This worksheet narrows the material system to spray foam, so the scope questions change. A proposal should state open-cell or closed-cell chemistry, installed thickness, target R-value, substrate preparation, ventilation during installation, ignition or thermal barrier, trimming, cleanup, and any removal of existing insulation. The default area alone cannot resolve those specification choices.
