"Travis, Logan and Jaxon were very professional in their work and cleaned up after. Great group of men to work with and I highly recommend Koala. Also had a room fan installed. None other of the estimates I had offered a fan. Another feature Koala offered and installed was an insulated zipped hatch cover over the entrance cover into the attic to completely seal any air leakage. Highly recommend Koala"

"They had a great group of people to work with, The crew was there at the appointment time. Nick and his team worked together well to get the job done, including adding insulation to the attic, adding foam to all exterior walls, and insulating in the basement. This was all done in 1 day and they cleaned up after themselves. I would highly recommend them."

Insulation FAQs, answered by experts

Whether you should remove old insulation before blowing in new insulation depends on your particular situation. Fiberglass insulation attracts insects and mold over time, so if it has been decades since your last insulation upgrade, consider removing the old materials before placing the new ones. However, most types resist mold, insects, and mildew, so once you get the go-ahead from your contractor that your space is free from all three, feel free to install the new insulation directly on top of the pre-existing materials.

Asbestos has many beneficial properties, including fire resistance, strength, and chemical resistance. It is also an excellent insulator, which is why it was used in pipe insulation and other building materials for decades. For all its benefits, asbestos is dangerous for human health, which is why it was eventually banned from use in certain products.

The level of insulation is determined by both the material and the thickness of the door. Some garage door materials (such as wood) have natural insulating capabilities, while other materials (such as metal) do not. No matter the material, two-layer and three-layer garage doors have a higher R-value than single-layer garage doors, as insulation is fitted between the panels. 

Yes, you can use too much bubble wrap. If you overdo it with the wrapping, it can strain the top of your box and break open the taped seal, risking the chance that the contents of the box could fall out or break. Use enough wrapping to fully cover your item without compromising the security of your box.

Insulating a detached garage won't reduce your home's heating or cooling bills—and insulating an attached garage will only have a small effect on your home's energy efficiency. However, insulating an attached garage can reduce the transfer of heating and cooling to and from the outdoors, which can reduce the amount of energy your home needs to stay comfortable. Also, having an insulated garage is just more pleasant. Balance the cost of insulating your garage with how you'll use the space to determine if the project is worth it.
