Dynamat vs. Dynaliner: 6 Key Differences

Dynamat (Amazon link) is well known for its sound-deadening properties, and it pretty much remains the first choice when it comes to soundproofing cars.

Dynaliner (Amazon link) is a similar product from the same brand, but it’s geared toward heat insulation. Still, they’re very similar, so which one should you buy for your vehicle?

Dynamat vs. Dynaliner

The main function of Dynamat is sound deadening and has low thermal insulation. On the other hand, Dynaliner is designed mainly for heat insulation, but it’s also good at soundproofing. Dynaliner is made of synthetic acoustic foam, while Dynamat is made of butyl rubber.

Both products will help keep noise away from your cabin and regulate temperatures inside. However, if you understand what each one does best, you’ll take better advantage of them. Here’s all you need to know about Dynamat and Dynaliner.

Dynamat is a sound dampener that absorbs unwanted noise, which leads to better sound quality. The recommended use of Dynamat is for soundproofing cars, but many users can speak for its utility when soundproofing rooms

Dynaliner, on the other hand, is a lightweight insulator. Experts recommend applying Dynaliner over Dynamat for heat blocking and regulation. It has proven to be quite durable on top of being crush and tear-resistant. Unlike Dynamat, Dynaliner was designed first for thermal insulation, but it can give you acoustic isolation as well.

Thanks to their asphalt-free material, neither of the Dyna products produces any odors. This is only one of the many things both products have in common, but a few differences set them apart. As you’ll see, they complement each other quite well.

Dynamat vs. Dynaliner

Dynamat and Dynaliner were designed with two different things in mind: heat and sound. However, both products have almost the same properties. Let’s look at their features in more detail.

Dynaliner Pros and Cons

Like Dynamat, this product performs quite well in keeping unwanted sound away. However, it was created first and foremost with heat insulation in mind.

The Dynaliner has been a top choice product for many years. It’s especially recommended for particularly hot areas. If you’re adding Dynaliner on top of your Dynamat, you’ll also be improving even more the sound isolation in your vehicle. Dynaliner is especially good at reducing low sounds such as engine hum.

Pros

  • Easy to handle
  • Soft stylistic surface
  • Easy Installation
  • Thick and strong adhesive
  • Great heat insulation
  • Decent sound deadening

Cons

  • Not as stretchy as some users might want
  • Paper tears easily along the edges
  • Expensive

Dynamat Pros and Cons

The Dynamat has terrific reviews—it’s rarely ever rated below four stars. And although this product has some downsides, the good mostly outweighs the bad.

Dynamat is mainly composed of sound deadening material with moderate heat resistance. The product is designed for your vehicle’s cabin, but it can be just as good for recording rooms. Here are some of the pros and cons of Dynamat:

Pros

  • Doesn’t hold moisture
  • Great for soundproofing
  • Dense material
  • Large sizes
  • Versatile

Cons

  • Expensive
  • Thinner than Dynaliner
  • Difficult to handle and cut
  • Poor heat insulation

Tips for Applying Dynamat and Dynaliner

Installing Dynamat or Dynaliner in your vehicle or room can be intimidating. Fortunately, experts have done and dusted this process a million times over and shared some valuable tips that should make installation a breeze.

Follow these tips to install Dynamat or Dynaliner without fuss:

  • Use heat Guns. Use a heat gun to heat the product before installing. Using a heat gun will allow the Dynamat or Dynaliner to be applied more smoothly, which will avoid pesky air bubbles.
  • Two layers are better than one. Applying two layers often enhances the product’s effectiveness. Experts recommend applying Dynaliner over Dynamat—both products will work together to greatly improve the sound insulation of your vehicle.
  • Glue down the edges. Edges of Dynamat and Dynaliner are prone to curling up. Using Hot Glue will help you keep them in place.
  • Avoid air bubbles. You can use tools such as a wooden roller to press down the mat and avoid creating air bubbles.
  • Take your time. There’s no need to rush the process. Going slow may save you from having to repeat the process and lose a lot of money.

Does Dynamat Reduce Road Noise?

Dynamat reduces road noise as well as noise coming from your car’s engine. The more layers of Dynamat you apply, the more effective it will be.

Your car’s speakers are essentially covered by a big metal box. Because metal can produce unwanted resonance, it makes for a rather bad choice of material to surround a set of speakers. Your car will not only reflect sounds coming from inside the car, but also the sound of the wheels against the road and anything else coming from the outside.

Dynamat aims to provide a more friendly environment for reproducing sound in your car—or simply to make it more silent while you’re cruising through rough terrain.

Dynamat is effective at reducing noise coming from inside and outside of the car across a wide range of temperatures. It has a heat resistance from -65F to 300F (-54C to 149C). However, for it to work optimally, the temperature should sit around 14F to 140F (-10C to 60C).

Final Thoughts

If you’re stuck between these two products, you don’t even need to break a sweat. Both the Dynamat and liner are great products that perform at their best when they’re working together.

If you can get both, then go ahead. If you can’t, then you’ll have to choose what to prioritize: heat insulation with Dynaliner or sound deadening with Dynamat. It’s a good idea to apply Dynalyner on top of Dynamat, so if you’re not sure about which one to get first, go with Dynaliner.
