Now, before we get rolling, please read this first. I understand that Lizard Skin and other materials are available to help reflect heat. That is not what this is for. It is for adding a heat shield after you have a finished product. The heat from the Produce truck is pretty unbearable in the Oklahoma summer heat. I used the Fat Mat Xtreme and the factory type firewall insulator mat. I thought I was pretty thorough. Anyway you can read about it here. https://www.jalopyjournal.com/forum...p-in-the-produce-truck.1058588/#post-12012475 I found this and was looking into it, but the cost takes me back a bit. I was planning on covering the bottom of the cab with this, but I don't want to refinance my house to do it. https://www.heatshieldproducts.com/inferno-heat-shield With most hot rod stuff, it starts life as an industrial product and then is repurposed and repackaged. Anyone know where this might be purchased in larger quan***ies for less?
http://www.distributioninternational.com/ I've used them for the kind of industrial projects we get into. Yes, then I find out about what I need for my personal projects.
Root, I just finished installing this product, it seems to look and preform like Dynamat at a fraction of the price, I just finished installing it in my old Deuce sedan. HRP https://www.amazon.com/Kilmat-Deadening-Automotive-Insulation-dampening/dp/B0751CBXBT HRP
Danny, that part is done already. The stuff I am interested in is on the bottom of the cab (Outside).
Some good info here :https://www.jalopyjournal.com/forum/threads/under-floor-insulation-case-in-point.662555/
What about coating the exhaust pipes under the cab? Could make a heat shield like on a motercycle to go between the exhaust and the floor? Just spitballin’
What about O.E. undercar exhaust heatshields. I would think they wouldn't be that expensive from a bone yard. It might take several and since it's under the truck who'd care if it isn't pretty? -Dave
You should probably check Summit Racing, I ordered some hot rod heat sleeve heat shielding stuff from them and it was reasonably priced I thought. And it was made by Heat shield products. https://www.summitracing.com/search/brand/heatshield-products
That's what I listed in the original post. The piece I need is about $300. That is about the same size as the bottom of the seat. I have pondered using some aluminum or stainless and make my own. Maybe sandwich some fibergl*** mat between it and the bottom of the floor etc.
That link you posted was for one of the heat shield products items. The link I posted is for all of the heat shield products Summit sells They make and sell many more products through Summit. They also list some muffler wrap/style heat shields on that Summit link. Just trying to give you some options. I’m with you on the price being expensive, the way I understand it there’s some pricey technology involved in these heat barrier products. I think it’s pretty tough to duplicate them or to make something yourself. Your best results might be an industrial insulation product like a ceramic type of insulation. Far better than fibregl*** and we used it all the time on industrial job sites for wrapping high temperature pipe etc. It’s really tough to stop heat transfer through materials. https://www.google.ca/search?client...90.254.3......0....1.........0i71.iRcWOlh6ymI I didn’t look, but by chance is your exhaust system ceramic coated ? That can reduce the running temperature of the system.
A good friend of mine on here got a fire blanket used by California forest fighters. I cut that and laid it over top of 110ml dynamite. I can keep my feet barefoot on the floor (rubber mat, no carpet) in the summer and it’s cool as hell.
This is a really odd deal. The seat base is the fuel tank. On the big truck cabs, they had the fuel tank under the seat. I cut the top out and insulated the inside. I added a tray for the wiring panel. I can open the tray and the heat pours out. See here. https://www.jalopyjournal.com/forum/threads/the-legrange-produce-tribute-truck-build.936696/page-4 There are no mufflers in close proximity. I think it catches the heat from the engine bay as it p***es under the car. @Blue One ,That ceramic blanket might be the ticket. If I could sandwich that between the floor and a sheet of stainless it might help.
This is what's in the sandwich Close proximity to very high heat sources. Inswool available at refractory supply or on line. How they create the sandwich ?? Also, adding more or better insulation under the carpet/floor covering would do the same thing as adding insulation under the floor pan.
Take some sheet metal. Put it between the floor and the exhaust. Make some brackets to hold it off the floor. about an inch if you can. It will do wonders. You may have to put some bead work in it to stiffen it up. A lot of newer cars have similar to this. Some have some insulation material between that and the floor. But just the tin does a lot.
Yep, this, if you can. Even a thin aluminum sheet between the cab firewall and floor spaced far enough away for air to p*** between will do wonders. Think the stuff the OEM puts between a converter and a floor pan. My son stripped out a 2004 Dodge Ram a few months ago. Between the motor and the firewall is a very large piece of material with a shiny surface towards the motor and a cardboard like material on the back side, towards the firewall. The stuff is probably less then 1/4" thick and is held to the cab with a few clips. I suspect that one piece from the Ram will cover more then 1/2 of your firewall and floor. Should be able to get it pretty cheap from a pull a part, look for a truck with the motor & trans already out. Gene
This embossed aluminum sheeting is available and similar to that used by auto manufacturers for under body shielding of exhaust system components, mufflers etc. Easy bent or cut to shape and available readily through auto stores down here. Put a nut-sert in sheet metal etc and drill a hole, use a metal thread screw and large flat washer to keep sheeting off surface and maintain a consistent air gap?
I certainly wouldn’t be keeping my bare feet on it!!![emoji3][emoji3] Sent from my iPhone using H.A.M.B.
So, I wonder if I sandwich this between a piece of .032" aluminum or stainless, if the air gap would be sufficient? I could take the rest of the roll and put it under the carpet. http://www.ceramaterials.com/ceramicfiberpaper.html
You could experiment with just a little disposable foil roasting pan from the grocery store. Do you have a temperature sensor gun? You can get one cheap on Amazon if not. Have you played around with Reflectix at all? They have a product that's just a perforated mylar film (no bubble wrap) that I use around the house. https://www.reflectixinc.com/
Have you looked at the offerings from DEI yet? I used their insulation along with a shield for the firewall and trans hump that was further up into the cab in my truck, (along with some of their wire sleeves for some stuff that was in close proximity to a header) and was pleased with the result and reasonably pleased with the price. they have other sections from whats in this link, but just to get the idea http://designengineering.com/products/shields-reflectors/
So are yours. The price you listed is for a smaller piece. It has a pull down window for the other sizes. Unless, I found a different vendor on ebay?
