How thick a concrete wall would be needed to give the same insulating value as 3 and a half inches of fiberglass?
Poured concrete has an R value of about 0.08/inch. Fiberglass batt has an R value of about 3.14/inch (blown fiberglass wall insulation is about 3.2/inch). From these values we can calculate that the equivalent insulating thickness of concrete would be about 3.5x3.14/0.08 = 137.4 inches. Note that concrete blocks have a somewhat better insulating value due to the incorporated air pockets. A 4" concrete block has an R value of about 0.2/inch An 8" concrete block has an R value of about 0.15/inch A 12" concrete block has an R value of about 0.1/inch
