        "text": "Spray foam provides seamless air sealing and acts as its own vapor barrier, while fiberglass blankets cost significantly less and install faster during initial building erection. Closed-cell spray foam seals irregular gaps, prevents drafts, and adds subtle rigidity to metal skin panels, but it is a permanent application that can make future exterior panel replacement difficult. Fiberglass blanket systems retain flexibility for panel repairs and remain easy to modify if structural changes are made later.",
