        "text": "Open-cell and closed-cell spray foams differ primarily in their cell structure and density. Open-cell foam is lighter, less dense, and more flexible, allowing moisture to pass through. It's often used for interior walls and attics for sound dampening and insulation. Closed-cell foam is denser, more rigid, and acts as a vapor barrier, preventing moisture and air infiltration. It has a higher R-value per inch and is suitable for exterior walls, crawl spaces, and areas needing structural enhancement.",
