Heat Insulator

Helping your car keep its cool literally is easy by installing a high-quality heat insulator in all the right places. A heat insulator is basically an insulating mat you place all around your car's interior panels. With the right material attached to the floor, firewall, trunk, hood, under the roof, and door panels, a huge amount of heat released by the engine is absorbed. This will then help decrease temperatures under the hood and inside the passenger cabin, lessening the chances of overheating. And since temperatures inside the cabin are also pulled down, your car's AC won't have to work that hard to keep you cool. So if you want to enjoy the benefits of an insulator, here's what you need to do to install one inside your car:

Tools needed:

  • Cutter
  • Chisel
  • Pen or marker
  • Scissors
  • Seam roller
  • Knife
  • Razor blade (optional)

Step 1: Remove existing panels, trims, and factory fabric mats.

Depending on where you plan to install the heat insulator, you'll have to remove the seats, carpet, trims and trim panels from the floor and trunk, side panels from the doors, and the factory fabric mat from underneath the hood. If you're thinking of insulating every available surface, it's best to start with the floor and firewall since these are the largest areas. Because the right way to remove seats, panels, trims, and mats depend on your car make and model, verify removal instructions with your vehicle manual.

Step 2: Measure the mat against the sheet metal.

Because not all surfaces of your car's floor and firewall are flat and have the same measurements, you need to study the layout first to figure out how to cut the insulating material. Grab a sheet of insulating material and place it on the surface you want to cover. Press down to make impressions or indentations on the insulating mat's foil material so you'll have a guide when cutting out extra pieces. Using a pair of scissors, cutter, or razor blade, cut out the extra material.

Step 3: Attach the heat insulator material on the sheet metal.

Peel off the release or backing paper from one side and stick the insulator on top of the sheet metal. Work your way slowly across the insulating sheet, carefully removing the backing paper underneath the insulator. Make sure you apply even pressure across the insulating material. If air bubbles start to pop up, simply poke them out with a knife and press the material down with a seam roller.

Step 4: Repeat steps 2 and 3 until all surfaces are covered.

To cover all the other areas, repeat steps 2 and 3. The trickiest part is when covering bulky or uneven surfaces and hard-to-reach corners. Aside from measuring the heat insulator material directly against the sheet metal, you can also use a cardboard first. Then cut out the cardboard piece and use it to trace patterns on the backing paper. Simply follow the outline as you cut out the extra insulating material. Once you've cut out pieces of insulation, stick them in place while slowly peeling off the backing paper. Flatten those hard-to-reach corners with a chisel and remove air bubbles with the roller.
