Professional insulation services and energy efficiency solutions for residential and commercial properties.
Spray foam systems offer Atlanta homeowners and businesses a range of performance benefits. Spray foam products serve as an effective thermal barrier, just like traditional insulation materials, while offering additional advantages.

These capabilities define the insulation type:

  • Prevents Conduction: Spray foam reduces thermal transfer from materials in contact with the insulation itself, such as wood or drywall.

  • Blocks Air Infiltration: The insulation system prevents treated air from transferring through gaps, holes, or damage in exterior walls and roofs.

  • Stops Moisture: Spray foam blocks moisture from entering the treated space and contributing to heat loss or gain.

Advantages Of
Spray Foam Insulation in Atlanta

Spray foam insulation outperforms all other types of insulation by large margins because its long-term benefits outweigh its initial installation costs. Spray foam also offers superior sealing properties and is environmentally friendly.

Improved Air Quality Icon
Improved Air Quality

A tightly sealed home prevents dust, pollen, and pollutants from entering. Spray foam insulation improves indoor air quality by reducing air infiltration and moisture, making your home healthier and more energy efficient.

Water & Fire Resistance Icon
Water & Fire Resistance

Spray foam insulation helps safeguard your home against water leaks and offers fire resistance. Its tight sealing properties and mildew resistance offer helpful protection against water damage, making it an especially wise choice.

Pest and Wildlife Protection Icon
Pest and Wildlife Protection

Spray foam insulation helps protect your home from insects and rodents. Its airtight seal and durable structure make it harder for insects and rodents to get inside, delivering long-lasting protection and added peace of mind.

Strengthens Buildings

Spray foam insulation doesn’t just seal air leaks, it reinforces your home’s structure. Once cured, the foam forms a strong, rigid layer that bonds to framing, sheathing, and drywall, helping the entire building resist shifting and settling over time. This added rigidity can reduce wall flex, improve soundproofing, and extend the life of your home.

Soundproofing Icon
Soundproofing

By sealing gaps and spray foam creates a continuous barrier within walls, floors, and ceilings, this insulation helps reduce unwanted noise throughout your home. Its dense structure absorbs and dampens sound waves, effectively muting both outdoor and indoor noise, to HVAC systems and plumbing lines.

Environmentally Friendly Icon
Environmentally Friendly

Investing in spray foam insulation is a proactive step toward a more energy-efficient, resilient home. Unlike traditional materials that may shed fibers, cured spray foam is chemically inert, meaning it doesn’t release harmful particles into your living space. During the professional installation process, specialized equipment ensures a precise application. While a brief “off-gassing” period is standard, once cured, the foam provides a permanent, seamless air seal. Because spray foam, specifically closed-cell varieties, does not retain moisture or support mold growth, it acts as a robust secondary barrier against water damage, preserving your home’s structural integrity for decades.

My experience with Koala Insulation of Atlanta Perimeter North has been nothing less than outstanding !!

I first contact them during the Summer of 2025. Billy came to my house and explained all of the options. I decided to go with the spray foam application to replace 30 year old batts in my attic.

My problem was finding a time (the process took 2 full days plus another day to allow the foam to cure) when I could be out of the house.

I contacted Billy at the beginning of Spring this year. He gave me a revised quote and I scheduled the project. The team came last week. The main technician was Dumitru. He was amazing. His communication throughout the process was excellent. The install team was over the top wonderful, professional and went out of their way to do everything perfectly.

The job went off without a hitch !! I went up to my attic yesterday for the first time since the application. It was hot outside, but not in the attic !!!! I was in the attic for over 30 minutes and never felt uncomfortable !! No sweating, not even a bit !!

I give Koala Insulation a 12 out of 10 !!!

I am so, so, so happy (and the top floor of my house is perfectly conditioned from the hot, muggy, damp Summer outside.

My experience start to finish with Koala of Atl Perimeter North was exceptional. Every team member was polite, professional, communicative and efficient. There was clear and constant communication throughout the process and the price was better than one of their competitors who used pushy sales tactics that pushed me away. I am pleased with the outcome of the spray foam in my attic and I have already recommended Koala to a friend!!!

