"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."

"Stendahl Exteriors was very knowledgeable about the insulation problem/getting a new roof and new siding. They were able to complete the work in a very timely manner.  We weren't planning on the insulation being done but they were very helpful and courteous in helping us fix this."

Insulation FAQs, answered by experts

Opting for insulated ducts can lead to significant long-term savings on your energy bills and contribute to a more efficient HVAC system. The precise amount you can save depends on various factors, including your climate, usage patterns, and the insulation's quality. However, on average, insulated ducts can result in savings of up to 20% on your annual heating and cooling costs, according to ENERGY STAR®.

Yes, many professionals offer insulation options, such as insulated siding (including insulated metal siding), to improve your home's energy efficiency.

Vapor barriers in attics are a bit outdated and most areas no longer recommend them for attic spaces. For vented attics, the best method is usually to install drywall and cover it with latex paint before attaching insulation fiberglass, cellulose, or foam insulation. When renovating an attic to use as a living space, a contractor can guide you on the best way to cover insulation.

It is usually possible to install insulation yourself, but it’s often better to hire an insulation professional. An experienced insulation pro can determine which type of insulation is best for your space and the R-value get the most value and comfort in your home. Certain types of insulation can cause skin, eye, and lung irritation, and a professional will have the equipment necessary to keep themselves safe and limit the effect on your indoor air quality after the installation. Certain types of insulation—like blown-in and loose-fill insulation—demand a professional for proper functionality and safe installation.

Unfaced wall insulation is easier to cut and install, making it the better choice for a DIY project. It’s also more affordable. But if it’s unfaced, you’ll likely need to add a vapor barrier to reach your desired R-value and efficiency, as it doesn’t offer any moisture barrier.

Faced insulation uses paper or foil to create a built-in barrier and doesn’t require an extra step. It’s also more fire-resistant and safe. But it’s quite a bit more expensive and a little bit harder to work with as a DIYer.
