Yes I believe the heat loss figures put out by TC are accurate. We use about 1/2 inch on the crown of the EZtherm furnace and considering it in other locations as well. You have to be careful though where you put it as it max's out at about 1800 deg. F. so you do not want to put it in any area that gets to that temperature, directly on furnace crowns, etc. We now use it as the last layer of our crown. It is my belief that in some situations the energy savings $$$$$ will more than pay for the upfront cost. It is fragile to the degree that one should handle it carefully. It is the type of material that does not bend easily although it will somewhat. It is best used in flat crown or wall situations. The space saving from standard fiber is terrific.
