Best Bed Liner for Heat Reduction

[77broncodriver]

Hey Everyone,

Ive been searching all day and I haven't found the answer ive been looking for.
Im stuck, Im trying to redo my interior. Right now I have the POs diy liner that is pealing off in big chunks and also I have a hot air coming in from the new holes for the shifters.

On top of that my floor gets so hot especially the passenger side where the header is so close it burns the hair off your legs!

I use the bronco as hopefully daily driver again if it still behaves the rest of the summer, but also go as often as i can to the trials and am pretty messy in general so i dont think carpet will hold up to my needs.

I thought about LineX but is it really worth it? I want my floors to be cool and does linex do good with reducing heat?

I also saw the al's hnr in bronco driver and thought of that but I dont like the look of the als liner to go on top from the pics.

I like the idea of raptor liner but will it help with the heat?

The best way to me is hnr, dynomat, then carpet but im affraid the dirt will destroy it. I work constuction and at a ranch over weekends and get concrete and a lot of stuff all over the place.

Sorry for the long story but now working over summer I really want to get the interior more comfortable.

Thank you, Evan

I have linex in mine and just like you, I don't want to have anything inside either. The liner itself does not cut enough heat from my headers, and on the passenger side where the header is it's starting to bubble a tiny bit.

I've look extensively into heat shielding, and I'm currently about to install some of the DEI aluminum shielding that sticks to the underside. I'm also going to wrap parts of my exhaust. I really wanted to avoid these measures because I don't want anything holding dirt and moisture under there, but I'm left with little choice.

There was some sort of aluminized shield mated to a substance called Poron, but it was really expensive. Apparently, Poron is some sort of temp resistant urethane, so water retention wouldn't be an issue as it might be with aluminized fiberglass cloth (DEI).

Bed liner is not a good heat shield. I have seen it bubble up from exhaust heat getting to it. Get it hot enough and it will catch fire.

Have you guys heard of the roofing material that is like dynomat? What if I put it on the underside under the front seats then DIY spray on liner the inside?

Look into Lizard Skin. They have both a heat and sound deadening spray in product.
You could probably top coat their product with a professional spray in liner.

What about a heavy duty version of dyna-mat that can be applied to the underside of the floor pans?
Seems like if we stop the heat before it gets to the floor pans it would be better.
I have this same issue and am still trying to decide what to do.

Most of that stuff can't take heat. Apply heat to dynamat and it turns into a gooy mess.

I have Rhino lining on both the underside of the Bronco (stops at top of floor pan and firewall) and the entire interior. No carpet. It does not help with heat. Trans tunnel and floor pans get quite warm.

 

[77broncodriver]

Well then linex and rhino liner are out of the picture, best bet is dynomat like stick on underside and then rapper liner on the inside. Anything wrong with that?

 

[HoosierDaddy]

Man , I wouldn't stick anything like dynomat near my exhaust , nothing quite like catching tar on fire .... just saying.
It'll get soft and eventually drip onto the exhaust.
Not a good idea in my opinion.
See post #7 above ....

ah didnt read that all the way. there has to be some better way than carpet right? I just drove a couple hours with the top off at night and I was still sweating inside there is so much heat coming from my floor

Mine gets really hot in the back with a 2 inch body lift , the guys at the muffler shop pushed everything up high. So hot that trash bags melt . Thinking about getting a piece of sheet metal and mounting it underneath on standoffs

 

[77broncodriver]

That's a good idea, I might need to get my exhaust redone first, the last exhaust shop I went to made the muffler touch the body, I didn't notice till recently, but I can try putting a couple pieces up by the headers I guess

The factory muffler shields aren't pretty but do a good job of keeping heat off the floor. They are really pretty simply made and are easy to replicate. Also, after I installed the A/C, I could feel a lot of heat coming in through the firewall. You would be surprised at the amount of leakage you can have there. Do whatever you have to to seal it up. I used body plugs for the big holes and RTV for the small ones. I put a drop light in the engine bay and stuck my head under the dash to find the leaks. I also doubled up the firewall insulation pad and floor insulation under the vinyl floor. The stuff supplied with carpet kits just isn't thick enough. Thermal barrier mat needs to be used under the carpet insulation in areas where headers run, otherwise the pad will get scorched and stink up the car's interior.

That's exactly what I had in mind if I have heat issues also.

with enough time and thought put into it , you could probably get a vendor to bring that to market if it could be done properly.
There are A LOT of complaints about the radiant heat in these things.

I am gathering up some SS and when I change my transmission, I am going to install shields. Not sure I can get it under the tunnel with the transmission in.

 

[Arikilen]

A shield there would be a huge difference!

The brace under the passenger side would make a sweet place to put in the shield. I think I would make a shield from a piece of steel similar to one of the floorboard replacement sections and attach it to that brace. This would act like dual pane glass and provide some insulation. If you wanted to go one step further, might put some insulation or some sort of fresh air ducting to it from the wheelwell.

I think I may lay under my Bronco tomorrow and dream about it.

 

[77broncodriver]

These are some good ideas, when I redo my center console and transmission tunnel cover I'll put 2 layers with a couple inch gap or so

I added the microsheres to my primer inside and underneath. 2 coats. I'll also be running Al's as that's what Nick's runs on his restorations. It's all-in-one heat and sound versus lizard which is 2 different applications. on the firewall I'll run the factory insulation. If it still gets hot after that, I'll run a heat shield over the muffler.