What a great find! We were having moisture problems..we found that the floor wasn’t air sealed and the insulation was poorly blown in the attic. They vacuumed out the old insulation air foam sealed all the flooring and blew in the new insulation air. Their crew was extremely courteous and knowledgeable. Fantastic clean up.

The crew that came out on a 97 degree day did an excellent job of blowing insulation in my attic. Even though it was extremely hot, they still spent the time to do things right. I was very impressed with their attention to detail. Even though theirs wasn't the lowest bid (nor the highest), I feel the couple hundred extra spent was well worth the money. Professional all the way.

Our experience with Koala Insulation was a breeze from start to finish. Everyone we interacted with was knowledgeable about the product and explained the process thoroughly. Our consultant Billy came out to the house to look at our attic and explain how we could upgrade our insulation, and we were able to schedule install date quickly after. Our installer Brian and his crew were so thorough and left our house as clean as it was before they arrived. Would highly recommend Koala, particularly if you have an older home in need of an insulation upgrade!

I had an amazingly positive experience with koala insulating my attic. Professional, kind, communicative, clean and tidy, respectful to my property. I am waiting for a request for photos of the sealed areas and possibly some additional insulation to some areas that may not be deep enough. I was told photos were to be taken by Billy Addison at time of sale and by installers. I am waiting to pay my invoice to have the photos and any thin areas I failed to mention during final inspection after install. Brian was amazing, he even takes a magnet and collects any nails that fell into surrounding exterior. I would highly recommend.

There is nothing more valuable than ‘service recovery’ as coined by Four Seasons Hotel. Doug and Brian came back to my home and searched for the gap I was concerned about AND repaired it!!!

A+++

I will use them again personally as a landlord and for my real estate clients.

A characteristic of great businesses is how they handle customer complaints. I engaged Koala to upgrade the insulation in our home. Their sales person came and gave me a detailed quote including some free add ons which I accepted.

When their staff came to do the job, I decided to reduce the scope of work. This caused changes in pricing at their end which their ops and billing team were unable to resolve. It took just one email to their customer service and I was contacted by their owner. He resolved everything to my satisfaction.

I found them to be professional, polite, prompt, and knowledgeable. I recommend them highly to anyone considering an insulation job.

I hired Koala of Atlanta Perimeter North to remove loose insulation that had been installed 44 years before and they did a fantastic job. They professionally prepped the area for over an hour before running a hose from outside into the attic. What was originally estimated to be a 2-3 hour job took over 6 hours because the insulation was wet (I'll deal with my bad insurance company about that one) but they are pros and got every bit of the loose insulation out. It was unbelievably heavy. Brian and his protege James did a great job and I'll be asking Ryan, the owner, to send them to install the bats in a few weeks.

Is spray foam right for my attic in Atlanta?

Spray foam insulation can be an excellent choice for attics, but there are a few key factors to consider:

Moisture and Preparation: Any existing dampness or water intrusion should be resolved before installation to ensure strong adhesion and long-term performance.
Surface Readiness: Concrete or masonry walls may need light cleaning or preparation so the foam bonds evenly and seals effectively.

By addressing these factors, spray foam creates a dry, comfortable, and energy-efficient environment that helps protect your home from the ground up. When applied by certified Koala Insulation professionals, spray foam provides lasting comfort, reduced energy costs, and year-round peace of mind. Learn More

How much does spray foam insulation cost in Atlanta?

There are several factors that affect the cost of spray foam insulation. In Atlanta Perimeter North and most cities, insulation costs vary based on the amount of material required (based on square footage), the need to remove existing insulation, and the complexity of the project.

  • Small attic (Less than 500 square feet): $1,000 to $2,000
  • Medium attic (1,000 square feet): $2,000 to $5,000
  • Large attic (2,000 square feet): $4,000 to $8,000

Infographic comparing a standard basement vs. one with spray foam, highlighting moisture barrier, air sealing, and energy savings.
How much does basement spray foam installation cost in Atlanta?

