R-value of foam insulation

Here is how we can calculate the R-value of this wall from the known k-value: R-Value (Brick Wall) = 1 / k-Value = 1 / 10 = 0.1. That means that such a brick wall has an R-value of R-0.1 (this is for a 1-inch brick wall). If we have a 10-inch thick brick wall, the insulation R-value would be R-1.
