
