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

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.

These two types of foams are similar chemically, but they are applied in a much different way and each has its own pros and cons. Spray foam can only be used if the area where you will be installing the installation is wide open and easy to access. Injection foam should be used where it's cost-prohibitive to remove the walls that are placed over the insulation. Spray foam is a much less expensive process and requires less expertise. 

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

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.

Duct insulation typically has a long lifespan, often exceeding 10 to 15 years. However, periodic inspections are crucial to check for signs of damage, wear, or deterioration. If you notice issues such as torn or water-damaged insulation, it may be time for replacement or repairs. Additionally, consider upgrading insulation if you're looking to improve energy efficiency or enhance your HVAC system's performance.
