How Insulation Saves You Money
Insulation slows the transfer of heat — keeping your home warmer in winter and cooler in summer. According to the DOE, adding insulation to an under-insulated home is one of the highest-ROI home improvements available, with payback periods of 1–5 years.
Where to Insulate First
- Attic: Heat rises, so attic insulation is the #1 priority. Target R-38 to R-60 depending on climate.
- Walls: Exterior wall insulation reduces both heating and cooling loads significantly.
- Basement/crawlspace: Insulating below the living space prevents cold floors and moisture issues.
- Air sealing: Sealing gaps and cracks can be as impactful as adding insulation.
Federal Tax Credits
Under the Inflation Reduction Act, you may qualify for a 30% tax credit (up to $1,200/year) for insulation and air sealing improvements. Check with a tax professional for eligibility.
