This heat shield insulation material is easier to install than exhaust wrap, it also reduces more heat from your exhaust pipes and components. Heatshield Armor™ which can stop exhaust heat up to 70 percent and it is much easier to install.

The outer armor of Heatshield Armor is resistant to the elements is a 4 mil this aluminum, giving the exhaust heat shield a long life. We our exclusive BioCool insulation material as the inner pad, bonded to a heavy-duty foil outer layer using a proprietary process. This makes it capable of withstanding 1,800 degrees F continuously, which allows this heatshield to be placed directly on exhaust systems, turbo manifolds, downpipes and diesel particulate filters (check with state regulations regarding usage on DPF). Because this heat shield installs directly on the exhaust system components, it performs better than the clamp-on standoff heatshields that allow heat to escape because they are set above the pipe and not directly insulating it.

Heatshield Armor also offer superior performance over an all metal exhaust heat shield. The all metal heat shields have conduction with one hot side and one cold side: With Heatshield Armor, there is no metal-to-metal contact layer it uses a thermal break to create real cold side on this heat shield.

BioCool is a non-caustic, non-flammable bio-soluble silica thermal insulation material. It does not cause itching and won’t smoke or smell the first time it is heat-cycled. This exhaust heat shield material is flexible, easy to cut (you can use a pair of heavy-duty scissors) and may be cleaned after installation. Heatshield Armor is available in two thicknesses: 1/4-inch for most naturally aspirated applications and 1/2-inch for forced-induction and racing applications.

This calculator is a tool to estimate how much exhaust heat shield wrap you will need for your exhaust system. Calculations are a guide only! While this calculator is very accurate, results will vary on installation of Heatshield Armor. By using this calculator your agree that this is a guide only and that actual usage may vary.

Guide for calculator usage:

All fractions should be in decimal form, for example:

  • 1/8 should be 0.125
  • 1/4 should be 0.250
  • 1/2 should be 0.500
  • 3/4 should be 0.750
  • 7/8 should be 0.875


1/4" is reccomended for naturally aspirated automotive applications and powersports. 1/2" thickness is recommended for all forced induction automotive, heavy duty, genset and industrial applications.

Q. Do I need tin snips to cut Heatshield Armor?

A. No tin snips are not necessary, heavy scissors or utility knife  cut it just fine!

 Q. I'm trying to determine the number of ties I will need to order for securing the Heatshield Armor to my exhaust pipe. What do you recommend for spacing between the ties? Thanks

A.  For straight using Thermal-Ties every 6-8” is good, for tight bends in pipes, every 3” usually works. Be sure you are using the wide ties as they grip the armor better.

 Q. Does the Weld Tape hold the Heatshield Armor in place? 

A. No weld tape does not hold in Heatshield Armor in place. We recommend our heavy duty Thermal-Ties, they have 45% more gripping power than most ties on the market. You can also use a hose clamp, safety wire, or other mechanical fastener to hold in it's place. The weld tape is uses to make repair any damaged to the armor layers. The weld tape is not to touch the exhaust directly, should only be used on cold side applications.

 Q. Why are there shields that are clamped on but don't touch the exhaust like the Heatshield Armor? Do they work better?

A.  Aluminized exhaust heat shields, need air space so they can reflect radiant heat away, so they are not designed to lay directly on the exhaust. As far as the other basalt shields that don't directly touch the exhaust, we have no idea. Sometimes it isn't good to copy another design and over think it, try to do something original. Heatshield Armor will stop the most heat from radiating up from the pipe, period. You can trim it to cover just the top half or ¾ of the pipe instead of using a stand off heat shield, this way you trap most of the heat at the source, you don't have an air gap and try to indirectly divert heat, direct diversion works better. Physics doesn't lie, the most efficient way is to manage heat directly at the source.


Use Heatshield Armor on:

  • Exhaust Pipe Heat Shield
  • Muffler Heat Shield
  • DPF (check with state regulations)
  • Catalytic Convertor
