        "text": "Fiberglass blanket insulation with a reinforced vapor retarder is the standard choice for pre-engineered steel buildings, though rigid board and spray foam are also common alternatives. A major practical tradeoff comes down to cost versus thermal performance. Traditional fiberglass rolls draped over purlins during frame erection are the most budget-friendly option. However, rigid foam or spray foam provides continuous thermal breaks and better air sealing at framing joints, which prevents condensation issues inside conditioned workshops or commercial storage structures.",
