Yes but I have used Dynomat and Fat Mat extensively in my RV and they do dampen much better than Frost King. Each has its purpose and it depends on the overall results you are trying to achieve. I have elimininated ALL heat from the dog house and surround areas with both Dyno and Fat. With the Air con running in cab the dog house is cool to the touch at any given spot. Even after 4 hour + trips its still cool. Im impressed. Sound level have dropped dramatically as well.
