"Brad and his team did a superb job installing spray foam insulation in our home in southern NH. Brad has a great understanding of how buildings work. The foam his team installed made our home incredibly and immediately warmer for a very fair price. He was upfront and very well reasoned about what would and would NOT work for our ice dams and cathedral ceilings.. His company scheduled us and completed the job faster than all the other contractors offered to do. He also offered a better price out of four bids. I feel that we really were lucky to have chosen Brad to do the work. We received four bids, some were substantially more expensive. And yet, Brad offered the only solution that made sense to us and that actually WORKED. The install went very fast. 24 hours post installation, we had zero smell. Our home was left as clean as when they started the work. I am extremely impressed."

"Simplified Green Homes did a firewall insulation installation in the ceiling of our garage. They were quick to respond to my initial request. They sent an estimate promptly. Getting the work day scheduled took a bit of back and forth but once we established a date they were here and got the job done. Everyone we dealt with was polite and professional. I would definitely recommend this company ."

"This was our first time using Apollo Insulation and Geremy and Dennis did an excellent job removing our old (rodent droppings and urine) insulation. They disinfected and repaired any damage caused by the rodents. New insulation was blown in and we couldnâ t be happier. From the initial inspection and quote Geremy was on top of keeping us informed on what would be done to complete the job. Apollo Insulation cleaned up behind them inside and outside leaving our home with no mess. The price was very reasonable and we were very pleased and satisfied with the quality of the work. I highly recommend Apollo Insulation for any of your insulation needs. Very hardworking and professional service company. Bill and Anne G Wayne, Maine"

Insulation questions, answered by experts

Mineral wool wraps are the most affordable and effective insulation for crawl space ducts. They are easy to cut, last for a long time, and healthier for humans. Meanwhile, fiberglass wraps are cheaper but more hazardous and difficult to handle. If you do choose to use a fiberglass wrap, make sure you are wearing long sleeves and wear proper protective gear.

It is possible to insulate your walls without removing drywall, but it’s not a good idea to attempt the work yourself. A professional can use blown-in insulation or spray foam insulation to fill wall voids without opening up the walls, and the option they use typically depends on your climate and whether or not there’s insulation in your wall already that can remain in place. Spray foam insulation costs more and isn’t always a viable option, but it’s a better insulator. Call in an expert to help decide which is right for you.

Insulation is professionally installed by measuring spaces, cutting materials to fit correctly, and placing them without gaps for optimal thermal resistance.

When it comes to fiberglass insulation versus foam board, there are a few notable differences, both aesthetically and functionally. Fiberglass insulation is soft and flexible, meaning it can be squeezed into tight spaces more easily than foam board. Fiberglass insulation also has a higher R-value, making it a better pick for colder climates. However, foam board insulation can resist moisture and pest damage much better than fiberglass.

Installing sheets of plywood over attic insulation is a popular choice, especially in storage spaces. That said, insulation works by trapping hot air—so it needs extra space to expand and be effective, or you might reduce the energy efficiency of your home. 

It’s important that you never compress the insulation by installing flooring directly on top of it. In many houses, you’ll need to install a subfloor before putting plywood over insulation in your attic.
