And the Department of Energys corresponding climate zone. Polyisocyanurate features an R-value up to 80 which other insulating materials cannot touch. The R-value your insulation needs depends on your local climate.

126 R-value per Inch. 27 R-value per inch. R value thickness mThermal Conductivity WmK Unlike thermal conductivity thermal resistance R-values solely depend on the materials thickness.

37 rows What R-Value For Attic Insulation. An insulating materials resistance to conductive heat flow is measured or rated in terms of its thermal resistance or R-value -- the higher the R-value the greater the insulating effectiveness. R-value figure can be calculated from the equation.

Spray foam insulation especially the closed-cell kind has an R-value of 60 per inch sometimes as high as 65. Backer -- 182 Vinyl Siding --. Compare that to fiberglass insulation including loose-fill blankets or batts.

As you can see above each of the materials represented has different R-Values. Insulation or other Building Material 9. 10 R21 Existing Poor.
