Just had David and his team do blown-in in our house and the service and install was the best. They were neat clean and right away notice a huge difference in our electric bill along with overhead noise from outside from airplanes....so happy with this investment to our home!

The Koala crew did a great job. The insulation job was promptly scheduled and reasonably priced. The additional insulation should reduce my electric bill. My house needed missing insulation to be reinstalled. Jeff, and the crew were professional and super nice to deal with. Thank you so very much.

Great experience! Connor showed up on time for our consultation and he was extremely personable and real knowledgeable about all of the different insulation solutions Koala has available. I thought I would drive him crazy with all my questions, but he was patient and was able to give answers that really made sense. I decided on the spray foam, and I could not be happier with the results. I feel like I live inside a giant Yeti cooler now! I expected the foam to make a difference, but I had no idea just how effective it could be. On top of controlling the temperature, the house is a lot quieter now, which I hadn't considered when I decided to go this route. Don't hesitate to have Connor and his team out to your place. My only regret is not making this decision sooner. Thanks so much guys!

LEARN ABOUT air sealing!

One of the best ways to get the biggest return on your air sealing investment is to combine it with an insulation upgrade! Learn more about types of insulation that we use in our videos below!

Why air sealing is important

Insulation alone is not going to be as effective as with combining it with air sealing. To deliver the optimal improved energy efficiency, air sealing will act as a vapor barrier and stop any air from penetrating into your home.

By sealing all gaps and holes, it creates an air barrier, blocking air from passing through walls and the ceiling into the attic or outside air in filtrating into your home.

A properly sealed home will not only stop air leakage but will also keep water out, keeping your insulation in top condition. It also contributes to increased comfort, improved indoor quality, lower utility bills and controls moisture.

Koala insulation experts offer custom solutions to provide you with the right solutions for your specific needs. We offer air sealing services along with batt, spray foam and blown-in insulation products to guard against heat loss and moisture related problems.

CELLULOSE

Cellulose consists of fibers made from recycled newspaper, cardboard, or wood and is made with or without binders. Cellulose is a very common type of blown-in insulation as it is made from recycled materials and is chemically treated to resist pests, mold, and fire. Boric acid is the primary chemical used to treat Cellulose insulation and is found naturally in seawater, fruits, and plants.

FIBERGLASS

Fiberglass is made from plastic, glass, and other raw materials that are melted and spun into fibers that resemble the texture of wool. Fiberglass insulation has moisture and fire-resistant properties. Because fiberglass is made from sand and glass, it is naturally non-combustible. Fiberglass has significant recycled content with some loose-fill products containing up to 80% recycled glass.

Very happy with Koala Insulation

Very happy with Koala Insulation. Michael took the time to look at both my attics before he presented an estimate. He also took pictures which were very helpful to see how much we really needed new insulation. Great Crew, worked very hard and cleaned up after the work was completed. I would really recommend Koala if you are thinking about insulation."

Wheeling

Found them off Angi

Found them off Angi and from the initial phone call through the completion of the insulation project they were great to work with. We especially appreciated them moving the work date to a day when our kids would be out of the house all day so we didn’t have to worry about the work interfering with their nap schedule. We will recommend Koala to anyone we know that needs this type of work done."

Rolling Meadows

Fantastic company

Fantastic company, arrived on time, explained everything there was to be done. Honestly these guys are really good, I was in my attic the day before they came to get some things out before they blew in new insolation. I was dieing the first few mins up there, they were up there for hours, sealing gaps, adding baffles, and blowing new insolation in. Great company, great employees, great options and prices."

Mt. Prospect

On time, fast working

On time, fast working and I noticed a difference in my house the day after the work was completed. The upstairs was always warm due to lack of insulation in attic. (summer installed) Not any more!"

Glenview

Outstanding duo of Nenny and Ryan

Outstanding duo of Nenny and Ryan installed R-60 fiberglass insulation in my attic in my 1963 ranch home! They were careful, courteous, and explained how they performed the work. They protected the corners of rooms, hallways and doors from the hose that delivered the new insulation. They cleaned everything and left the house clean and tidy! I highly recommend Koala for this type of work!!"

Park Ridge

Michael and Koala were easy to work with from start to finish

Michael and Koala were easy to work with from start to finish. Michael explained what was needed and how the process would work. He provided 3 separate quotes for the different areas of my house, and I felt he gave an honest recommendation of what I should prioritize. Michaels team, led by Nenny, showed up on time, were efficient, and respectful of my house."

Deerfield

We had a wonderful experience

We had a wonderful experience from start to finish with this team! Michael met with us for our initial consultation. He was knowledgeable and explained the entire process step-by-step. He was also extremely considerate of our home and made sure to keep everything clean and neat. The installation team was led by Nenny who arrived on time, was thoughtful about keeping our home clean, fully explained each step as it was executed, and finished in a timely fashion. Nenny was assisted by Ryan who was friendly, kind, and thoughtful as well. We would highly recommend their work to anyone looking to improve the insulation in their home!"
