The R-value of concrete is relatively low, typically around 0.08 to 0.10 per inch of thickness. For 120 mm (approximately 4.7 inches) of concrete, the R-value would be around 0.38 to 0.47. This indicates that while concrete provides some insulation, it is not highly effective compared to materials specifically designed for thermal insulation.

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

Does concrete have an R value. 8 inches is equal to about a single pane of glass. Not much at all...?
Yes. Don't know for sure but its pretty low. however note that R value depends on the thickness. You double the thickness you double the R value.
What is the R value of concrete?
The R value of a material is the thermal resistance of the material, so is dependent on the material's thickness. R is also the inverse of a material's thermal conductivity U. To work it out you need the k value ( the thermal conductivity) of the material and the thickness, then R=thickness/k. The k value for structural concrete (of density 2300kg/m3) is 1.6 W/mK (Units: Watts / (metre x degrees Kelvin) so for a thickness 100mm (0.1m) of this concrete, R=0.06 m2°C/W. Note that the R value in imperial units will not be the same. Check the units for any R value of any material that is given.
