Your Blown-In Insulation Team in the Fox Valley
The Fox Valley’s short, humid summers and long, frigid winters can make your home feel uncomfortable and your furnace work overtime. Yet plenty of local attics hold just a few inches of old, settled insulation, well short of what today’s guidelines call for.
Best uses for blown-in insulation:
Attic floors to quickly boost your R-value to modern standards.
Wall cavities in certain retrofit projects, following industry best practices.
Knee walls & sloped ceilings for those hard-to-reach areas.
A Superior
The Thermal Blanket Effect
Blown-in insulation gives Fox Valley homeowners and businesses an efficient shortcut to a more comfortable building. Because the material is blown in loose, it fills low spots and gaps that rigid products leave behind, forming one continuous layer of protection over new or existing insulation.
These capabilities define the insulation type:
Fights Drafts: Combined with strategic air sealing, blown-in insulation limits infiltration around penetrations and top plates, keeping the air you have paid to heat or cool inside your Fox Valley home.
Manages Moisture: A properly installed blown-in layer, paired with healthy attic ventilation, helps limit the condensation and moisture migration that erode insulation performance in the Fox Valley over time.
Advantages Of
Blown-In Insulation for Homes in the Fox Valley
For homes in the Fox Valley facing short summers and long, frigid winters, blown-in insulation delivers a lot: it is fast to install, layers cleanly over existing material, and helps lower heating and cooling costs while keeping rooms comfortable in every season. Key benefits include:
Improved Air Quality
Because our crews air-seal key attic leaks before blowing insulation, the upgrade also helps keep dust, pollen, and other outdoor pollutants from sneaking into the living spaces of your Fox Valley home through ceiling penetrations.
Water & Fire Resistance
Safety first, always. The loose-fill products we install are designed for fire performance, and our crews follow manufacturer guidelines and local code requirements around recessed lighting, chimney chases, and other heat-producing fixtures on every project in the Fox Valley.
Pest and Wildlife Protection
Worried about unwanted attic guests? Cellulose is the one blown-in material treated with pest-deterrent additives, and pairing it with thorough air sealing helps keep insects and critters out of attics in the Fox Valley.
Soundproofing
Noise reduction is a welcome bonus for Fox Valley homeowners: the dense loose-fill layer soaks up outside sounds and dampens noise moving between levels, from street traffic to kids playing overhead.
Environmentally Friendly
Green credentials come standard: the blown-in materials we install are made from recycled content, and the efficiency they add does the rest. Studies have shown insulation can cut heating and cooling energy consumption by up to 40%, which means a smaller footprint for your Fox Valley home.
The Fox Valley’s Stress-Free 4-Step
Blown-In Installation Process
Free Attic Assessment
Before any work is quoted in the Fox Valley, our efficiency experts complete a detailed assessment of your home’s current insulation and energy performance.
- Careful Prep Comes FirstPreparation sets up everything that follows. We shield floors and walkways, establish safe access, and distribute depth markers across the attic to verify the target level later. If the eaves of your Fox Valley home need them, baffles go in to keep insulation clear of the soffit vents.
Koala Difference: We carefully protect your home and prepare the area so your new insulation performs as it should, and your Fox Valley home is not left covered in dust when we are done.
- Seal the Leaks FirstWith prep done, sealing begins. Our team uses thermography to spot the leakage paths (plumbing penetrations, wiring runs, can lights, attic openings) and seals them before a single bag of insulation is blown into your Fox Valley home.
Koala Difference: Anyone can add material. Sealing first is how Fox Valley homeowners get full value from every inch of new insulation.
- Install to the Target DepthOur crew blows insulation evenly across the attic floor, building to the specified R-value while working material into corners and around obstructions. Depth markers are checked continuously so the finished blanket is consistent from eave to eave in the Fox Valley.
Koala Difference: Thin spots quietly steal performance, so we measure and verify until coverage across your Fox Valley home is truly uniform.
- Wrap Up & Review
After installation, we vacuum and tidy the work area, remove equipment, and make sure your attic access is sealed properly. We will review what we did, show you before-and-after photos (when available), and answer any questions about maintaining the new insulation in your Fox Valley home.
Koala Difference: Consider us a long-term resource: future questions, maintenance advice, and guidance on rebates or tax credits that may apply to your project in the Fox Valley.

