"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!"

"I only needed part of my attic insulated and brought up to code. I had others try to sell me lots of services I didnâ t need, nor ask for. Denver Insulation came out, measured the area, and gave me a straight forward quote. Work was very fast and professional."

"I was very pleased with the pricing structure (I compared to 2 other quotes). Jason Montgomery also helped me with an issue in another part of the house at no cost. Thanks. My only request would be a picture of completed work (even from his phone) showing the depth of insulation since I don't climb ladders to attic."

Insulation questions, answered by experts

Regular inspections for moisture damage, pest infestations, and proper R-value performance help maintain efficiency.

A vapor barrier keeps moisture out of the crawl space, while insulation reduces the amount of unconditioned air—and sometimes moisture—that enters the space. Coupling a vapor barrier with insulation can help prevent humidity and related moisture damage in a crawl space while also making your home more energy-efficient. Just be sure to use insulation that won’t get damaged from moisture, like rigid foam board or expanding spray foam insulation.

Mineral wool has an excellent life expectancy of up to 50 years, provided it's kept dry and free of pests. Compared to fiberglass, with a life span of 20 to 30 years, mineral wool stacks up well for long-term cost savings. Sheep wool maintains a similar life span to fiberglass, while estimates for hemp wool insulation life expectancies are all over the board, ranging anywhere from 20 to 100 years.

For standard 2x4 walls, the ideal insulation has an R-value between R-13 and R-15. This level of insulation, typically around 3.5 inches thick, fits well within the wall cavity. Common options include fiberglass batts and spray foam. The best choice for your home can depend on your climate; use R-value maps, like those from Energy Star, to determine the recommended level for your region. For colder climates, you might also consider adding exterior insulation for greater efficiency. Always check with your local building codes to ensure you meet any required standards.

You can purchase bags of cellulose and loose-fill fiberglass blown-in insulation from the same local home improvement store where you rent your blower. If you want to use rock wool insulation, you may need to special order it.
