WHY GWINNETT COUNTY HOMES NEED SPRAY FOAM
If you’ve lived in Gwinnett County for more than one summer, you already know the problem. It’s not just hot — it’s hot and humid, and that combination is the enemy of a well-insulated home. Georgia sits in Climate Zone 3A, which the Department of Energy classifies as a “moist” zone. That means your insulation isn’t just fighting heat — it’s fighting moisture that seeps into walls, attics, and crawlspaces every single day from May through September.
Traditional fiberglass batts do a decent job blocking heat, but they don’t stop air movement or moisture. Spray foam does both. It expands to fill every crack and gap in your walls, attic, and floor cavities, creating a continuous air barrier that fiberglass simply can’t match. That’s why so many Gwinnett homeowners who switch to spray foam see immediate drops in their monthly Georgia Power or Jackson EMC bills.
📍 Local Fact — Gwinnett County, GA
The average monthly electric bill in Gwinnett County is $155 per month — and that number climbs significantly in July and August when your AC is running nonstop. Proper spray foam insulation is one of the most effective ways to bring that number down year after year, not just once.
Gwinnett County is also one of the fastest-growing counties in the United States, with over one million residents and new homes going up all the time in communities like Dacula, Sugar Hill, Suwanee, Buford, and right here in Lawrenceville. Whether you’re building new or upgrading an existing home, spray foam is one of the best long-term investments you can make in this market — especially as home values across the county continue to rise.
Georgia’s humidity is also rough on older homes. If your house was built before 2010, there’s a very good chance it was insulated with fiberglass batts that have since sagged, compressed, or absorbed moisture. Wet insulation doesn’t work. It loses R-value, promotes mold growth, and makes your HVAC work twice as hard. Spray foam doesn’t absorb moisture — it repels it.

OPEN CELL VS. CLOSED CELL SPRAY FOAM
Both types of spray foam are dramatically better than fiberglass, but they serve different purposes. Here’s how to think about it for your Georgia home:
🌬️ Open Cell Spray Foam — R-3.5 to R-3.8 per inch
Softer, sponge-like texture that expands up to 100x its size
Excellent for interior walls, attics, and vaulted ceilings
Superior sound dampening — great for rooms near busy roads like SR-316 or I-85
More budget-friendly option for large coverage areas
Seals air movement while remaining vapor-permeable
Ideal for new construction framing in Gwinnett subdivisions
Badge:
Most Budget-Friendly
🛡️ Closed Cell Spray Foam — R-6 to R-7 per inch
Dense, rigid structure — acts as both insulation and vapor barrier
Highest R-value per inch of any insulation product available
Critical for crawlspaces, basements, and exterior walls in Georgia’s humid climate
Adds structural strength to walls and roof decks
Completely waterproof — won’t absorb moisture or support mold growth
Best choice for metal buildings, garages, and commercial properties
Badge:
Best for Georgia Humidity
💡 Not Sure Which One You Need?
Honestly, most Gwinnett County homes benefit from a combination of both—closed cell in the crawlspace and exterior walls where moisture is the main threat and open cell in interior walls and attic spaces. We’ll walk you through exactly what makes sense for your home during your free estimate. No jargon, no pressure.

SPRAY FOAM FAQ — LAWRENCEVILLE & GWINNETT COUNTY
At Eco Spray Foam LLC, projects start at $1,800. The final cost depends on the square footage, the type of foam (open or closed cell), and the area being insulated — attic, walls, crawlspace, etc. Every estimate is completely free and comes with no obligation. We’d rather give you an honest number upfront than surprise you later.
Open cell foam is softer, more affordable, and great for interior walls, attics, and sound control. It’s vapor-permeable, which is fine for many interior applications. Closed cell foam is denser, achieves a much higher R-value (around R-6 per inch), and acts as a vapor barrier — making it the right choice for crawlspaces, exterior walls, and anywhere moisture in Georgia’s climate is a concern. In many Gwinnett homes, we use a combination of both.
Absolutely — and Georgia’s climate is actually one of the best arguments for spray foam. Our hot, humid summers put enormous strain on HVAC systems. Spray foam’s air-sealing properties stop conditioned air from escaping and block outdoor humidity from entering — two of the biggest energy loss problems Georgia homeowners face. Homes we’ve insulated consistently see noticeable drops in their Georgia Power bills, especially during summer peaks.
Spray foam insulation can last the lifetime of the structure when properly installed. Unlike fiberglass batts, it won’t sag, settle, compress, or lose R-value over time. It also won’t absorb moisture like fiberglass can. That’s why we back every installation with a Lifetime Material Warranty — because we know it’ll hold up.
For interior spray foam applications, it’s generally recommended to vacate the home during installation and for a few hours afterward while the foam fully cures. We use eco-friendly, non-toxic products, and we’ll give you a clear timeframe so you can plan accordingly. For crawlspace or exterior work, this typically isn’t a concern at all.
Absolutely. Many of our jobs in Gwinnett County are targeted applications — just the crawlspace, just the attic, or just an addition. You don’t have to do the whole house at once. We’ll tell you which areas will give you the biggest bang for your buck and let you decide how to prioritize.
