Dynamat Installation – Eliminate Road Noise

You’re on a Dynamat installation mission.  You want to eliminate road noise, noise from outside the vehicle, and all sorts of little vibration and resonance noises that penetrate the cabin of your car, truck or SUV.  If you succeed, you’ll achieve the “nerve calming quiet” that a lot of luxury car makers charge top dollar for. The following is a Dynamat installation guide using a 2005 Ford Escape which details the tools you need and steps you take when installing Dynamat Xtreme series products.

Here’s a quick guide to sound-proofing your vehicle with basic materials and tools.

Three layers to quell the noise.

There are three layers to a complete sound dampening system in a vehicle:

  • Your first layer will be a mass adding layer that will adhere to the metal surfaces of your vehicle under the carpet, panels, and head liners. Adding mass will change the resonate frequency of the area it is attached to making it harder for that area to create noise.
  • The second layer is a closed cell foam that sits on top of the added mass layer. It’s job is to help absorb rattles, high frequency noises, and make it tougher for these unwanted sounds to travel into the vehicle’s passenger cabin.
  • Your third and final layer is a mass loaded vinyl. Think of this as a sound blanket that absorbs sounds.

Now that we have an idea on how each layer works, let’s look at what products to use and how to properly install them.

Dynamat Xtreme – First Layer

Dynamat Xtreme is sold in several different box sizes. How much you need can be difficult to measure out due to the many curves and contours in a vehicle. Most passenger cars will require at least one Dynamat bulk pack to complete the firewall and floor. Another bulk pack should handle your doors. The trunk in most vehicles will require a bulk pack also. The material it self is a very thin 0.67 inches thick but do not let that fool you. This product will do it’s job of adding mass to what ever metal panel you adhere it to.

Once you have your Dynamat Xtreme I recommend the following tools for your Dynamat installation:

  • A razor box knife along with several blades is one of the most important
  • I suggest a good tough pair of gloves
  • Dynamat roller
  • For cleaning the metal surface clean rags and acetone will be your best bet
  • A shop vacuum to get any loose debris is very helpful
  • Last but not least always wear safety glasses

Taking the vehicle apart will be the hardest part of the installation. Good places to find out how to do this is in internet forums for your particular vehicle. Also Youtube has a large volume of front door, rear door and seat removal videos for common car and truck makes and models.

With the vehicle taken apart and the metal floor exposed we can get started.

TAKE NOTE: Most newer vehicles have a sound/heat pad glued to the floor. You can leave this if desired and install the Dynamat Xtreme around it not over it. For more advanced installers you can use a wire wheel on a grinder and remove it. After removal touch up the bare metal with paint and then install over the new dried paint.

Before Dynamat Xtreme is installed, the surface must be cleaned. Vacuum the exposed metal surface to remove all loose debris. A good way of working is to start at the firewall area on the driver side of the vehicle and get it wiped down using rags and acetone. You can then install the Dynamat Xtreme in this area. After that area is complete, wipe down the driver side floor area and install.

Your main goal is to try and cover exposed metal surfaces. You can overlap your pieces on one another if you have to. Most installers will take a full sheet from a bulk pack and place it into the vehicle with the back paper still on the adhesive side of the Dynamat Xtreme. They eyeball the correct size they need and use the razor knife to cut it to size. It is then as simple as peeling the back paper off the adhesive side and sticking it down to the metal surface you just cut it for. Once it is stuck down they then use a Dynamat roller to get a complete application adhesion.

Dynaliner – The Second Layer

Now that the first layer of Dynamat Xtreme is installed we can move onto the second layer. As with the Dynamat Xtreme the Dynaliner has a paper back covering the adhesive. The product is installed by simple sticking it over the Dynamat Xtreme’s silver top after being cut to size with a razor knife. Dynaliner comes in three thicknesses. The 1/8” Dynaliner is great for door panels and head liners to help stop noise and rattles. The ¼” Dynaliner is a great choice for quarter panels and fender areas. The ½”Dynaliner is also used on quarter and fender panels in which there is room to not interfere with the panel’s decorative trim panel to be re-installed.  Some people will also use it on the floor but there is a better option Dynamat has supplied for the floor in which we will cover in the third layer. Below is a door from start to finish as it is very difficult to get the third layer of vinyl on most doors so most installers stop at the second layer.

Dynapad – The Third Layer

Finding the correct mass loaded vinyl for sound dampening installations used to be a challenge. I say used to because Dynamat has brought to the market the Dynapad.  This is a ½” Dynaliner with a mass loaded vinyl sheet glue to it ready to be installed. Dynapad is sold by the sheet and each sheet is 12 sq. ft. It is used mostly on fire walls and floors. It has no adhesive backing and is heavy enough to be simply laid down over the area of install. Some installers will use duct tape to help hold it in place on the fire wall and floors. It can be trimmed to size with a razor knife just as all Dynamat products can. Be sure to trim holes in the Dynapad for seat bolts and other mounting locations to make for easier re-installing of the vehicle’s interior. Below is Dynapad installed over Dynamat Xtreme on the floor.

Dynamat not only helps with noise but also adds a layer of insulation to the vehicle. The benefits out weight the cost and time it takes to install. Dynamat products will last the life of most vehicles and helps your stereo sound better and for you to enjoy a quieter ride. It can be done in stages such as your floor first, doors second, or vice versa. Get a pack and give it a try. Most people are blown away by how well it works!
