"The whole team exudes professionalism and good-will. Marc was very transparent with their very competitive pricing, and always looked to provide the most relevant information to me as the home owner, rather than up-selling me like countless others have done. The techs were extremely quick and thorough, always kept me updated on the decisions they made, and went out of their way to make sure everything was above and beyond. Overall, I'm extremely pleased with the service and will go to Affordable Insulation for any other future endeavors."

"Bottom line: I would hire this company again. Koala Insulation came and inspected my attic spaces with a infrared scanning tool. They looked at the level of insulation and found areas where the heat was penetrating more. They recommended specific actions and gave me a number of quoted options on the spot. I was then able to book the service within days of the initial visit. The technicians came and performed the service professionally and made sure to involve me where needed. I would hire them again."

Insulation questions, answered by experts

The best type of attic insulation depends on where you live, your budget, and what stage of construction the attic is in. For example, if you're building a house, then structural insulated panels are a worthy investment since they're easy to install during construction and they're the most energy-efficient type of insulation.  

Additionally, if you live in a very warm climate, then you can potentially save quite a bit of money by opting for reflective insulation, which is more affordable than comprehensive insulation but doesn't work well for cool climates. Blown-in, loose-fill, and spray foam insulation are all great options for attics in moderate climates.

Structural insulated panels and rigid foam boards have the highest R-value of any insulation that contractors commonly use, with R-values reaching up to around 8.0. These types of insulation are best in extremely cold climates, but they’re generally preferred for new construction, as they can be challenging to retrofit. Blown-in and loose fill insulation provide the next best insulative value, provided the installation is done properly. It’s important to choose an insulation type that meets your needs based on climate, as maximizing R-value may not always be financially worthwhile if you live in a moderate climate.

In addition to adding insulation to your attic, you may want to add a radiant barrier. A radiant barrier works by using reflective material, such as foil, on the attic floor. As heat penetrates the roof and enters the attic, the radiant barrier reflects the heat upward and back through the roof. If you receive a lot of direct sunlight on the roof, using both a radiant barrier and insulation in your attic can provide significant benefits.

Air duct insulation typically lasts for 10 to 15 years or even longer, depending on the material and maintenance. It's important to conduct periodic inspections to check for signs of deterioration, such as water damage, tears, or general wear. If you find any of these issues, it may be time for repairs or a full replacement. You might also consider upgrading your insulation even if it's in good shape to improve your home's energy efficiency and enhance your HVAC system's performance with newer, more effective materials.

Minimal but regular checks can ensure maximum thermal performance.
