Sound deadening

[That Bronco Guy]

What kind of effect, if any, have these added materials had on interior temperature regulation?

I have not checked any thermal loads before and after, so I could not provide any substantiated data for temperatures. Using “bro science” I would think adding air gaps via foam, thinsulate, and the foil back deadening mat would definitely help with insulation like those shiny foil heat emergency blankets I have in my survival pack I hope I never need . Similar idea behind home construction with the foam and thinsulate.

Sorry I didn’t even think about thermal data. That would be a neat test.

Love it when guys go full nerd on this kind of stuff.

Yeah, I understand what it *should* do, but these things don't always create enough of a difference to make a difference.

Thermal regulation would be my primary interest in these kinds of products, I was curious if anyone has had some results from that perspective to share.

We manufacture insulated headliners for Broncos and Jeeps, so we've done quite a bit of testing on the thermal side. While every vehicle/setup is different, we've found that radiant barrier materials can make a significant difference in reducing heat transfer from the roof. We did a simple before/after test on a Wrangler using the same radiant barrier technology we use in our Bronco headliners and measured a 36°F reduction in temperature after sitting in the sun.

Video:

Not a Bronco-specific test, but the physics behind the radiant barrier is the same, and our Bronco and Jeep headliners utilize the same radiant barrier technology and similar multi-layer construction.

I did multiple stages of Resonix in my Bronco Raptor. All doors done, all door panels; full cargo area, cargo panels, and firewall

Full resonix treatment- butyl rope to tie the door bars to the outer skin, mega cld tiles, guardian - Hydrophobic Melamine & MLV Automotive & Marine Sound Absorbing Pad and Fiber Mat - Self Adhering Automotive Sound Absorber & Decoupler

If the triangle gasket is whistling there in my photos that is your issue most likely. If your door is whistling at the top by your ear then carefully pull down the window gasket on the hard top and even a tiny bit eliminates the whistle. They move down a little.

wow! Did you take apart the dash for the firewall application? Id appreciate any insights into the process, I’m looking to start with the doors, then cargo. Have you done the wheel liners, I’ve heard this can be effective for road noise? I was contemplating upgrading the wheel liners to the aluminum aftermarket first and maybe sound deadening those instead of deadening the plastic.

 

[stevep1590]

well, the sound deadening
definitely had a very noticeable impact. I am happy with the results.

Wow, this is great! Looking forward to the video!

I didn’t even think about the skid plates. Can you elaborate on what you did?

Thanks!

I agree with others here. I’ve done extensive work and trial and error. The kilo mat plus closed cell and 3m thinsulate works amazingly well. I have a video I’m editing on how I did mine. Should be done soon. Did lots of Db testing. Doors are big and so is floor. The headliner is not a big bang for buck but does help absorb sounds once’s in cabin to give a more premium feel. Also believe it or not the largest change of frequencies in the cabin was adding Mat to inside of skid plates. I have full skids and I used neoprene washers. Huge change in road sound. The bronco can be nearly as quiet as a nice suv such as an Audi q7. Just takes a few afternoons and $5-800 in materials. But your sound system will be the big win. I thought about upgrading but now it sounds premium and we found we can’t turn it up as loud anymore ha!

The testing charts I attached are probably a little louder than what you should expect. I have icon uca and those things really transmit the road noise and I’m on portals which don’t add noise but push tires well outside the wheel well so that adds substantial turbulence along sides.

Also as other commented. It’s a brick so above 60 mph you lose the battle to aerodynamics.
