mat in tn Posted February 6, 2023 Share Posted February 6, 2023 I found something for $38.99... https://www.speedwaymotors.com/Aluminized-Heat-and-Noise-Insulation-Shield-Double-Sided,32193.html? Aluminum on both sides, fabric in the center. 46"x75" so it will do the whole firewall. I have some Kilmat sound deadener lying around so I'm going to lay down first. It's butyl rubber so it should stand up to the heat. This is approximately an arm and a leg less money than anything else I've found. when I was in retail many years ago, I learned a valuable if not misleading tip. "Marketing is focused' often what something is depends on what they say it is. for example, one person sells a pint of coffee pot cleaner for 5.99 while the same product is sold on the bottom shelf as cleaning vinegar for 2.99 gal. that is not always the case of course as sometimes there may be something like a flame retardant added to a specialized product. but don't be afraid to do a little "bulk, discount "research. just sayin!

I put in a few years at hardware stores myself, lots of helping customers find cheaper methods of doing things. Some people don't want that though, they want assurance that a product is for their exact application and don't mind spending more. I get that, sometimes I am in the same boat especially when we are talking chemical compatibility and environmental resistance. And yes, many times a product may be largely the same but it comes with extras, like customer service. Sometimes it makes a world of difference. And then there's just scams, like a certain gun lube manufacturer who sells vegetable oil for $15 in a 2oz bottle. In this case I was kicking myself because I knew there was something out there. Building materials is neither my forte or my post as a former Home Depot employee. I did come up on Reflectix, and after some reading on hot rod forums, it does amazing at radiant heat (probably great for camper vans) and terribly at conductive heat and sound insulation. But perhaps there is use for it yet. Some users recommend Peel & Seal which is really cheap, but it's literally just aluminum-backed tar tape. No thanks. Anyway, I ordered the roll I posted above and I'm hoping for the best. I'll use aluminum tape to seal off the edges and keep the water and rodents offa it.

Pictures will follow once I'm finished... I took that firewall insulation material and glued Reflectix to it. Then I cut it to shape and taped the seams with foil tape. I'm going to glue a rubber sheet on top so it looks like the original firewall, and then cut all the holes and stuff. Link to comment Share on other sites More sharing options...

JimJam300 Posted February 11, 2023 Author Share Posted February 11, 2023 Good idea! That's okay about the sound insulation, I'm laying down the butyl Kilmat on the metal and that should help a little. Fabric/foil firewall material cut to shape and Reflectix ready to trace. Two halves ready to glue. Insulation glued together with 3M Super 77 and edges sealed with foil tape Just ordered a roll of 1/16" EPDM to glue over the top and then I'm going to cut all the holes.

JimJam300 Posted March 4, 2023 Author Share Posted March 4, 2023 That looks great! I'll have to copy that for Dad's truck. Well it's finished. If I could do it over again I would use 3M Super 90 instead of 77 and a different rubber material. I chose EPDM because of its weather and chemical resistance, but it's glossy and traps a lot of dust. It is difficult to keep clean when handling. To cut the holes I used a break-off utility knife and 3 blades. They didn't like going through the fabric material so I cleaned it up with some medical shears and it turned out decent. There's still some adhesive residue on the rubber but luckily acetone is safe on this material. The Reflectix doesn't make it as flexible as the factory insulation so I will report on the difficulty of the dash installation Link to comment Share on other sites More sharing options...
