Sol Foam Insulation, LLC is a member of Sol Enterprises. Since 2003 we have been family owned and operated. Our Foam Insulation division is a highly experienced team equipped with state of the art chemicals and tools to get the job done correctly. We apply Closed Cell Spray Foam into open-wall cavities, crawl spaces, perimeter joists (any exposed rim or band joist), and cathedral/sloped ceilings at an industry leading heat resistance rating of R-7 per inch of thickness. While the product must be installed to local code, the amount of application varies. Our Closed Cell Foam, when applied correctly, creates a vapor barrier, prevents air infiltration and exfiltration, and fully cures to the touch within 15 seconds. Our closed cell foam also adds 75-200% racking strength to your walls!

"Extremely happy! Would absolutely recommend this company and product to my family and friends."

Insulation questions, answered by experts

DIY installation is not recommended, as professionals ensure even distribution, proper sealing, and compliance with building codes.

The best way to reduce heat upstairs is to release it by opening a window. Hot air rises, and if you can create some airflow by opening a window upstairs and also one on a lower level, the hot air should be pushed out of the home. Remember that fans pointing out the window do a much better job of circulating air than fans pointing into the home.

Expect your home insulation project to take between five and 12 hours to complete on average for batts or boards and two to five hours for spray foam or blown-in insulation. It might take longer if you need to remove your home’s existing insulation, you have a higher-than-average square footage, or accessibility is limited.

In most cases, the building code in your location will determine the minimum amount, in R-value, required for your home's walls, attic, and other spaces. For attics, the minimum R-value amounts start at R30 in the south, R38 in mild climate locations, and R49 in northern states and cold western areas.

2x4 walls can hold R-13 or R-15 batts of insulation, which is usually about 3.5 inches thick. You should also check with your local building codes to see if there’s a required thickness you need to adhere to. 

You can also use R-value maps to determine the best thickness and ratings for where you live. For example, someone in Texas doesn’t need as thick of insulation as someone in Montana. Energy Star has a good one you can reference.
