## Description

Thermo-Tec 14620 60" X 36" Heat and Sound Suppressor

Review: Works great on my K5! - I recently purchased a sound deadening mat and I am extremely satisfied with my purchase. The mat is made of high-quality materials that effectively reduce road noise and vibrations in my car. The mat is also very easy to install and it fits perfectly in my vehicle. It also helps to improve the overall acoustic environment of my car, making it more comfortable to listen to music or have conversations. The mat is also very durable and it will last for a long time. I appreciate that it's a eco-friendly and cost-effective way to improve the sound quality of my car and also it helps to insulate the car, which keeps it cooler in the summer and warmer in the winter. Overall, I highly recommend this sound deadening mat to anyone looking for a cost-effective and easy-to-use solution to improve the sound quality and comfort of their car.
Review: Great Quality-Enough for my 2003 Expedition - I used this to replace the thick, sound deadening material that was OEM in the transmission tunnel. There was enough to cover all the way back to the end of the tranny and up the front firewall. This was great, it gave me a lot of room to reinstall the engine and transmission. It also looks a lot cleaner. Sounds quieter and the cabin runs cooler. I really like this product. Easy to install, forms well to all the bumps in the tunnel, bought tape to help seal the liner when I need to slit the material and mold to the tunnel. Six months later (after the rebuild) everything is still in place fine. I did a good job cleaning the metal to prep for the install, applied Thermo Tec 12005 adhesive, and used a roller to press the material against the metal. It should hold up if you prep correctly.

## Features

- Great for areas like firewalls, floorboards or doors
- The Suppressor is also 70 mil in thickness, contains a high temperature adhesive backing and is easy to trim and fit

### ⭐⭐⭐⭐⭐ Great Quality-Enough for my 2003 Expedition
*by B***E on December 29, 2019*

### ⭐⭐⭐⭐ Outstanding Sound Deadener, good radian Heat shield, but vague marketing material
*by J***S on September 2, 2012*

I have used another, much more expensive, brand of sticky-backed rubber as sound deadening material. The price for this product is consistently below other products offering the same or similar sound deadening properties. Regarding application, the product's adherence strength is proportional to the rubber's temperature. Thus, you could use a heat gun during application or simply let the product sit in the sun for 5 to 10 minutes just before installing the product. The later option makes it more difficult to work with, but if you only remove the wax paper over the sticky material as you move through installation, it reduces the difficulty and frees up a hand. As mentioned above, this product is priced below the average price of sound deadening material; thus, the heat shield is a bonus. Nevertheless, since Thermo-Tec pushes the heat aluminum heat shield, it's part of the product to review. I have noticed a modest decrease in both direct and indirect heat. Thus, no complaints there. However, I gave the product 4 stars because Thermo-Tec does not give, for instance, examples of the estimated heat decrease in typical installation scenarios. Rather, the packaging merely states that it "protects from radiant heat" on the packaging. Failing to provide more specific and meaningful information concerns me because I, at least, like making purchasing decisions on facts, not supposition. Caveat emptor. Moreover, Thermo-Tec provides this type of information for some of its other heat resistant products. Why not this one? Thus, I would recommend the product simply on the sound deadening properties, but I do not like the vague marketing approach of Thermo-Tec.
