If you’re a homeowner in Savannah, Georgia, proper insulation is one of the best investments you can make for comfort and energy savings—especially in our hot, humid climate. But with so many insulation options out there, how do you know which type is right for your home?
At Koala Insulation of Savannah, we specialize in helping homeowners make informed decisions about insulation that suit their unique needs. In this guide, we’ll compare the three most popular insulation materials—spray foam, fiberglass, and cellulose—to help you choose the best solution for your home.
Why Insulation Matters in Savannah
Savannah’s summers are long, hot, and humid. Without the right insulation, your cooling system works harder than necessary, driving up your energy bills and reducing your indoor comfort. Proper insulation acts as a barrier, keeping cool air inside and blocking heat and moisture from seeping in.
At Koala Insulation of Savannah, we often find that older homes have insufficient or outdated insulation. Choosing the right material can drastically improve your home’s efficiency and save you hundreds on energy bills each year.
Option 1: Spray Foam Insulation
Overview:
Spray foam insulation is a high-performance material made by mixing and spraying two liquid components that expand into foam. It creates an airtight seal that’s hard to beat.
Pros:
- Superior Air Seal: Great at sealing gaps, cracks, and hard-to-reach places.
- High R-Value: Closed-cell spray foam offers one of the highest R-values per inch.
- Moisture Barrier: Acts as a vapor barrier to keep out humidity—ideal for coastal areas like Savannah.
- Pest Resistant: Creates a barrier that pests have a harder time penetrating.
Cons:
- Higher Cost: It’s the most expensive option upfront.
- Installation Requires Pros: Must be professionally installed for safety and performance.
Best For:
Attics, crawl spaces, rim joists, and anywhere a tight seal is essential.
Koala Insulation of Savannah offers expert spray foam installation using top-tier products that are both safe and energy-efficient.
Option 2: Fiberglass Insulation
Overview:
Fiberglass insulation is one of the most common and cost-effective types of insulation. It comes in batts or rolls and is made of fine glass fibers.
Pros:
- Affordable: Lower upfront cost than spray foam.
- Widely Available: Easy to source and install.
- Non-Combustible: Doesn’t burn easily, adding a layer of fire resistance.
Cons:
- Air Leakage: Doesn’t seal air gaps, reducing overall efficiency.
- Performance Drops When Wet: Susceptible to mold if exposed to moisture.
- May Settle Over Time: Can become less effective as it ages.
Best For:
Interior walls, attics (in dry areas), and new construction projects.
Koala Insulation of Savannah provides professional fiberglass installation to ensure optimal coverage and safety.
Option 3: Cellulose Insulation
Overview:
Cellulose insulation is made from recycled paper products treated with fire retardants. It is commonly blown into walls and attics.
Pros:
- Eco-Friendly: Made from up to 85% recycled content.
- Good Coverage: Blown-in method fills small spaces well.
- Affordable: Costs more than fiberglass but less than spray foam.
Cons:
- Can Absorb Moisture: May retain water in humid conditions if not properly installed.
- Settling Issues: Over time, it can compact, lowering its R-value.
- Needs Air Sealing: Doesn’t prevent air leaks unless combined with sealant.
Best For:
Attics, enclosed walls, and retrofitting existing homes.
Koala Insulation of Savannah uses advanced cellulose insulation techniques that increase coverage while minimizing moisture risks.
