Best Automotive Sound Deadening Materials Buying Guide

What to Look for Out When Buying a Sound Deadening Material

  • Is your chosen material odor free?

If you purchase sound deadening material that doesn’t stand up to high temperatures, prepare yourself for a smelly ride to work! Some material such as average polyurethane foam – no matter if it can tolerate substantial heat – still stinks to high heaven. We recommend purchasing closed-cell polyurethane foam to keep your car stench-free.

  • How thick is the material?

The thicker the material, the better the sound-proofing. The best kind of automotive sound deadning is 50 mils at least. If you really want to obtain professional results, there exists materials that are over 100 mils thick – Noico Solutions Car Waterproof Sound Insulation being such an example.

  • Does this product include rollers?

As you should know by now, an important part of the fitting process is rolling out sound deadening sheets before installation. It’s best to opt for a product that already includes rollers. If not, you’ll be undoubtedly disappointed having carved out a chunk of your time to fit only to find you’ll be making a trip down to the hardware store beforehand.

Benefits of Automotive Sound Deadening Materials

  • Play That Funky Music – By reducing the racket your car makes, you can turn your stereo up and only focus on good tunes and the road in front of you.
  • Good Vibrations – Spoiler alert: although the Beach Boys may dispute this following claim, there’s no such thing as good vibrations in a vehicle. Installing automotive sound deadening materials will reduce rattling significantly!

Best Automotive Sound Deadening Materials FAQ:

Q: How do I install sound deadening material?

A: Although the rumors that the right sound deadening materials will switch your driving experience up a notch, every success story includes a hard graft. Below lies a helpful guide on how to install sound deadening material the right way.

Important Hints and Tips

WEAR GLOVES – Remember, your safety should always come first! Foil liner runs the risk of cutting your hands into pieces.

  1. Measurement- Scope out the size of whatever part of the car you want to insulate first and then cut your material exactly to the measurements required. Don’t rush this process: the entire installation should take you around five hours to complete. All surfaces should be greased and degreaser before fitting these sheets.
  2. Application – Sticky adhesion should be applied to the spot which you wish to place your mats. Afterwards, press your pre-cut material firmly over the stick to ensure it holds perfectly. Some of the best sound deadening mats – such as Noico Solutions’ Sound Deadening Mat – features handy foil dimples that clearly show what spots need more pressing. You should also use a roller to roll down the foil to ensure that its flat.
  3. Protection – Once you’re rolled down the foil until its plain and smooth and the convex texture cannot be seen, it’s now time to spray within the cracks to make your mats have a firm hold. Now, all that’s left for you to do is bask in the glory of the near silence of your sound deadened vehicle.

Q: How do I remove sound deadeners?

A: Firstly, don’t let yourself be tricked into thinking that removal will be over and done with in five short minutes. This process – if you do it the right way – should take around an hour. There are two main ways to remove sound deadeners, yet we believe that heating and scraping the material is time-consuming and messy. Working with dry ice allows us to produce optimal results.

What You’ll Need:

You’ll require around 20 pounds of dry ice that you should sprinkle to cover the tar. Do not let this ice touch your skin – we recommend wearing gloves for each and every stage of the process.

  1. Remove all junk from your car floor – Do you have any wires, carpets, or random takeaway boxes littering your car floor? Clear it all away. Whatever the ice touches, it will freeze.
  2. Place the dry ice down – The layer of ice placed over the sound deadening should be around one chunk thick to obtain optimal results. Now, all you’ve got to do is be patient and wait for the popping and creaking noises to start from the chassis – otherwise known as the sound deadening breaking free from the body of your car.
  3. Smash the ice away – After scooping all the dry ice away to store for freezing the next section of your car, strike a small hammer down into the frozen tar. With some effort, it will start to crack neatly to the point where it can simply be lifted out. After removing ice from the accessible spots, carefully strike the delicate vertical locations in your car.
  4. Repeat the Process – Unless you’re a sound deadening removal expert, there will undoubtedly be spots that you’ve missed. Use the same process to do away with the small bits of tar that remain. However, this should be far less time consuming. Afterwards, all that’s left is clean your surface and sit back to admire your work!
