Lifespan of 80 years or more. Closed-cell foam bonds to the substrate and stays there. It does not compress, sag, or degrade under normal conditions. The air seal you start with is the one you keep.
Open-cell holds up in conditioned spaces. Open-cell foam is softer but equally durable in attics and walls that stay within your home's thermal envelope. Keep it out of persistently wet areas like unconditioned crawl spaces.
Safe for occupants once cured. There is a brief window after spraying when off-gassing occurs and the home needs to be empty. After 24 hours of ventilation, the foam is chemically inert and fully safe for everyone inside.
No settling or gaps over time. Unlike blown-in or batt insulation, spray foam does not shift. It holds its shape and coverage for decades without needing top-ups or replacement.
Resistant to pests and moisture. Closed-cell foam has no food value for rodents and slows moisture migration through walls and roof assemblies, a real advantage in Gulf Coast construction where humidity is the enemy.
Backed by manufacturer warranties. Major foam systems carry lifetime building warranties when applied to spec by a trained installer. Ask to see the product data sheet before work begins.
