As you continue to work on the acoustics of your vehicle, you’ll eventually wonder if it’s worth including firewall insulation. Let’s talk about the main reasons to soundproof a firewall, why you should consider doing it and how to use the firewall sound deadener.
When you are driving in your car, you are subject to major squeaks and noises. Many of them come from the car engine and suspension, but you might also hear road noise and other audible sounds. To correct this issue, you begin by sound deadening the floor. You know the importance of treating the doors and floors to get rid of major sounds, but an often overlooked area is the firewall.
Aside from reducing sound in the cabin, firewall heat insulation keeps the temperature down for optimal comfort. By providing a layer of material between you and the engine space, you effectively reduce the amount of heat that makes its way into your car or truck interior.
Here is a quick review of the most common benefits of installing firewall insulation:
- reduces noise;
- reduces heat;
- increases cabin comfort;
- improves the sound of car stereo equipment;
- simple to do and easy to install (no experience necessary).
The best time to install automotive firewall insulation is when you are already working with the floor. At that point, you already have everything removed and ready to go.
Follow these steps for proper installation:
- 1.Unplug the battery.
- 2.Remove everything covering the floor and firewall. Make sure you take out the carpeting, seats and put all your hardware in a box.
- 3.Put all your hardware in a box.
- 4.Mark all the wiring with stickers so you can put it back together correctly.
- 5.Clean the floor with a vacuum and then degrease the surface.
- 6.Cut out a template made from cardboard.
- 7.Line up your pattern and make sure all the holes match perfectly.
- 8.Heat the backside of sound deadening material. Apply it to your firewall and floor. Get as far behind the dashboard as possible.
- 9.Press that material with a roller to keep air bubbles from forming.
- 10.Install the material in sheets back to back. This keeps moisture out of the car and deadens the sound better.
- 11.Install the layer of heat and noise insulation material over the sound deadening mat. Minimize thickness on your interior trim and under the pedals, but otherwise, remember to keep the mounting spots thin or completely cut out for reinstallation of your interior pieces.
- 12.Put your car back together in reverse order.
