"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."

They provided a thorough assessment of my home’s insulation needs and offered clear, honest recommendations without any pressure.

"We contracted Saunders to remove Vermiculite from our attic and thereafter air seal and re-insulate. We were very happy with the work as well as the customer service. Steve came to give us an estimate very promptly and then was able to schedule the work within a couple weeks. He was very informative regarding recommendations for a better energy efficient home, yet did not pressure us into any purchases. Afterwards they even helped us do an Energy audit in order to qualify for Focus on Energy incentives. We couldn't be happier with Saunders Insulation and will definitely call them for future projects!"

"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."

Insulation questions, answered by experts

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.

While fiberglass is dangerous to work with, it’s a perfectly safe material once it’s installed. If you’re tackling the installation yourself, make sure you take the proper safety precautions and wear the right gear to avoid skin and eye irritation and lung complications. Working with a professional insulation company can mitigate these risks.

Plaster itself has a higher R-value than drywall. However, there are other considerations surrounding plaster and insulation. As a general rule, it's easier to obtain consistency in insulating value and quality when working with drywall rather than plaster. Plaster walls often don't contain any insulation behind the wall covering by design, and careful evaluation is necessary when choosing to add it.

Durable materials suited for climate include aluminum for coastal areas or composite wood in varying environments for durability and minimal upkeep.

There are two reasons why cellulose insulation repels rodents (and insects). First, the insulation has been treated with boric acid, which is a natural pest-repellent. In addition, the loose-fill style of cellulose creates less-than-ideal conditions for mice and other rodents to nest and burrow, helping to keep them at bay.
