Thermal barrier?

[EddieExpedition]

I’m thinking about building a heat shield of sorts under the rear cargo area on my blazer. Since we have the camper on there, it’s difficult to do much interior insulation so I thought something underneath might help.

Has anyone done this? I have a large sheet of aluminum I can use. Cut it to fit between the frame rails and bolt to the underside supports of the cargo area. Hopefully reflect a bunch of road heat?

Look up lizardskin. They have both a spray on thermal barrier and sound control. Both can be sprayed on the interior (or exterior if you can prep it properly).
