The R-Worth ranking of insulation is the thermal “resistance” in the insulating substance to heat transfer. The “R” in R-Value is referring to resistance, and it’s all about heat. When it’s a very hot summer working day, that you are depending on the insulation to maintain the recent air outdoors.
using the R-Price typical to guage efficiency will not be correct. Naturally a thin sheet of foil has no R-Worth, but the chance to replicate the warmth either back again into your house or far from your house will be the important problem.
