Shopping for Insulation is Easy
Identify your Project or R-Value
The insulation aisle is organized by project area and R-Value for your convenience. Use our insulation recommendations chart to determine what R-Value is best for your project.
Blown-In insulation is installed using blowing machines; best for adding additional insulation in attic.
Continuous rolls are easy to transport and can be cut to length; great for large areas.
Batts come in pre-cut lengths for faster installation and each package contains more square feet than rolls; ideal for framed cavities.
Faced insulation uses kraft paper vapor barriers to control moisture transmission between walls and floors.
Unfaced insulation does not have a vapor barrier; can be used over existing insulation in the attic, or where moisture control is not needed.
All purpose insulation combining the benefits of improved air quality, fire resistance, sound absorption and outstanding thermal performance.
Check your local building code for vapor barrier requirements.
The Department of Energy recommends different insulation levels based on regional climate zones to increase energy efficiency.
Below are the U.S. Department of Energy recommended minimum R-values for your climate zone.
Your Climate Zone: 4
|Attics||2x4 Walls||2x6 Walls||Floors||Crawlspaces|
|Zone||4||R38 to R60||R13 to R15||R19 to R21||R25 to R30||R25 to R30|
