right now my K10 has no carpet, just bare metal. the floor gets very hot.

rhino liner seems like a nice choice, but it don't like the texture, because it is hard to clean

i was thinking about using some of that Dyanmat sound barrier/heat shield stuff and then throwing a one piece floor mat on to of the dynamat:

heres alinkto the dynamat:

iam also going to use the dynamat on the frirewall from the inside of the cab, hoping to keep firewall heat out of the cab.

what kind of solutions have any of you guys come up with?

do you think i can get rhino liner done with a smooth finish, rather than a the standard textured finish?
 
Just did this in my truck. a layer of EVA sound deadener then foil backed jute padding ($70 each, ordered from LMC) topped with the stock rubber mat. Kits come pre cut and runs all the way up the fire wall. Huge differance! P/O just the laid rubber mat on top of the steel floor, couldn't here myself think and my a/c couldn't compete all the the heat. Also lined the inside of the doors which helps alot.
 
Rhino Liner and dirt.

If I had to do it over again, and still might one day, I'd put on MORE Rhino Liner. Then later the dirt.
It's better than bare floor but not as quiet as I had hoped it would make it. Still gets warm and only sorta quiets the interior down. Then again I have like a 1/8" coating of Rhino Liner instead of 1/4" like most pickup beds get and even that wouldn't help as much as that thick factory insulation. Then again this doesn't retain moisture like that does.

When Blaze was our vendor here he had a spray on insulation kit and said the thing to do was spray that on then spray on the bedliner he sold over top of it. That sounds like a great idea to me...but I can't really go back now.

Thought for you but Rhino Liner can be sprayed to a smooth(ish) texture. I've seen an entire Tahoe "painted" with it. Looked more like thick paint with orange peel texture rather than the standard Rhino Liner texture. A good Rhino Liner sprayer should know how to do this.
 
Like AJM said, Rhino Linings can be sprayed smooth. I use to own a franchise and the texture is the final step.

2 coats of Hurculiner - do it yourself

after this - lay down the "quick roof" roofing material stuff ( Home Depot) instead of Dyanmat. Dyanmat is a waste of money IMO

After this - carpet with padding underneth .
 
I'm looking into lizard skin. It comes in a heat shield coating and a sound barrier coating that you can put on top of each other, plus you can sand it smooth.

can you post me a link to this product?


so after work today, i got some more time in on my inner firewall.

i got all the ventilation equipment out, and started removing as much of the factory insulation as possible.

tomorrow i will remove the steering column, pedals, and fuse panel to remove the rest of the insulation.

i'm still debating on what to insulate the firewall with. i have a fresh roll of this dynamat thats supposed to block noise, i just don't know how well it will insulate the cab from engine heat.

i want to finish the firewall and get the dash back in, and i will figure out what to do about the floor later.

do you guy's have anything to recommend that would insulate firewall heat better than the dynamat?

No rubber product is going to insulate from heat.... I don't care if its Herculiner, Lizard Skin or Rhinoliner or something else.

The material will need to have a ceramic component to actually reflect heat away from the interior. I had very good luck with products from ThermoTec and had some sheets of their material under my old carpet in the Burb. It really helped to control the transmission tunnel heat well. Summit sells the complete line of ThermoTec products if you want to do some more research on them.

Lizardskin ceramic insulation, sounds ceramic to me. Check out the website and read a little on it.
 
My bad, I'm posting from my phone. The rest of that last post was check it out and see what you think. It says there are ceramic particles in it but what does that really mean?
 
Your right. Ceramic is what you want...but most undercoatings don't have ceramic in them. I know Lizardskin has a version with ceramic, and that's the one I'd use for my own build.

Of course it would also make sense to treat the heat at the source (exhaust) so getting headers ceramic coated or at least shielded with ThermoTec products would keep the heat from ever reaching the floorboards in the first place.

I put the dynamat on my firewall and it only mildly helps with heat. I put it on the underside of the trans tunnel and that works better. It works great for noise, but not for heat blocking.

What about shielding from heat AND cold? It gets to the high 90's here in the summer and -10 or lower in the winter. Would it be possible to lay down insulation then spray over it with a waterproof liner? The truck sees a considerable amount of deep watercrossings,water,dirt,mud,snow,etc... and any sort of padding or carpet would be destroyed in a hurry.

I'd like something that can help in ranges from around 120° down to -40°.
 
I guess I'm the only one here to have used bubble wrap!..

I got a large roll free where I picked up pallets for firewooid,and when I had my carpets and seat out of my 79 Bonanza C-10 I had then to repair a few rusted floor areas,I decided to put that in under the carpet...it made a huge difference in the warmth of the cab in winter,and seemed to help keep it cooler in summer...I would have prefered ising the aluminum type of bubble insulation,but my frugal soul just could not see spending money for any when I had 100+ foot roll of bubble wrap for free at my disposal...I didn't keep the truck that long after I put it in,maybe a year or so,so I dont know if that encouraged rusting or not...

I've also used some thick black rubber type "mat" under my carpets I found in the same place as the bubble wrap,I think its used under heavy machines when they are shipped..I also used some closed cell foam on a roll too,that worked great under the rug in my cargo area...
 
thanks for the replies fellas. i think i am gonna go with that Lizard Skin product. I've heard good results about that stuff here and on another forum.

After that, i will insulate my exhaust pipes up with a roll or 2 of that exhaust wrap to keep the floor board temps cooled down. The exhaust pipes run directly under my feet and are awefully close to the transmission. i can't imagine that could be helping the transmission out very much.:doah:
