Product Description

Thermal Block - 1 Sheet - (24" x 36") = 6 Sq Ft. - Radiant Heat Reflector

*Made In The USA*

Thermal Block is a peel and stick mat made of highly reflective foil and organic fibers designed to face the heat source and reflect radiant heat. This 3 layer composite heat shield should be installed on the engine side of the firewall, transmission tunnel or under the car and above the exhaust. Thermal Block is made of a reflective aluminum surface, a non-needled, non-woven carbon fiber insulation layer and a high heat pressure sensitive adhesive.

Surface must be free from oils, dirt, dust, powder, or grease contaminantsInstall at temperatures of 65 degrees F or above. 

Sheets Size = 24" x 36" (6 sq. feet)

Thickness = 1/4"+/- (.25%)
Mass/Area = .175 lbs per sq. foot
Total weight per sheet = 1 lbs +/- .25lbs

Typical Places of Use:

  • Engine Side Firewall
  • Undercarriage 
  • Hood 
  • ATV/Jet Ski/Snowmobile - Under the seat or above the engine which usually is below the rider.  
  • Back Seat Wall 

Noise Reduction Uses

By nature, anything placed between the source of the noise, and the passengers, will, to some degree, reduce noise. This product has an organic fibrous core, which will reduce some airborne sound waves. When placed on the engine side of the firewall, not only will it reflect heat, it will also reduce some of the engine noise.

For best acoustical results using this product, first apply a layer of our Damplifier Pro vibration mat on the engine side of the firewall, and then apply this product on top of it to keep the heat out.

Thermal Insulation

This self adhesive barrier is designed to face the heat source to reflect radiant heat and dissipate convectional heat up to 800 degrees f.
This composite mat has 3 layers of high quality thermal insulation for the ultimate in automotive thermal insulation.


Is Thermal Block self-adhesive?

Yes, it utilizes a high heat peel and stick adhesive. 

Where NOT to install Thermal Block?

The interior of you car is NOT a good place to install Thermal Block as it must be facing the heat sourse.

  1. Great product 5 Star Review

    Posted by on 12th Aug 2016

    Adheres well to clean surfaces. Super thin for what it does, great for low clearance areas. Requires nice sharp tools for cutting, it is a strong fiber. Gloves are helpful to avoid cuts while installing.

  2. Works really well 4 Star Review

    I ordered the thermal block for my Pioneer 1000 sxs due to the heat from the motor. After applying the product the heat no longer is unbearable coming from the area between the seat and the seat back. I actually ordered more for another area. Highly recommend.

  3. Cooled down the Side By Side seat 5 Star Review

    Posted by on 23rd Mar 2016

    Added this to the seat panel in a new side by side. It substantially lowered the heat coming through the plastic panel. Product was easy to work with

  4. Unbelievable Performance 5 Star Review

    Posted by on 16th Nov 2014

    This stuff is the size, shape, and weight of a piece of cardboard. I used it to insulate the trunk of a mid-engined sports car. The trunk was affectionately known as "the oven". I removed almost all of the factory insulation and used Thermal Block as directed. The trunk stays cool now, much better than before.
