Do any of the Dynomat or Dynaliner products actually quote a U-factor? If so I would take a look at those and compare to the Thermo Tec product.

Something I did also was run insulation across the top of the foot boxes inside the cockpit since they are exposed to the hot cockpit. I would be inclined to go the 1/4 stuff on all the floors or at least under the seats, possibly the end and top of the foot boxes, and use the 1/8 stuff everywhere else. The 1/2" stuff sounds really thick and will probably pose issues getting the seats bolted down and fitting the carpets. ERA cautions against using too thick of insulation to avoid problems fitting the carpets and getting them to lie flat and smooth. I didn't really have any trouble with all I put under the carpet but it probably is a caution to be aware of.

In general to the ERA community, has anyone used an insulation as thick as 1/2" on their floors?
