WebFiberglass (Batts): R-2.9 to R3.8; Fiberglass (Loose-Fill): R-2.2 to R-2.9; How Much of the Highest R-Value Insulation Do I Need? Now at a glance, the insulation ratings above could be a little confusing, so keep in mind those are the per inch R-Values. The amount of insulation you need is determined by the climate zone you live in. A colder ... WebInsulation Fundamentals: R-Value Insulation is measured in R-value, the capacity of an insulating material to resist heat flow. The higher the R-value, the greater the insulating power. When you’re purchasing insulation, buy or specify R-value, not inches, as R-values of materials vary. maurices billings mt hours
