Insulation recommendation, Greiner HVAC, CAInsulation is one of the most cost effective ways to improve your home’s overall comfort and efficiency. It creates a thermal barrier which prevents stifling heat from entering in the summer and indoor heat from escaping in the winter. For a home that is comfortable and efficient year-round, make sure your home is properly insulated.

Quick Facts about Insulation

  • In California homes, heating and cooling accounts for 31% of energy usage

  • Proper insulation can lower your heating and cooling bills by 10% to 20%

  • Insulation can pay for itself in just 2 to 3 years

Recommended Insulation Levels

Insulation effectiveness is measured in R-value. The higher the R-value of insulation, the more effective it is. Certains areas of the home need more insulation than others.

*These recommendations are based on climate zone 3

  1. Attic: R30–R60

  2. 2x4 Walls: R13–R15
    2x6 Walls: R19–R21

  3. Floors: R19–R25

  4. Basement Walls: R11–R15

What Proper Insulation Looks Like

Insulation in the attic shouldn’t just come to the top of the joist; it should completely cover the joists.

R15–R21: Add more insulation

R38–R49: Probably enough insulation
