Sound Proofing

[gc91754]

I want to improve the noise reduction around the doghouse in my 2021 Winnebago Sunstar 29V, with the Godzilla Gas Engine…looking on Amazon and YouTube…for material and installation… Anyone have suggestions? Should I leave the undamaged liner already on there by Ford and add more insulation on top??? Should I worry about the Floorboards Driver and Passenger side???
Any experience with “DynoMat”???

I would remove the existing material to ensure a good bond of the new to the doghouse. I would also add the sound material to the floorboards as well. Will not only cut down on the noise but also help to reduce the engine noise. I havce not used the Dyno Mat although I have heard of it.

"DYNA-MAT" is a fantastic product. I installed it, 2 pieces, one is insulation, the other heat reflection.
Each is about 1" thick and has tremendous adhesive backing. Put the pieces together and installed to the existing insulation on the motor box (dog house) cover on my 2020 Newmar Canyon Star. What a difference it made.
Sold the coach last May, had 32,000 miles on it and was 5 years old, and all the insulation was still attached, as the day I installed it!
Classic car builders use it, and I now have a 1966 Pontiac GTO with the same product attached to the interior floor & trunk, and it is great!
The product can be cut, trimmed, etc, with an Xacto or razor type knife, & is fairly pliable. You can buy a "roller" with it, and use it to pressure roll the product into conformation of your flood, motor box etc!!
