Automotive sound deadening materials not only have their fair share of individual specifications, but they can also be quite expensive. Because of this, buying materials that don’t end up working for you can be a frustrating and costly mistake.
Fortunately, these problems are easy to avoid with the right amount of research. Below, you’ll find everything you need to take into consideration before spending your money on a soundproofing material.
How Thick the Material is :
When it comes to sound deadeners, thicker materials provide better sound insulation.
So if you pay extremely close attention to every sound, or the slightest bit of road noise bothers you, then finding a material with a high amount of thickness is ideal for you.
Most sound deadeners consist of about 50 mil thickness, with 80 mil being extremely good. However, the amount can get even higher.
There are some materials with thicknesses of over 100 mil.
Does Heat Impact the Material? :
Several sound deadeners don’t react well with the heat, which makes them big no-no’s for people living in warmer climates.
When these deadeners come in contact with high temperatures, their materials can melt, leave behind bad odors, or more.
However, soundproofing materials with adhesive tend to work well in hotter weather, with the heat not having a significant impact on their effectiveness.
Is it Odor-Free? :
As mentioned earlier, materials that don’t do well in high temperatures tend to leave behind foul odors when exposed to the heat. However, that doesn’t make them the only materials that can produce a smell.
Many materials produce strong odors during the installation process and even after the adhesive has been applied. While this only lasts for a limited period of time, it still isn’t a comfortable situation.
Plus, some materials have a constant odor, even if faint. For example, a few are known to have the scent of a newly paved road.
Rollers Aren’t Always Included :
To ensure sheets will perform at their best, it’s important to roll them out before applying them to the vehicle.
While several products include these rollers, many others don’t, which means you’ll have to buy one separately before you’re able to use the sheets.
Questions & Answers
Now that you know what to ask yourself when shopping for sound deadening materials, you probably have a few questions about how to use it and where it can be used.
We’ve put together a collection of commonly asked questions and answered them so you know exactly what you need to know when your sound deadener is delivered.
How to Install Sound Deadening Material?
Sound deadeners come in four different forms:
Each form has a different method of installation, and are best fit for different areas and spaces of the car. For example, insulation is made mostly of fibers and works best for the roof and doors, whereas mats are ideal for the panels, floor, and doors.
The amount of material you use depends on how much noise you want to deaden. If you’re hyper-sensitive to road noises, you’d want to use more materials than someone who simply wants to make them a bit quieter.
The method used to install the material depends on where you’re putting it.
Floor : – remove the carpet, then clean the floor thoroughly. After the floor is cleaned, apply the deadener. Once applied, put the carpet back on.
Roof :- remove the cloth headliner and clean the roof with rubbing alcohol. Apply the sound deadener. Put the headliner back in place.
Trunk : – remove any items you have in the trunk and any floor fabric or carpet. After cleaning the trunk, apply the material.
Firewall : – dismantle the dashboard and then clean. Apply the deadener and then reassemble the components you dismantled.
How to Remove Sound Deadeners?
Just because a sound deadener is easy to install doesn’t mean it’s easy to remove. In fact, this is the case for many products, especially those that boast easy installment.
While the amount of time it takes to remove the material depends on the type of car, the process shouldn’t take more than an hour when using the proper tools.
Using about 20 pounds of dry ice, sprinkle enough to cover the tar. Afterward, lightly tap it with a rubber mallet or small hammer.
Many people result to heating and scraping the material. However, not only does it take a lifetime to remove, but it also makes a huge mess.
Concluding Thoughts :
Car rides should be enjoyable and peaceful, and a fun time listening to your favorite music shouldn’t be interrupted by road noise.
And the great thing is, a high-quality solution doesn’t have to expensive or difficult to install. Investing in an automotive sound deadening material is one of the easiest and most cost-effective ways to soundproof your vehicle.