The cost to insulate a basement with spray foam depends on the size of the area, existing insulation, and project complexity.

Small basement (≈500 sq ft): $1,200 – $2,800
Medium basement (≈1,000 sq ft): $2,400 – $5,600
Large basement (≈2,000+ sq ft): $4,800 – $9,000

Spray foam insulation helps eliminate drafts and moisture, providing a more comfortable, energy-efficient lower level. Pricing per square foot may increase if your basement requires old insulation removal, foundation wall prep, or hard-to-reach rim joists.

Should I insulate my basement ceiling with spray foam?

Closed-cell spray foam works best for basement ceilings because it provides a high R-value and acts as a moisture barrier. It can also help block sound between floors. For the best results, it’s important to assess your home’s layout, HVAC design, and moisture conditions before choosing where to apply spray foam.

Koala Insulation technicians can evaluate your space and recommend whether ceiling, wall, or rim-joist insulation will deliver the greatest comfort and energy savings for your home.

Is spray foam insulation safe?

Spray foam insulation is safe when handled and installed by a trained professional. Spray foam poses no health risk once it is cured, but it can be hazardous during installation due to its chemical composition. We follow all industry safety standards, ensure proper ventilation, and complete curing before occupants return to the space, usually 24-48 hours after project completion.

Can you insulate the concrete block walls in my basement?

Concrete block basement walls can be insulated with spray foam, provided the surface is clean, dry, and free of moisture issues. Closed-cell spray foam is typically best, as it both insulates and creates a moisture-resistant air seal that helps prevent mold and drafts. Before application, any existing leaks or dampness should be addressed to ensure long-term performance and adhesion.

At Koala Insulation, we’ll determine whether spray foam, rigid foam board, or a hybrid system is the best fit for your block-wall basement so you get a solution built for long-term performance.

Do My Rim Joists Need An Airtight Seal?

Rim joists absolutely benefit from an airtight seal. Sealing this area with spray foam insulation prevents drafts, moisture intrusion, and heat loss where the foundation meets the framing, one of the most common sources of energy waste in a home. By creating a continuous air barrier, you’ll enjoy warmer floors, lower utility bills, and better indoor air quality year-round.

Is spray foam insulation flammable?

Spray foam insulation itself is not flammable once fully cured, but like most building materials, it can burn when exposed to direct flame. Koala Insulation uses fire-rated, code-compliant products. When installed correctly by our certified technicians, spray foam insulation provides a safe, durable, and energy-efficient layer that meets modern fire safety standards.

When installed correctly by our certified technicians, spray foam insulation provides a safe, durable, and energy-efficient layer that meets modern fire safety standards.

Infographic explaining how to paint spray foam insulation using latex or fire-retardant paint like DC315 for UV and surface protection.
How long does spray foam insulation last?

Spray foam insulation typically lasts 80 to 100 years when professionally installed and properly maintained. Spray foam adheres directly to the building structure and won’t sag or settle, which means it offers the same performance decade after decade.

What are the best applications for spray foam insulation?

Spray foam insulation is a premium, versatile option for a few specific applications. After your initial assessment, we may recommend spray foam for:

Attics: Open-cell spray foam on attic floors seals air leaks and prevents treated air in the living space from escaping into the attic.
Basements: Closed-cell spray foam acts as a vapor barrier in moisture-prone basements, crawl spaces, and cellars.
Exterior Walls: While not always necessarily the most cost-effective option, spray foam fills irregular gaps in wall cavities while providing an effective moisture barrier.
Floors: Spray foam is sometimes sprayed between floor joists in suspended timber floors (non-slab).
Roofs: Closed-cell spray foam installed under the roof deck prevents air leaks and protects against moisture issues.

Can I spray foam insulation myself?

While DIY kits exist, spray foam insulation is not a good do-it-yourself project. Professional installers have the training, equipment, and ventilation controls needed to ensure safety, proper curing, and compliance with building codes. Poor installation from DIY attempts can lead to moisture problems, off-ratio foam, or even voided home insurance coverage, making professional service from Koala Insulation technicians the smarter, safer choice.
