What is the your value of fiberglass insulation?

Insulation is rated according to its R value, or resistance to heat loss: the higher the R-value, the higher the insulating value. Standard fiberglass insulation has an R-value of about 3.5 per inch of thickness; this provides an insulating value of R-11 for 2×4 walls and R-19 for 2×6 walls.

What is the are value of building materials?

In construction, the R-value is the measurement of a material’s capacity to resist heat flow from one side to the other. In simple terms, R-values measure the effectiveness of insulation and a higher number represents more effective insulation. R-values are additive.
