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 Birmingham

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 well-sealed home significantly reduces the infiltration of dust, allergens, and other potentially harmful substances. Implementing spray foam insulation can enhance indoor air quality by minimizing air leakage and improving humidity regulation. This results in a healthier home environment and increased energy efficiency.

Water & Fire Resistance Icon
Water & Fire Resistance

Spray foam insulation serves as an efficient method for safeguarding your home against moisture while offering fire-resistant properties. Its capacity to form a tight seal helps to inhibit mold development, making it a superb option for reducing water damage and improving the overall safety and comfort of your living space.

Pest and Wildlife Protection Icon
Pest and Wildlife Protection

Spray foam insulation serves as a reliable defense against pests such as insects and rodents. Its comprehensive application creates a continuous barrier that significantly lessens the likelihood of these unwelcome visitors gaining access to your home. This durable type of insulation not only improves the comfort of your living environment but also provides long-lasting protection, ensuring you have peace of mind for years to come.

Strengthens Buildings

Spray foam insulation is essential for effectively sealing air leaks and improving the overall strength of your home. Once it is applied and completely cured, the foam forms a robust layer that bonds tightly with the framing, sheathing, and drywall. This strong connection enhances the stability of the structure, making it more resilient to movements and settling over time. The increased rigidity helps reduce wall movement, improves soundproofing, and contributes to the durability of your home.

Soundproofing Icon
Soundproofing

By sealing gaps and utilizing spray foam insulation, you create a seamless barrier in the walls, floors, and ceilings of your home. This insulation method is highly effective in reducing unwanted noise throughout your living environment. Its dense structure absorbs sound waves, leading to a marked decrease in disturbances from external sources as well as internal noises such as those from HVAC systems and plumbing fixtures.

Environmentally Friendly Icon
Environmentally Friendly

Choosing spray foam insulation is a sustainable investment for a more energy-efficient and resilient Birmingham home. Unlike traditional materials that may shed fibers, cured spray foam is chemically inert, ensuring it doesn’t release harmful particles into your living environment. Our professional installation process uses specialized equipment to ensure a precise application, and while a brief off-gassing period is standard, the result is a permanent, seamless air seal. Given Alabama’s humid climate, closed-cell spray foam is particularly effective as it does not retain moisture or support mold growth, acting as a robust barrier against water damage and preserving your home’s structural integrity for decades.

I chose Koala Insulation of Birmingham to add insulation to my attic space, and to install a zippered insulated attic stair cover to prevent drafting into my living space. This company responded promptly to my request for a quote, completed the job in a professional manner, and their technicians cleaned up immaculately. This is NOT easy work, especially in the summer in Alabama. Neal did the quote and provided me with several options to consider to help lower my utility costs. Their receptionist Bethany, was absolutely a pleasure to work with and kept me informed every step of the way. Their technicians came on time, relentlessly did their job in sweltering heat, and were respectful of the property in every way. I am glad I chose this company - - - their employees autograph their work with quality.

The reason Koala has only 5 star reviews is because they deserve only 5 star reviews. Neal came out and checked out my attic insulation, had a quote sent to me, they worked with me on the quote, and came out for the installation.

The installation was very fast - showed up at 7:30 and done by 10:30. Everything was very clean too.

Then, when I had concerns about the newly installed attic insulation, John and his crew came out, inspected the job, and addressed all of my concerns.

Koala has been amazing to work with! We recently purchased a 20-year-old home and I desperately needed insulation added to my attic as it was patchy or just missing in whole sections. Our AC was working too hard when it was just 82 out and couldn't keep up.

Kim in the office has been so patient and helpful. I really appreciate her kindness handling our set up!

Patrick and Martin were wonderful to work with. They were very patient, went above and beyond, and reviewed the work with me to make sure I was happy before they left. They were so quick too! They also made sure to clean up before they left.

The results are worth it! They left around 9 or 10 this morning and I can already tell a huge difference. A room that would get to be about 80 with our AC running and curtains closed got down to 73 today with the AC set to 73. It's such a relief. I'm thrilled to finally enjoy all of my new-to-me house.

I highly recommend this team to improve your home. They're competent, reliable, and efficient. I would love to work with them again!

