Why Insulation Matters

Insulation creates a barrier around your home to protect it from the outside elements, making insulation essential for maintaining a comfortable and energy efficient home. By blocking heat transfer, controlling moisture levels, and reducing air leakage, insulation helps regulate indoor temperatures, lower energy bills, and create a healthier living environment. Insulation upgrades—especially when combined with air sealing—can solve numerous issues in you  home, such as:

  • Ice dams
  • Drafty rooms & cold spots
  • High energy bills
  • Poor heating & cooling performance
  • Moisture & mold problems

Get Started with an Energy Audit 

The best way to know exactly where your home could benefit from insulation and air sealing upgrades is with a comprehensive energy audit. At Green Team LI, we start every project with an audit because it provides an in-depth analysis of your home’s performance and gives our team valuable insight into where improvements need to be made. 

During an energy audit, we use a whole-home approach to pinpoint inefficiencies and determine what home upgrades will have the greatest impact on your comfort, energy usage, and home health. Afterward, we’ll provide you with a detailed report of our findings, service recommendations, and guidance on eligible rebates and tax credits
