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.

We got several quotes for an attic insulation upgrade. Koala was very through in inspecting the attic and then educating us on the work to be done. Koala completed the project promptly and the crew cleaned up thoroughly when they were done. We were provided with before and after pictures showing details of what was done. They also installed a solar powered attic fan that is very quiet and effective compared to our old one.
Thank you to Chris and his attentive staff!

The Koala Insulation Team (Pablo, Aidan, Chris M. and C.J.) spent 1.5 days in our home. They displayed a wonderful professional attitude: prompt, friendly, wise and hard working.
Our project was a bit different than most, as the CJM Roofers needed to open an area of our roof so Koala could do their work in an otherwise inaccessible attic space.
The Koala Team worked in tandem with the roofers to complete their task in a timely manner without causing delay with the overall project timeline saving us $.
So well done!
Grateful and would highly recommend Koala Insulation of Northern Illinois for your project!

The Koala Insulation team (Aidan, Nate, Christopher and Chris) were extremely polite and professional, not to mention these guys hussle. They tested my home's air flow, sprayed sealed around the electrical fixtures in the attic, verified that the baffles were unobstructed & secured and topped off the insulation. Then the absolute cherry on top was the solar powered attic fan. This fan totally exceeded my expectations. It has totally changed the level of comfort on the 2nd floor. Instead of feeling that change in temperature going up the stairs, it's not more consistent with the 1st floor. These guys are awesome and I totally trust their work and expertise. Give them a call ASAP, you will not be disappointed.

We bought an older 1957 house recently and discovered that the attic was severally under insulated and not air-sealed at all.
Koala was amazing and Lewis and team were excellent. Their attention to detail showed in their air sealing and they blew in fiberglass insulation and now we have R60 up there!
The owner even called me to inform me that we did not have soffits so he was very honest and took off the rafter vent installation saving us some money!
Koala does fantastic work at a fair price and the owner takes pride in his team. They did great work and cleaned up very well after they left.
I would recommend Koala to anyone looking to raise their insulation value or replace some old insulation in their house!
