Most of you are probably aware of Reflectix and other types of radiant barrier material used for blocking radiant heat. It's used in windshield shades, attics, etc. Well, I have started lining the inside of my cab and sleeper roof with this material. The idea is to make the air conditioner not have to work as hard to keep me cool because there is less radiant heat penetrating the cab and sleeper to begin with. In addition to giving the inside of my truck a NASA-ish feel, I am certain that it will make the truck cooler. It should also make the truck easier to heat in the winter because it will prevent heat loss from the truck as well. I am going to cut out pieces of the stuff fitted for my side windows, which should work well as a heat and light blocker.
Don't worry, the material doesn't have to be facing the source of heat. In radiant decking used in roofing, the reflective side is facing down (the shingles are on top) and the attic temperatures are something like 40 or 50 degrees cooler than without the barrier.
The material also muffles noise, which is an added benefit.
The rolls of the stuff cost about $20 to $40 at Home Depot depending upon size. This approach is a one-time project that should keep you cooler in the summer and warmer in the winter.