Really pleased with the job done on my attic insulation replacement. The crew was fast and professional — in and out in just six hours for a full attic insulation removal and replacement, on a job that was less than ideal to say the least.
Scott and Aaron went above and beyond, helping out with a few extra things that weren't even part of the original scope at no extra hassle. It's clear they take pride in doing the job right and helping their customers out. A few unexpected issues came up during the job, but they communicated clearly and resolved everything easily, walking me through each step of the process along the way.
Highly recommend this team if you need attic insulation work done right, quickly, and by people who actually care about doing a good job.
Thanks guys!

Brian was excellent to work with. He spent the time to go over the process of raising concrete on parts of my driveway and entry area. He was able to make the concrete level almost as good as new. He gave us the estimate and did the work after only 5 days and that was with the 4th of July during that timeframe. I would highly recommend them for all your raising concrete and insulation needs.

I recently had my garage insulated and drywalled using Koala Insulation and O@O Painting and Dry wall. My experience started with Justin, who came to my home and gave me detailed quotes for insulation options. He also recommended the drywaller, who I went with as well. The crew came in full force ready to work and assisted me mov in things in my garage. The job was finished in 1.5 days, which included spray in foam and pink insulation. I was very happy with the crew, who were very respectful and cleaned up any mess. The crew also helped me with moving things back into my garage and attic. I was happy with the price, effort and professional job. With Koala, I was able to knock out two projects in one week. Would highly recommend this company. Thanks guys

We would highly recommend Koala Insulation! Brain Aho thoroughly explained the type of insulation we should use for our house and how long it would take to install the insulation. Crew manager Aaron Zack did an awesome job with his crew. The crew showed up on time, worked efficiently, answered all questions we had, and always cleaned up each night.
We had the work done early Feb. 2026 and already feel the difference in our house temperature. Furnace is running less, as well.
THANK YOU Koala Insulation for making our house more comfortable!

The team at Koala was very quick at responding to my inquiry to getting my box sills spray foamed. They also were great from the scheduling standpoint, and we did shift the dates due to extreme temperatures (-15F), but they worked with me to reach my timeline needs and keep my project moving. The guys did a great job at installing the spray foam and protecting and covering up everything. Overall, Koala provided a quality service at a great price!!

Had our attic insulation install done by Jaxon, Aarron, and Logan. They were super friendly and worked efficiently. They did a great job making sure I was informed on the progress of the project. Koala Insulation company was great to work with, straightforward quote and pricing. I cant wait to see the changes in our energy bill now that we have proper insulation in our homes attic!

The process was professional from start to finish. The office called immediately after we inquired about their services. They came out and looked over our attic and gave us a quote before they left our house. The price was right in line with other quotes and we had a few extras done for the price others were quoting. The install crew was awesome. Faster than expected install and clean up was great. Thanks for the great service Koala.

We have a crawl space Brian and his crew had to do, and not a fun job for them I would say. They did a amazing job!
I can't wait to see what it does for our drafts we have been feeling this winter and the fuel bill. I know the furnace is running less!!
Thank you Brian & his crew @ Koala Insulation of the Fox Valley

I was impressed with Brian Aho during the initial site visit to get a quote. He listened to my concerns and was able to answer all my questions. Brian quoted the job based on what I wanted done, he did not try to upsell anything beyond what I asked. The communication was very good throughout the entire process. The installers, Jaxon & Logan were very professional, polite, on time, and kept me up to date on the progress of the project during the day. The truck, trailer and equipment were all in very nice condition. They were efficient and considerate within my home. I have a winding staircase with freshly painted walls and somewhat fancy trim work, and Jaxon & Logan were very careful handling their very long blown insulation hose through my front entrance while navigating it up to the second floor attic. They cleaned up after themselves to the point that when they left, I couldn’t even tell they were here. Nice work start to finish. I would recommend Koala to my friends and family without hesitation.

We had insulation blown into two attics. Both of which were not that easy to get into. Both Jaxon and Logan were courteous, and knew their job well. Could answer questions easily. They cleaned up nicely after themselves. All in all very nice young men. And the job was done efficiently and perfectly. Would highly recommend Koala insulation. Customer service from start to finish was seamless.

