YOUR ATTIC LOSES MORE ENERGY THAN ANYWHERE ELSE IN YOUR HOME
In a Gwinnett County summer, attic temperatures regularly hit 140–160°F. Without proper insulation, that heat radiates straight into your living space, forcing your AC to work overtime. In winter, the same attic lets heated air escape through the ceiling. Attic insulation upgrades in Georgia’s Climate Zone 3A can reduce heating and cooling costs by 15–45%.
Most homes built before 2000 in Lawrenceville, Duluth, and Buford have attic insulation at R-11 to R-19 from original construction. Georgia’s current recommendation is R-38 minimum, and ENERGY STAR pushes for R-49 to qualify for utility rebates. That gap shows up on every energy bill.
📏 Quick Way to Check Your Attic
Get a ruler and stick it into your attic insulation. Less than 11 inches of blown-in material likely means you’re below R-38. Less than 7 inches puts you below R-19. We’ll measure for you during the free estimate — no pressure, no obligation.
R-38
DOE Minimum for Gwinnett County. Most older homes fall short of this.
R-49
ENERGY STAR Target. Required for Georgia Power $250 rebate and federal tax credit up to $1,200.
ATTIC INSULATION OPTIONS FOR GWINNETT COUNTY HOMES
The right product depends on your attic type, your goals, and your budget. We install all three and will tell you honestly which one makes the most sense for your home.
💨 Blown-In Insulation — Best Value for Existing Attics
The fastest, most cost-effective way to bring an under-insulated Gwinnett County attic up to R-38 or R-49. Blown-in cellulose or fiberglass distributes evenly, fills every gap, and works directly on top of existing insulation — no demolition required. Most jobs complete in a single day.

🌿 Open Cell Spray Foam — Best for Roof Deck & Conditioned Attics
When you want to turn your attic into conditioned space or insulate the underside of the roof deck, open cell spray foam is the answer. At R-3.8 per inch, it creates a seamless air seal at the roofline. The premium option for new construction and whole-home performance upgrades.

🧱 Fiberglass Batts — New Construction Attic Floors
For new construction where the attic floor is accessible and framing is standard, R-30 or R-38 fiberglass batts between the joists are code-compliant and budget-friendly. Best for builders and additions where blown-in setup isn’t cost-effective for smaller areas.
