A common differentiating criteria between different types of insulation is the amount of R-value they provide when correctly installed. Where using a simulated energy performance analysis sections of ducts that are.

The second R-value for mass walls applies when more than half the insulation is on the interior of the mass wall.

R-values for walls represent the sum of cavity insulation plus insulated sheathing if any. While there are additional considerationssuch as venting and moisture problemsto take into account when you insulate under floors the United States Department of Energy recommends an R-25 rating in cold climates and an R-11 in warmer parts of the. Different materials resist heat conduction differently and that is what R-value denotes.

Kraft-Faced Batts Rolls. The insulation for basement walls must be from the top of the wall down 10 feet below grade or to the basement floor whichever is less.
