"The gentlemen from Superior Insulation discovered a missing piece of duct work that was causing air from the cold air return of our geothermal heating unit to be pulling air from the unconditioned attic space above our second floor bedrooms.  My husband installed the duct work.
They put blown in insulation above our family room, above our second floor bedrooms and on top of duct work inside knee walls running the length of the house and also did spray foam insulation around some small doors into knee walls.
The work done by Superior Insulation decreased our energy usage by 40%.
We would recommend Superior Insulation to anyone.

"I cannot recommend barrier spray foam enough. We had been looking for a company that I felt comfortable doing our spray foam insulation in the completely un-insulated attic space for a few weeks before I found Robert Keeney from barrier spray foam and I am extremely glad that I was able to find them because I could not be more pleased with the service and the quality of the work that they produced. Robert was incredibly efficient, showed up exactly when he said he would to do a free estimate, he was very good at explaining the R values and the percentage that they would actually insulate the space and what his recommendations are and for that I am extremely grateful. The other companies that we had to quote did not go into this level of detail! Barrier spray foam helped me to feel very comfortable that they were doing everything they could to make sure that the work that was done was what the space needed, and the quality was top notch. We received their very reasonable quote exactly when he told me I would, and not once did I feel that communication was lacking. We were scheduled quickly and on the morning of the assigned day Robert and his crew showed up promptly, they had everything they needed to start work very quickly, they all wore masks and were very respectful of our space and putting down tarps to cover everywhere that they walked. They started promptly, explained what they were doing, explained where they were throughout the process and let us know when they were ready to leave. They were in around 8:00 AM and left around 2:00 PM, their work is incredibly neat and we can't find a single fault with it! Thank you so much Robert and team from Barrier spray foam!"

Insulation FAQs, answered by experts

Yes, eco-friendly blown-in insulation options include materials made from recycled cellulose or wool. These offer excellent thermal performance and sustainability, reducing energy consumption and environmental impact while enhancing home efficiency.

A garage ceiling needs a vapor barrier if it’s a heated garage or if you’re installing insulation in the ceiling. Without a vapor barrier, you risk moisture issues and mold growth. If you have an unheated garage and don’t plan on installing insulation that could get wet and harbor mold, the ceiling doesn't need a vapor barrier.

Insulating windows without plastic is usually the better method. Outside of simply replacing your windows, you could buy cellular shades, which trap air between the window and the home, add a window film that blocks UV rays and traps heat, or cover your windows with a low-emissivity coating called “low-E.”

The most affordable way to insulate a garage involves choosing cost-effective materials like fiberglass, which comes in batts or rolls and is relatively easy to install. You can often install this type of insulation without needing to add drywall, which helps reduce costs. While a DIY approach might seem cheapest, hiring a professional installer can be highly cost-effective. Experts can accurately determine your garage's specific insulation needs and ensure the best results for your investment, often using batt insulation for the bulk of the project.

Canned spray foam has an R-value of R-3.7 per inch. However, it’s not great for use as insulation. Also known as single-component spray foam, it doesn’t expand as much as two-part types that work for insulating the whole house. Save the canned foam for gaps around doors and windows.
