The denser insulation dampens out lower frequencies, bass, maybe some of the exhaust resonance. It doesn't require as much thickness of it to get the same mass as the fluffy stuff. Plus 1/4" of it would really add weight.
I put 2 layers wannabe dynamat in the front half of my car, kinda wish I hadn't. I think the seller called if fatmat. It basically added 10 lb to the front half of the car, minor carpet/trim fitment interference from added thickness, and it will never come back out without a massive mess. Results are dubious. I believe the product is actually called peel n seal, used for waterproofing shower membranes. It is a thick tarry film on a roll with foil covering.
I think the doors are a big source of noise. There is a product that goes inside the door panels I might try, for various other reasons, including quieting any minor rattles from all the stuff in the doors.
And I assume you're running the fiberglass top with headliner, not the ez bake top.
Thx for the good comments about your experience greatly appreciated . Carpet trim/fitment is a big concern for me. I’m surprised you went with a double layer in the front and if we ever want to remove it, a massive mess would not be my first choice.
Totally agree; the doors are a big source of noise along with the areas behind the seats and in the rear compartment. Did you do anything to these areas?
“O” we never like to assume things. Generally I have the ez bake in for most drive times, when going on a longer trip or overnight the fiberglass top is in. Noise wise – not a noticeable difference.
