"So happy I went with USA Insulation. After learning about foam insulation, I knew it was the right option for my house. They insulated my walls and attic in a day and a half, and I could feel the difference right away."

"We recently worked with Evergreen Foam & Insulation on a new construction project where they applied spray foam insulation to the walls and roof deck. Their team was professional, efficient, and maintained clear communication throughout the process. The quality of their work met our expectations, and they completed the job on schedule without any issues. The attention to detail during application was excellent, and the site was left clean and ready for the next phase of construction. We’re pleased with the results and look forward to working with Evergreen Foam & Insulation on future projects."

"Charles was awesome all around!! Came out for an inspection, advised me of issues and the route I should take. We followed through and couldn’t be happier with the results, and how easy the process was. We got a full encapsulation with a dehumidifier and the difference in the air is amazing. Highly recommend if you are thinking about getting your crawlspace encapsulated!"

Insulation questions, answered by experts

Closed-cell spray foam insulation itself serves as a vapor barrier (or vapor retarder). However, you may need to install a vapor barrier if you have open-cell spray foam insulation. When in doubt, work with a professional insulation contractor, as they can provide more detail about the specific needs of your home in your climate.

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.

Most insulation lasts 15 to 20 years, but it really depends on the type of insulation. Spray foam is a permanent insulation material that can last up to 100 years. Fiberglass and cellulose typically settle, shift, or deteriorate around 15 years. Once your insulation reaches the 15-year mark, it's time to check it for signs of needing to be replaced.

The R-value is a rating that measures an insulation's thermal resistance—in other words, how well it insulates. A higher R-value provides more protection for your pipes, and all pipe insulation materials should have an R-value listed on the product description or label. Each insulation type has its own R-value, which typically falls between one and five for most pipe insulation. When making a selection, Energy.gov recommends choosing a pipe wrap that is at least one inch thick, and the International Code Council (ICC) suggests choosing a material with an R-value of at least 3.

When temperatures are too cold, it can keep ice from melting, and products like ice melt and rock salt are ineffective. Water turns to ice in temperatures below 32 degrees Fahrenheit. Ice melts on its own when temperatures reach above 32 degrees Fahrenheit. 

Ice melt loses effectiveness in temperatures below -25 degrees Fahrenheit, and rock salt works in temperatures 5 degrees Fahrenheit and warmer.
