A Superior
Thermal & Air Barrier Services in Texas Hill Country
Spray foam systems offer Texas Hill Country 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 that are particularly effective against the intense Texas heat.
These capabilities define the insulation type:
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 Texas Hill Country
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
A properly sealed home in the Texas Hill Country prevents cedar pollen, dust, and outdoor pollutants from entering your living space. Spray foam insulation improves indoor air quality by reducing air infiltration and moisture, making your Hill Country home healthier and more energy-efficient against the extreme Texas heat.
Water & Fire Resistance
Spray foam insulation is an effective solution for protecting your Texas Hill Country home from moisture intrusion while also providing resistance to fire. Its ability to create a secure seal and resist mold makes it an excellent choice for preventing water damage and enhancing structural safety, ensuring a comfortable living environment that stands up to the unique regional climate.
Pest and Wildlife Protection
Spray foam insulation provides an effective barrier against pests common to the Texas Hill Country, such as scorpions, rodents, and insects. Its seamless application creates an airtight seal that eliminates entry points, helping to protect your home from unwanted visitors while enhancing overall structural integrity and energy efficiency.
Strengthens Buildings
Spray foam insulation provides more than just an airtight seal; it reinforces the structural integrity of your Texas Hill Country home. Once cured, the foam forms a rigid, durable bond with framing, sheathing, and drywall, helping your property resist shifting and settling during extreme temperature fluctuations. This added rigidity helps reduce wall flex and vibration, providing a quieter, more stable living environment built to withstand the unique demands of the regional climate.
Soundproofing
By sealing gaps and creating a continuous barrier within walls, floors, and ceilings, spray foam insulation significantly reduces unwanted noise throughout your Texas Hill Country home. Its dense structure excels at absorbing and dampening sound waves, effectively muting both outdoor disruptions and internal noise from HVAC systems and plumbing lines to create a more peaceful living environment.
Environmentally Friendly
Investing in spray foam insulation is a proactive step toward a more energy-efficient and resilient home in the Texas Hill Country. 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 our professional installation process, specialized equipment ensures a precise application that creates a permanent, seamless air seal to combat the extreme Texas heat. Because closed-cell spray foam does not retain moisture or support mold growth, it acts as a robust secondary barrier against water damage, preserving your Hill Country property’s structural integrity for decades.

This company really knows what they’re doing! Very straightforward assessment and estimate given. The crew showed up on time and had to work done quickly. They also did a nice job cleaning up any of the installation that was on the ground. I would definitely recommend them if you need attic insulation.

We recently had our attic insulation replaced and couldn’t be happier with the results. The crew was accommodating, reliable, gave advanced notice before their arrival and arrived on time, walked us through the process before starting, and worked efficiently with minimal disruption to our day. Communications from different Koala representatives were excellent every step of the process from the initial evaluation to the day of service. Special thanks to Andrew, Anthony, Sergio and Arthur for your professionalism, expert knowledge, and hard work especially in this Texas heat. I highly recommend and trust this team to anyone seeking Koala services.

"Professionals," from start to finish. It was a matter of minutes after sitting down with Andrew that we knew that we would be doing work with his company. The labor was approachable, punctual, detailed, and thorough. There were no new price increases, or needed work after our first consultation. The quality of work was more than what we hoped for. I highly recommend this company.

65 years old home with probably 65 years old blown insulation. Koala insulation was quick to respond and provide data and visual information that showed all the hot spots that were plaguing our house.
They were able to draw up a solution based upon the extreme temperatures and architecture of the house in order to substantially reduce the trapped heat before the Texas summer heat really kicks in.
Pricing was fair and we were not pushed or pressured to buy beyond our budget.
Excellent communications and superb client service to enhance their customer experience.

Koala Insulation dba Java Corp did an excellent job bringing our attic insulation up to date.
They were on time, completed their work on time and left our home clean.
This contractor I would highly recommend!
Very thorough pre-inspection of our attic and what was needed to be taken care of. Then Andrew sat down with us and explain exactly what was needed and why, then followed up with a detailed written bid. We got three bids and they were right in the middle and very competitive. We are extremely happy with the work that they did and we are glad that we chose them.

They do not hunt you down to be able to sell… Had a really good experience with Koala Insulation. Andrew was honest and didn’t try to upsell me at all. He explained exactly what insulation I have, the levels, and where I stand, I felt supported and comfortable to trust his expertise.
I’m on the lower side, but he was very clear it’s not urgent and I don’t have to do anything right now. Even told me I could wait until June/July and see how the heat feels, then decide.
Gave me options, pricing was fair, and overall just very helpful and professional. If I end up needing it later, I’ll definitely go with them, no doubt.

Koala did a fantastic job on our Attic Insulation upgrade. From the prompt, detailed inspection, through the recommendations, estimate, and agreement, Andrew was extremely professional and detail oriented.
Frank and Sergio showed up on the agreed date and time, and got to work. We hardly noticed they were here, but they were hard at work, and completed our job by lunchtime. Professional, pleasant, and patient, they answered a few questions, which confirmed that they were well informed of the specifics of our job.
Job completed, our paperwork was promptly sent, and included all the details needed for a Rebate from our energy provider, CPS Energy in San Antonio. The Rebate was approved in less than 24 hours, and I am looking froward to smaller eneergy bills, and Rebate money to help pay for our bills.
And possibly a tax break from the IRS on our 2026 taxes. We will confirm that with our tax preparer next year. Koala also provides all this info on their web site. It really helps reduce the direct cost for the insulation upgrade.
Thank You, Koala - I wish all companies were this easy to deal with.

