After about 30 minutes of driving, the inside of my car gets hot like heck due to exhaust system (headers/dual exhaust pipes) radiant heat transfer through the floor pan and transmission tunnel - to the point where my wife doesn't enjoy riding in the car. I put 1/2-inch thick, adhesive-backed closed-cell foam rubber insulation sheets on the inside of the firewall (under the dash) and it does a good job there of preventing heat transfer from the engine compartment. I may consider putting a thinner 3/8" or 1/4" closed-cell foam rubber insulation under the carpet, front and back.
What can I do on the underside of the car to reduce heat transfer through the floor pan? I'm considering adhesive, foil-backed thermal barrier sheets from Home Depot on the inside of the transmission tunnel and underside of the floor pan above the dual exhaust pipes and mufflers. I'd like to hear what others are using as a cost-effective barrier to reduce heat transfer through the floor. And what about those 1/2" tall exhaust pipe shield standoff mounts that clamp to your pipes using standard stainless steel hose clamps - are aluminum exhaust shields standing 1/2" above your exhaust pipes (like modern cars) more effecting in dissipating exhaust heat and preventing floor plan heating than reflective foil backed sheets adhering to the underside of the floor pan? Let the discussion begin - thanks FABO Nation.
