I have my back seat out and wondering which Dynamat I should use for sound and heat barrier. I'm only doing the area under the back seat. I was looking at their website and they show a bunch of different ones. What are people using just under the back seat? How about Fatmat?
They are all pretty much the same the only difference I've noticed which is really a larger factor some can weigh up to 2kg a sheet so for me that's what I'd look for just my option
According to their website, Dynapad for noise control and Dynaliner for heat. Dynapad comes in 3/8 inch thickness while Dynapad comes in three thicknisses. The say putting down a layer of Dynamat first doubles the effect.
Here is their web site. https://www.dynamat.com/products/dynaliner/?tab=automotive
I am restoring my '74 SE. Used Dynamat everywhere then added pad or liner as appropriate. I even added a layer of Dynaliner to the trunk/passenger compartment divider.
Don't be fooled. Any thickness of rubber/foil transfers heat very well. To reduce heat look for thermal blocking sheets. I tested my naked interior with just a dash and drivers seat for about a year. I mapped hot spots with a laser pointer temp. gun and blocked hot spots around the hump/firewall and center section.
Testing showed about 15 degrees blocking for a single layer of what kinda looks like fiberglass mat about 1/8th inch thick. Not wanting to add 75LBs to my car I used foil backed adhesive rubber roofing tape about 6 inches wide here and there to deaden sound on floors and package tray. Carpet has worked for 80 years and it made the biggest impact, I ordered extra and carpeted my package tray.
After adding Classic Auto Air's A/C system the car is a joy to use even in 99 degree FL. weather. :2thumbs:

Your carpet came from a 1942 year model car?
