The best AC system in the world (and we like to think ours are pretty darn good) can’t cool the whole world. The better the passenger compartment is sealed off, the easier it is to keep it cool. The most common passenger compartment issues leading to poor AC performance are cracked and weathered seals on the doors and windows and no or poor insulation in the firewall and floorboards.
Because our primary insulation objective was keeping the cool in, we laid Dynaliner on every surface we could find. Dynamat manufactures Dynaliner in 1/8”, 1/4”, and 1/2″ thicknesses which are applied on locations where heat loads are highest. We applied the 1/2” Dynaliner to the firewall and the roof, the 1/4” material for the floorboard and quarter panels, and 1/8” insulation to the door panels.
We covered just about every square inch of the interior with both Dynamat and Dynaliner. You can hear and feel an amazing difference…the sound and firmness of the body panels is noticeable when just tapping on the roof and shutting the doors!
We can’t wait to test it all in the Death Valley Challenge. Stay tuned.
