How thick a concrete wall would be needed to give the same insulating value as 3 and a half inches of fiberglass?

To provide the same insulation value as 3.5 inches of fiberglass, a concrete wall would need to be approximately 15-18 inches thick. Concrete is a poor insulator compared to fiberglass, so a much thicker wall is needed to achieve similar insulation properties. Alternatively, adding insulation material within the concrete wall can help improve its insulating capabilities.

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.
