Give your home an upgrade with blown in cellulose or fiberglass attic insulation and experience savings, good health, and home value!

Blown-in insulation fills every nook and cranny of the attic and creates an extra fluffy layer of effective insulation. It is a convenient choice that can be blown in over existing insulation or in between walls and ceiling joists without disturbing structures. Loose-fill fiberglass or cellulose can be blown on your attic floor, between walls, or other spaces that may require insulation. Blown-in insulation can easily cover large areas and will fill in areas with tight spaces and angles. Koala Insulation of Southeast Denver installs blown-in for retrofit, residential, commercial, and new build construction.

We have 3 convienant ways for you to get in touch

When it comes to blown-in insulation, you have two primary choices: Cellulose and Fiberglass. Learn more with our videos below!

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.

Energy-efficient

Increasing the R-value of your insulation may help you to money on energy bills and maximize the energy efficiency of your home. Blown-in insulation is a environmentally conscious, cost effective way to increase your attic’s insulation, which in turn may help lower your cooling and heating bills. For maximum energy efficiency, we recommend a powerful combination of insulation and proper air sealing. This can help eliminate air leaks that pass through recessed light fixtures, plumbing areas, and duct work.

Blown-in insulation slows heat transfer from your attic to the lower levels of your home during the hot summer and works hard to keep the warm air inside your home during the cold winter months. The attic is the main location where heat enters and exits the home, making it difficult to keep your home temperatures consistent. Proper insulation can target reducing heat transfer while also allowing your HVAC system to increase its performance.

Environmentally Friendly

One of the many positive benefits Blown-in insulation has is that it is environmentally friendly. Not only does it improve the energy efficiency of your home, but it also helps protect the environment.

Cellulose is made up of 80% recycled materials, with the remaining consisting of non-toxic borate solution. This solution gives the insulation a Class-1 fire safety rating and makes it mold and pest resistant. Certain fiberglass products can contain up to 80% recycled glass products and is non-combustible.

Blown-in insulation not only protects your home from energy loss, butal so helps reduce emissions associated with heating and cooling equipment. For those home owners who are looking for economical ways to reduce their environmental impact, curb energy waste, and increase the comfort of your home, blown-in insulation may be the solution for you!

Blown-in insulation provides a dense, effective barrier against heating/cooling loss or gain, and it provides an affordable R-value per inch. “R” means resistance to heat flow. The higher the R-value, the greater the insulating power.

Dense-packed cellulose or fiberglass insulation blocks the bulk of air movement and has a higher R-value per inch than insulation installed at a lower density. Attics can accommodate a deep layer of insulation, as much as 16 to 26 inches, making the resistance to heat flow even higher by installing blown-in insulation.

Fiberglass blown-in insulation is a loose material which allows the installation amount to be customized according to your local energy efficiency recommendations. Depending on which climate zone you live in, you may need a higher R-value. The higher the R-value, the more it will decrease air flow and help you conserve energy.

When it comes to insulating your home, R-value matters.

Solar Power Attic Fan

I spoke to three companies. Jacob at Koala gave me the most informed recommendations for keeping my house cooler. I’m already saving money!!! The installers who blew in insulation were professional, friendly, and clean. My house was left immaculate. I also installed an attic venting fan. The installation process was perfect. Again it was professional and immaculate. I highly recommend this company.

Free Estimate

They were honest about us actually not needing insulation which was both a huge relief and confirmation that this business is reputable and actually cares about their customers. Especially as I had two other bids who came afterwards and they tried to sell us over $1000 in insulation that was not needed. If and when we do need insulation, this company has earned our respect and would absolutely earn our business.

Blow in insulation

I just had Koala come and spray-in insulation in an upstairs bedroom and could not be more pleased with the whole process. Everything from the quote to the actual install was communicated to me in a timely and concise manner. No hidden fees or upsells, just exactly what I asked for. On the day of the install, the two techs were extremely professional and cognizant of the fact that my wife and I were working from home. After they completed their job, they left the room just as clean as before they started. On top of all this, they beat out several other insulation installers by quite a bit. I would definitely use again and recommend Koala!

Living Area Ceiling & Garage ceiling - Blown-In Insulation - Fiberglas

Jacob was great to work with. He communicated well and stuck to his word throughout the entire project. He explained the process and their product. I was quoted a good price and he still made adjustments after they had completed the work due to unexpected work that did not need to get done in a specific section after all (Not their fault). He and his guys were on time the day of the job and got done on a timely manner while not rushing. Once done, they were really good about cleaning off and clearing the path to my furnace which is in the attic where the insulation took place. Any additional mess in the main living space was also cleaned up which I appreciated. I would recommend Koala if you're looking for a reliable company for a fair price.
