What to Expect
In 5 Easy Steps






Your Satisfaction is Our Top Priority

Spray Foam Insulation
Spray Foam is a two-part product that is heated and then is sent through a hose into the stud cavity, where it hardens in a matter of seconds and creates a long-term barrier that keeps your home comfortable and energy efficient.

Blown In Attic Insulation
Consisting of small pieces of insulation, this type of insulation can quite literally fill every nook and cranny of a space and create an uber-fluffy layer of effective insulation. Our technicians ensure your attic, wall and ceiling cavities are filled correctly and without gaps or voids.

Insulation Removal Services
If you’re experiencing moisture damage, pests, mold, diminishing efficiency, or other problems, we’ll remove existing insulation, and sanitize and deodorize the areas.

Batt Insulation Installation
One of the most recognizable forms of insulation. Batt comes in large rolls or pre-cut sections that are typically pink or yellow in color. These are installed in sheet form and laid out between the studs in walls, floors, and attics.

Solar Attic Fans
Solar attic fans turn your attic into a livable space by pushing hot air out and pulling cool air in. Our fans use solar energy to keep your attic at a comfortable temperature year-round.

Air Sealing Service
We identify and seal leaks letting air in and out of your home to reduce unwanted temperature loss or gain.

Crawl Space Encapsulation
Keep your crawl space dry and your floors warm with vapor barrier crawl space insulation that helps you save energy.

Commercial Insulation Services
Give your workspace a boost with our commercial insulation services. Whether you’re upgrading an office, retail space, or industrial facility, we’ve got solutions that fit your needs. Our goal is to help you create a comfortable space while cutting down on energy costs, so you can focus on what you do best.

Causes of Poor Insulation
Most of the time, poor insulation is unpreventable. Insulation can fail even if you keep your home in good condition and stay on top of maintenance. Here are a few primary causes of poor insulation:
- Age: The fibers of insulation deteriorate over time. Once the fibers degrade, the insulation doesn’t work as well.
- Outside Contaminants: Tiny cracks and crevices in your home’s exterior may allow pests, dirt, and moisture to enter the insulation, reducing its efficiency and speeding up the natural deterioration process.
- Electrical Stresses: Overvoltages, electrical impulses, and surges can damage the structural integrity of the insulation.
Services Offered
Koala Insulation provides comprehensive insulation services for homeowners in the Northern Illinois area.
- Blown-In Insulation: We use a wide hose to cover the cavities of attics, walls, and ceilings with Blown-In Insulation. Made from cellulose, mineral wool, denim, or fiberglass, Blown-In Insulation creates a thick, fluffy layer that fills any gaps or crevices.
- Spray Foam Insulation: This type of insulation is created from spray polyurethane foam (SPF), which hardens against walls. The thick barrier is especially good at reducing noise between rooms and minimizing temperature fluctuations.
- Batt Insulation: Our Batt Insulation comes in pre-cut rolls and sheets, which we install between the studs of your house. You can choose between fiberglass, mineral wool, or organic cotton.
- Air Sealing: A high-quality air sealant can plug holes and gaps commonly found in doors, windows, recessed lighting, attic hatches, and other areas. Air sealing further improves the efficiency of your home’s other insulation practices.
- Insulation Removal: If you need to remove old or damaged insulation before your new insulation is installed, we’ve got you covered. We remove insulation damaged by age, pests, and electrical stresses, then thoroughly clean and sanitize the area.
- Solar Attic Fans: A hot attic traps air, increasing temperatures throughout the house and potentially damaging ductwork during summer heat waves. Installing a Solar Attic Fan enhances air circulation and improves attic insulation efficiency.
- Crawl Space Services: Leaks in the crawl space can allow air and foreign contaminants to enter your home. We’ll inspect the area for leaks and install crawl space insulation where needed.
- Builder Services: We collaborate with local builders on residential, industrial, and commercial insulation projects.