The company is amazing! Brian told me what was wrong and what the plan was without being a salesman. He didn't try to push anything that I didn't need. He answered all of the questions I had before the team came over and was extremely responsive. The price for the repair was incredibly reasonable. I would recommend them to anyone that needs work done!

We hired Koala insulation of the fox valley to insulate our entire crawl space at our cottage. They sprayed the under floor between all floor joists, the rim joist all the way around. Laid down thick plastic over the stone floor and up the block wall a little and then sprayed the entire block wall to create a nice seal. We are very pleased with the quality of work. They left our property spotless. Brian was great at keeping us informed at every step. We give them the highest rating as they were a great company to work with and the price was reasonable.

The Koala insulation was great from start to finish. Holden came on with a great estimate and was able to take care of everything I needed done on a very timely manner. The crew that did the job was very polite and professional. Made sure everything was cleaned up and put back. They explained everything they did from start to finish. I can’t Thank you enough for a great job. Thank you Jaxon, Travis and Josh.

When I called Koala Insulation I was able to get an appointment quickly. Brian came to my home, did his inspection and provide me with photos of what was going on in my attic. He explained to me their process and what they could do, to solve my issue. The installers, Jackson, Josh and Travis were professional, friendly and cleaned up after the job was completed. The best part was their price was 60% less expensive to the other bids I received. I would definitely recommend Koala.

Father and two young adult sons manage and operate the business, which is awesome. On my project, one son met with me in person to review the project and provide an estimate, and father and the other son completed the installation of 3" of spray foam in a large pole building. Happy with the work and happy to support this family run local business!

We are absolutely thrilled with the recent installation of attic insulation and a solar attic fan by Koala Insulation! The crew was professional, efficient, and clearly explained the entire process. The solar fan is a fantastic addition, operating completely off the grid and providing excellent ventilation. We highly recommend Koala Insulation to anyone looking to improve their home's energy efficiency with quality attic insulation and a solar attic fan!

I recently purchased a home and the insulation in the attic was only about 3 inches thick. I shopped around to get some quotes. Koala was my first company that responded immediately and got something scheduled for an inspection. Holden came out and spent about 2 hours with me. He went through the entire project from A to Z. I was really impressed with him. I had my other companies come out but nothing compared to what Holden presented to me. They came out today to blow in the insulation. Brian who owns the company and his other son did an amazing job. It took them less than 5 hours. I love that this is a family owned business. I can’t recommend them enough.

What Does Blown-In Insulation Cost in the Fox Valley?
Rather than quote a flat rate, we price every blown-in insulation project around a few specifics.
Square footage sets the baseline, the type of insulation (such as cellulose or fiberglass) shapes material costs, and the effort required to install it, things like attic access, prep, and air sealing, rounds out the scope.
Whatever the scope, the upgrade works in your favor over time: better attic coverage means less heat loss and lower heating and cooling bills.
Many state and local governments and local utilities also offer rebates or incentives that can offset a portion of the project. For a firm number on your Fox Valley home, skip the guesswork: contact us for a free assessment and a quote built on your actual attic.
Blown-In Insulation vs. Rolls: Which Is Better?
For attics, blown-in usually wins. Loose-fill flows around joists, wiring, and pipes to form one continuous blanket, while rolls (batts) tend to leave small gaps at edges and obstructions. In attics in the Fox Valley, those little gaps add up to drafts, uneven rooms, and performance below the rating on the package.
How Much Blown-In Insulation Does My Attic Need?
The right amount comes down to three inputs: the square footage of the space, the insulation depth required, and where you live (see the map below). Climate drives the recommended attic R-value, with colder regions needing thicker insulation to slow heat loss and warmer regions needing enough depth to block heat gain. Attic size and target R-value together set how much material consistent coverage requires. The Fox Valley falls in Climate Zone 6A (cold) on the DOE/IECC map, where recommended attic insulation runs roughly R-49 to R-60 per ENERGY STAR guidance.
That is why professional installers do not eyeball it: material calculations follow climate-zone guidelines, current insulation levels, and manufacturer coverage charts. Done right, the depth matches the recommended R-value for your area, allows for natural settling, and leaves no thin spots to drag down performance. The diagram below shows how recommended attic insulation levels change by geographic region, helping homeowners understand why insulation needs differ from one location to another.
