  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.
