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.

They were very respectful of our home and left the premises very clean each day.

Koala Insulation of Central Connecticut provided us with attic insulation removal, air sealing, and installation of new cellulose insulation and an insulated hatch. The company is well organized. The owners and staff were very responsive. They examined the site, provided clear information with their estimate, and responded to a multitude of questions prior to being selected for the job. Once selected, the job was scheduled and fully executed in a very timely manner. The crew was knowledgeable, professional, and personable. They were very respectful of our home and left the premises very clean each day. The insulation is now doing its job quite well! When additional information was requested after the job was completed and paid for, the owners responded immediately. We were impressed from the start and were most pleased with the entire process. We highly recommend Koala Insulation of Central Connecticut to others who are looking to insulate their home.

I use Graeme and Koala Insulation to install some insulation in my attic. They were prompt and on time, did what they said they were going to do and did a great job. Their clean up after the fact was better than my housekeeper has ever done. I will use them again and definitely recommend them.

East Hampton

First rate work from a top notch company.

I highly recommend Koala Insulation. From start to finish their work was excellent. They were friendly when I called to request they come out to give me an idea of what it would cost to insulate our attic. Their estimate was thorough and emailed out to me right away. Questions were responded to quickly and completely. On the day of the insulation installation, their crew showed up on time, they were polite, professional, and their quality work was done with great care and attention to detail. Upon completion, Koala took the time to inspect and review their work with me and they cleaned up beautifully before heading out. First rate work from a top notch company."

On time, respectful, and great service!

East Hampton

The price was reasonable also just another plus for this wonderful company.

Koala Insulation did the walls of my old house badly needing it. They came on time and actually were able to remove the aluminum siding so we could access the walls for insulation, something many others installers would not do. Not only did Angel and Larry do a great job, the siding was put back on and is perfect!! The price was reasonable also just another plus for this wonderful company. I wish them much success in CT.
