"Jason and the crew were very professional. After talking with multiple contractors the choice was clear. I was given 3 options for insulation. Reg blown, closed cell on deck with blown, or full blown deck and bottom of the roof. We chose to go with foam bottom and blown on top of it. These guys had nice equipment and were fast and accommodating to schedule. So happy we chose Advanced Insulation Solutions to do the work! Thanks again!"

Customers say: Quick response

"Since we had squirrel damage on some electrical wiring in the attic, we hired them to first remove the old insulation so the electrician could more easily do the wiring repair. Cost more to remove the old stuff (old and worthless), but it saved $500 on the electrical work bill. After the electrical work was done, they came back and filled in the attic with R49. The guys doing the the removal and installation work were great, and it went quickly and efficiently. Terry was a good guy to work with for estimates and scheduling, and Brian for invoicing. Overall, we are very happy. Wish that work with all home contractors went this well."

"It's hard to know about the quality of the work since I wasn't up in the attic with him. Would have been nice to have before and after pictures so I could see the amount of new insulation blown in. I just have to take Jasons' word for it. His cost was about 30% lower than the competition I got bids from. Overall satisfied."

Insulation questions, answered by experts

Yes. Bathroom insulation requires a vapor barrier. As a matter of fact, bathrooms and kitchens are the two areas of the home that should always get a vapor barrier because of the excess moisture. If you don’t have a vapor barrier in place in these rooms, the moisture will build up and eventually lead to mold and bacteria, not to mention the destruction of the insulation.

One of the disadvantages of soffit vents is they can bleed warm air from the attic during winter, resulting in slightly higher energy bills and a colder house. There are ways to mitigate this effect—mostly just closing the vent in the fall. What’s most important is your attic is ventilated to some degree in the winter.

Yes, you need a 1.5-inch to 2-inch air gap in a cathedral ceiling to allow proper air flow and prevent cathedral ceiling venting problems. This amount of airspace allows warm, moist air to properly leave your ceiling to avoid moisture build-up and other issues that put your home at risk. You can also add an air vent for extra air flow.

The best R-value for home insulation depends on where you live and where you’re installing the insulation. Your climate zone plays the biggest role in determining the correct R-value, so be sure to know which zone you live in when determining the R-value you need.

Polyisocyanurate foam, or polyiso for short, has the highest R-value per square inch: 6.5 to 6.8. Polyiso is a rigid foam that comes with a reflective foil on both sides to serve as a radiant barrier. Given its high R-value, rigid foam is usually meant for foundations and basement walls.
