I want to say either R-Value or Temperature Value? Probably R-Value... Out of answers: a. convection value b. R-value c. temperature value d. solar value
No. A higher R-value is a better insulator.
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

y=a(1-r)^t where a is the initial value, r is the rate as a decimal and t is the time in years.
The U value is the inverse of the R value. For R value 19 insulation the U value is 1/19, or 0.0526.
