        "text": "Open-cell and closed-cell spray foam are two distinct types of insulation. Open-cell foam is softer and more flexible, with a lower R-value per inch, and primarily functions as an air barrier. It's often more affordable and can allow moisture to pass through. Closed-cell foam is denser, more rigid, and has a higher R-value per inch, acting as both an air and vapor barrier. It also adds structural integrity to walls. The choice depends on specific needs for R-value, moisture control, and structural support.",