Koala is the best and most honest attic insulation service in San Antonio. Andrew was knowledgeable, and advised us in what insulation we needed.
In our home, we essentially had no insulation. We had some old cellulose from the 80’s that had degraded down to less than 2 inches in depth. Let me tell you, when it was hot, our house was hot, when it was cold our house was cold.
Initially we were thinking about getting spray foam insulation, (which other companies had recommended for us to do AND QUOTED US FOR IT), but Andrew explained that spray foam wouldn’t work in our house since our attic has a gas furnace and gas water heater, so they would be starved for air, and it would ruin essentially thousands of dollars in equipment. He recommended that we use blown-in insulation because that’s what the house was designed for. So we went for it.
Frank and Antonio arrived on time and were very professional. They were thorough in making sure that the attic was cleaned before they started working. They then added tubing to the bathroom exhaust fans so that they went above the insulation (they were buried before they came). After blowing the insulation they vacuumed the carpet from where they entered the attic, and made it look like they were never there.
Let me tell you, I’ve been sleeping better because our house isn’t having these huge temp swings that used to strain our ac unit. I would recommend Andrew and his team again and again for insulation services here in San Antonio.

Wonderful working with this company. Andrew gave a thoughtful, clear understanding of our roofs insulation needs. Arthur and Antonio were a prompt, detailed, polite and neat install team. That neatness was so welcomed! Not one speck of stray insulation. Don't hesitate to use this company, great work!

We called Koala for insulation work but had a special request. We asked for all the old insulation to be removed on one day while we had a/c work completed and then asked them to return after that work was completed to install new insulation. Without an issue Koala competed the 2 jobs without a problem. They accommodated us on dates/times and the did a fantastic job. Seriously one of the best vendors we've used in a long time. I highly recommend them and will use them for any insulation needs I have moving forward.

Inquired on several contractors for attic blown-in insulation estimates. Ended up choosing Koala Insulation through Lowes projects. Did find price estimate to be very reasonable plus loved how they used Johns Mansfield product. As courtesy, the team re-taked some radiant barrier that was loose, bravo. Entire project took about 2 hours to complete. Existing R-Value of insulation before project was R12 at 0-6" attic coverage. Goal was to get at least to R-38. Attic coverage after project done is significantly improved. Would definitely suggest Koala for any residential or commercial insulation needs for service.

Andrew and his crew were friendly, prompt, competitively priced, and extraordinarily accommodating. They cleaned out the old, sealed the space and blew in new insulation on the same day for exactly what the estimate said. They later returned after some trades had compacted the freshly blown insulation and did the repair installation for cost, ensuring we’d be ready for city inspections. We really appreciate the work they did for us.

He was kind, professional, and took the time to explain everything clearly and gently. In today's world, it's rare to find a company that treats everyone with respect regardless of gender, and I truly appreciated how he communicated with us without any assumptions. I highly recommend Koala Insulation for their exceptional service and honest, respectful approach.

Very happy with the entire process.
I contacted Lowe's who recommended Koala and was contacted quickly by Andrew to set up a time for project review.
Quotes were provided for several options. Once I made a decision and accepted the proposal the job was scheduled quickly.
The installers, Ezra and Anthony arrived on time and immediately went to work and didn't stop until project completion and clean up.
Everyone I worked with From Andrew the owner, Gary the GM and the installers were professional and great to work with.
Definitely recommend these folks.

I had a recommendation to use Koala Insulation from a family member who had used Koala's services. I was able to get a quick appointment for an estimate, done by Austin. I was pleased to receive texts from the company, keeping me informed of who to expect and what time. The quote was reasonable and work was done the next day. The entire process has been well handled by a professional staff, Austin, Arthur and Sergio, who installed the insulation and solar roof fan. They all were helpful in explaining the different insulation options and answering questions. The company owner, Andrew, was very helpful in providing all the necessary paperwork needed for me to apply for a CPS rebate. They provided a pleasant home improvement experience, well done!

Not the cheapest home upgrade but well worth it. We had Koala come out this past March to top off our attic off with blown in fiberglass. They did a great job. Very professional and left our home clean. They also added a solar fan to help pull the heat out. Now that we have had some heat, I can say it has made a huge difference. Our AC's are not working near as hard and our home is overall very comfortable. Last summer we could not get below 80 degrees until late evening.

Koala Insulation was the #1 choice out of five companies I researched. The owner (Andrew) was professional, fair and reasonable pricing and supports military with a discount. He was awesome, friendly and explained everything in detail. The three man team came out the next day after I confirmed the work. The team was professional, friendly, answered all my questions and cleaned up after they finished insulating two walls.
I recommend this company they are a 5 out of 5!!
I am going to use Koala Insulation again for my future projects.

Is spray foam right for my attic in Texas Hill Country?
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

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.
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.
