Insulation Types

  • Blown-In

    Blown-In insulation is installed using blowing machines; best for adding additional insulation in attic.

  • Rolls

    Continuous rolls are easy to transport and can be cut to length; great for large areas.

  • Batts

    Batts come in pre-cut lengths for faster installation and each package contains more square feet than rolls; ideal for framed cavities.

  • Faced

    Faced insulation uses kraft paper vapor barriers to control moisture transmission between walls and floors.

  • Unfaced

    Unfaced insulation does not have a vapor barrier; can be used over existing insulation in the attic, or where moisture control is not needed.

  • High–Performance

    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.
