        "text": "Retrofit insulation costs depend heavily on the workshop size, ceiling height, choice of material, and accessibility. Spray foam generally carries a higher upfront material and labor investment due to specialized mobile equipment and chemical requirements, but it combines insulation, air sealing, and vapor control into a single pass. Batts and rigid boards feature lower raw material costs, but labor increases substantially because crews must cut, fit, tape, and strap pieces around structural framing, cross-bracing, and electrical lines. Clearing access equipment like scissor lifts into tight bays also influences total project estimates.",