First of all Koala is a small business, family owned which earns points with me. I was on the search for a company that didn’t have all these negative remarks online. When I retired I moved back into the family home. I found myself blowing my nose at least 20 to 25 times a day, this had never happened. I asked my Mom about the attic insulation. She replied “oh yes, I had that done 10 years ago”. Ok, so I’d scratch that off the list. Another year goes by, still the same persistent nose blowing. I told myself this can’t be right. When I got up in the attic, I was horrified. The workers took advantage of my elderly mother. They just started tossing pink bats on top of insulation that had been up there from the 1940s! The good news was my mother said her father installed Cellulose insulation and the old was not asbestos. The workers 10 years ago only covered ¼ of the attic space. Not only did charge my mom for the entire area, they left all the old insulation from the 1940s up there! In all my research, Koala stood out. From online positive reviews to the process of the work they performed. But here is where Koala went the extra step; they would completely vacuum the entire attic space before putting down the new insulation. The guys that work for this company take a lot of pride in being meticulous, which I greatly appreciated. Both of the attic fans which I was unaware of did not work and I asked about a replacement. They carry solar fans that have a solid life span and are tax deductable; I believe it was 30%. I had them install a cover sealer that incased the top of the stairs (we have the pull down type) so AC and heat wouldn’t escape into the attic saving us money in the long run. Now down to the insulation. You can use the pink kind, that is fine and it’s cheaper but I went with the blown Rockwell insulation. Water cannot soak it and it can’t burn. I asked Koala for a price comparison between the pink and Rockwell which they were glad to do. I was pleasantly surprised it was only about 2k more. Now here this, I am a fan of Rockwell from all my research. It’s more efficient, repels water, won’t burn and it’s last LONGER than the pink. So, in the long run it does come out cheaper. Now let’s talk about the workers at Koala. The workers at Koala take such pride in their work, cleaning up as they go along and not leaving a mess was impressive. They were kind, respectful to me and to the property. I would tell everyone you don’t need to look any further and you can depend on Koala. They even installed these rulers throughout the attic so you could see the exact depth that was blown in. I can’t speak enough on how wonderful the experience was. Go to Google online and see for yourself all the positive reviews.

We have had a wonderful experience with this company from start to finish. The quote for increasing our attic insulation to R-38 was very competitive and included a solar-powered vent. They were able to begin the job within a week. All of the employees were very professional and polite, and explained what they were doing. After finishing they ensured their work area was cleaned up completely. The completed job looks amazing and our upstairs A/C unit is no longer straining and running all day trying to cool the upstairs portion of our home. Thank you Koala for doing such a great job. I highly recommend them and would not hesitate to use them again in the future.

My experience with Koala Insulation was stellar! From estimate to installation. I also got much more for my money in comparison with another well known company!

Communication was super quick and less than 48 hrs after my initial online inquiry Neal was at my house giving a free estimate. He was SUPER thorough. He spent over an hour at my house. First waking the entirety of my attic in the blazing summer heat, taking pictures of everything, and then talking through all his recommendations for my particular setup and different options he could quote. Very friendly and helpful and made me want to use them even before seeing the actual price. Which again, ended up cheaper than others I asked!

Jonathan, Cole, and Ryan continued the positive experience with their on time and quick installation. Communication with Jon and Bethany regarding when they would arrive was quick, clear, and accurate. The install crew was also very friendly, professional, and kept me well informed about what all was going on which I always appreciate. They were in and out quickly and cleaned up after themselves.

A short while later, the second crew arrived to install the solar fans I opted for. They were equally friendly and professional and got things done quick. Both phases of the project done in the same day!

I chose to leave this thorough review because I have nothing but positive things to say about Koala and always want to share and support companies when that is the case!

The crew at Koala insulation did a great job. The first good impression was, they worked well my schedule. The salesman was able to meet with me at 5 o'clock on a Monday and the installation team came on a Friday morning. The installation team was very respectful of my property. They took the time to insure that nothing was damaged or left in a mess. The owner was polite and quickly responded when I had questions via email or phone call. I would definitely recommend Koala insulation to anyone in need of their service.

Is spray foam right for my attic in Birmingham?

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

Is spray foam right for my basement in Birmingham?

Spray foam insulation is an excellent option for basements, offering both energy savings and moisture control. Here are a few important considerations:

How much does basement spray foam installation cost in Birmingham?

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

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.

Can you paint spray foam insulation?

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.
