Spray foam insulation is a material applied as a liquid that expands into a solid foam, creating an air and moisture barrier. It is commonly used in walls, attics, crawl spaces, and ceilings to improve energy efficiency.
Spray foam has a higher R-value per inch than fiberglass or cellulose, meaning it provides better thermal resistance. It also creates an air seal, which traditional materials often can’t achieve, helping reduce drafts and improve indoor comfort.
There are two main types: open-cell and closed-cell spray foam. Open-cell is lighter, more flexible, and has soundproofing qualities. Closed-cell is denser, moisture-resistant, and offers a higher R-value per inch.
It can be used in attics, walls, crawl spaces, rim joists, basements, and around HVAC ducts or plumbing. It is suitable for both new construction and existing homes.
Spray foam insulation typically lasts the lifetime of the structure it is applied to. It does not sag or settle over time, maintaining its effectiveness for decades.
Once cured, spray foam is inert and safe for residential use. During installation, proper ventilation and protective equipment are required due to chemical off-gassing.
Most residential projects can be completed in one to two days, depending on the size of the area and complexity of the work.
Yes. By creating a tight seal and reducing air leaks, spray foam can significantly lower heating and cooling costs over time.
Open-cell spray foam provides good sound dampening qualities, making it effective for reducing noise transfer between rooms or from outside.
Yes, spray foam can be retrofitted into existing walls, although it may require removing drywall or drilling small holes to inject the foam.
Costs vary based on the size of the area, type of foam, and accessibility, but it typically ranges from $1.50 to $4.00 per square foot installed.
Closed-cell foam typically has an R-value of about 6.0 to 7.0 per inch, while open-cell foam is around 3.5 to 4.0 per inch.
Yes. Closed-cell foam acts as a vapor barrier and helps prevent condensation, reducing the risk of mold and mildew.
In most cases, occupants are advised to leave the home during application and for 24 hours afterward to allow the foam to fully cure and off-gas.
Many spray foams are made with eco-friendly blowing agents and reduce energy consumption, contributing to a lower carbon footprint.
Spray foam insulation requires little to no maintenance once installed. It’s durable and resistant to pests, water, and decay.
Yes, but removal is labor-intensive and typically requires cutting out the material. It should be done by a professional.
