Heat/Sound insulation recommendations

[jckkys]

A small search resulted in a long list with no clear winner. It would seem different types would work best in different parts of our trucks. So what works best in the hood may not be the best on the floor. Also I think the doors should get something water proof. I'm also looking at Lizard Skin.

A Bronco did not come with any of that stuff OEM stock.

If it did not come OEM stock you don't need it, isn't that what you are always telling people?

I put a layer of hushmat and a layer of foil duct insulation about a 1/4" thick and then the headliner in my roof. It is rock solid, quiet and cuts the heat.

I put hushmat in my door panels and they are rock solid. No more hollow sound when the door closes.

I put a layer of hushmat and then the Dennis Carpenter vinyl mat in my front floorboard. I will probably put another layer of the hushmat in to hopefully help a bit more with the heat. It helps, but I still feel a good bit of heat and I still have more hushmat.

I have dynamat, racket jacket from wild
Horses, firewall insulation, and a custom carpet kit.

It is very quiet inside, I can talk hands free no issues, and it stays cool. Hard too sounds and feels solid. I put batting from a quilt in the quarter panels. Deadened a lot of sound.

This really is pretty funny... ;D


As a guy who literally only has the windshield frame and glass left stock... lol

I used lizard skin on my 77 and it has a fiberglass tub. What a difference from no coating to coated. I put it on the underneath and I used spray on bed liner on the interior floor. I can drive it with bare feet and no burn. I have long tube headers also.

Noico 80 mm butyl with foil (basically Dynamat), covered with Noico 170mm green closed cell foam (basically Dynaliner) on every surface inside tub, including inner door skin and door panel. Tom's Bronco Firewall insulation on top of that, then carpet. Ceiling will get the 80mm and 150 mm red with and ABS headliner. Stainless steel 18 gauge shield over muffler.

Windows (including windshield) will get Wincos clear film.

Are you refering to inssulating coatings or stick ons?
Certainly there's a place for both, but unless you really need a spray on for your application, I'd avoid it. I can't think of a mod that can reduce your value than a spray-on liner. It should be considered permanent.
Sound deadening isn't so much about blocking sound. It's more about stopping the sound waves from bouncing around the cab. Look at how sound deadening is done in a gymnasium. Sound absorbing panels do the job. Every inch doesn't need to be covered.
I used the 3/8" foam panels from Home Depot behind the head liner, side panels and door cards. Quick, cheap, and unnoticeable.

I just finished this recently. I used KilMat of Amazon. First link has the info. After KilMat I put down some carpet insulation and then vinyl flooring. Then I did the same with my hardtop, KilMat, insulation, then headliner. My Bronco is super quiet and is pretty warm once the heater warms up (I upgrade the motor and cage on heater as well)

Links show what I did. The vinyl floor link is another members project, but I posted near the end of if with my results.

Use Second Skin Spectrum like I did on mine. Made in the USA. They used to be in Rita Ranch but not seeing them there anymore.

Second Skin was only about a mile from the shop south of Tucson doing my frame off. When I went to that location I found they moved to Chicago. Actually they went to Libertyville the suburb north of Chicago where I bought my new '77, at Sessler Ford. This is going increase my shipping costs, if I use their products. The shop has nothing but good things to say about the products. I'm also somewhat hesitant to spray anything on the virtually new body and paint. The lizard skin may be an exception.

I used a 4 gallon kit of lizard skin. Was able to to do both sides of firewall, tub floor and rear wheel wells with sound barrier. I used the heat barrier up front on firewall, floor pans and seat area, again applied on both sides. My interior was then covered in rhino liner. Worked really well. I also wrapped my long tube headers to cut down on heat. My floors stay a few degrees warmer than ambient.

 

[Mikesimp70]

I used Lizard skin heat and sound, topcoated with Raptor inside tub, Tom’s deluxe carpet and firewall insulator kit. Used dynamat in the doors and rear quarters. Rhino on the bottom and in the wheel wells. Nothing in the hood... but now I am curious.
