"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."

"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

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.

Whether you should remove old insulation before blowing in new insulation depends on your particular situation. Fiberglass insulation attracts insects and mold over time, so if it has been decades since your last insulation upgrade, consider removing the old materials before placing the new ones. However, most types resist mold, insects, and mildew, so once you get the go-ahead from your contractor that your space is free from all three, feel free to install the new insulation directly on top of the pre-existing materials.

Heavily exceeding building code requirements for insulation not only wastes money on materials but can also lead to ventilation and moisture problems. In most cases, the minimum amount of insulation required by code is perfectly adequate.

The primary downside of radiant barriers is their limited effectiveness in cold climates. They are designed to reflect radiant heat, making them less beneficial in cooler conditions where heat retention is more important. 

Radiant barriers require proper installation to maximize effectiveness. Incorrect placement can lead to minimal benefits. They also do not provide insulation, meaning they should be used in conjunction with traditional insulation for optimal energy efficiency. 

Yes, many professionals offer insulation options, such as insulated siding (including insulated metal siding), to improve your home's energy efficiency.
