"I called 5 Insulation companies for estimates in Oct.2025, when we were having other work done to our home & discovered we had No insulation between the studs. USA 🇺🇸 Insulation was the most expensive but they were the most thorough during the sales process, as far as explaining how everything was to be done & showed me photos. They were the ONLY company that offered the blown in expansion Insulation. Which is what made the job a little more costly, but they used the best product because it doesn't settle over time, which to me made it worth it. They came on Dec.15th which was a VERY cold day, with a 4 man crew,each with a specialized task, (Foreman, siding removal, hole driller, foam insertion). They were very professional, answered all my questions, cleaned up my property when done & did a heat camera procedure that showed me how the walls were cold before hand & were already warming by end of job. I highly recommend this company to anyone needing to have this done."

"Owner Kyle Driessen and his team were prompt, courteous, and highly knowledgeable. They provided a thorough assessment of my home’s insulation needs and offered clear, honest recommendations without any pressure. Their expertise in spray foam insulation was particularly impressive, ensuring that every nook and cranny was properly sealed."

"Salesman was very professional. Showed up in a vehicle worth the name on the side and in a uniform. Made a video of the bad area of our gutters and explained in detail what problems this would cause and had a very good presentation about the company and product."

"They did an excellent job the opening to the crawl space had to expanded to allow entry of a man, and Saunders was able to do this. They installed a bathroom fan , so that the fan could be vented to the outdoors instead of into the Attic. Saunders personnel were able to tell me what they saw while down in the crawl space, which included other issues that I will need to resolve in the future, but which I'm glad to be made aware of. Per my brother who is an engineer, Saunders did an excellent job of both lining and insulating the crawl space and insulating the attic. My brother is picky so I can recommend Saunders installation specialist."

Insulation questions, answered by experts

Cellulose insulation is usually made from recycled paper products, such as old newspapers, but cellulose might also contain recycled denim. While most homeowners traditionally buy cellulose insulation to use for installation, it is possible to make your own at home with old newspapers, cardboard, a paper shredder, and boric acid (important for fireproofing your cellulose insulation materials).

If the temperature outside is around 90 or 100 degrees with the sun beating on your home’s roof, it’s common for the attic temperature to reach 150 degrees or more. This excessive heat shows the importance of having a radiant barrier in place along with insulation. The radiant barrier reflects the heat entering the attic back upward, keeping your home’s temperature more consistent.

Yes, guiding choices between open-cell and closed-cell foams based on needs.

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.

You do not need to drywall over most types of garage insulation. However, doing so can increase noise reduction, make the space more attractive, and keep children and pets from touching harmful fiberglass insulation. If you’re using cellulose or some other type of blown-in insulation (fiberglass and mineral wool are common), you will need drywall to contain the insulation material.
