R-Value of Insulation

The proper R-value for 2×4 walls in homes in IECC climate zones 1 and 2, is between R-13 and R-15. Most homeowners choose fiberglass batt insulation for these walls. It is also recommended to insulate the attic, and crawl spaces with the same R-value. Most contractors recommend blown-in cellulose, fiberglass or cellulose fiber-blown-in insulation for these areas.

The type of insulation you choose depends on the moisture content in the building. A higher R-value can help slow outward vapor drive, which is advantageous in cold climates, and allow the walls to dry more readily toward the interior should they become wet. When choosing a higher R-value for your exterior walls, you should consider using kraft-faced fiberglass or foil-faced rigid foam. It is also important to understand the R-value of the ceiling, band and rim joist area when calculating your overall home R-value. You can find R-value tables and calculators online.
