Blanket insulation is often accustomed to insulate roofs of pre-engineered metallic structures. Fiberglass insulation is the most common batt/blanket insulation, and it is also offered as a blown-in solution. Mineral wool is additionally obtainable in configurations well suited for roofing; it has a better compressive energy than fiberglass. Cellulose (recycled newsprint) can be a standard blown-in insulation. If cellulose is specified, specify an item that's been treated for mould and fire resistance.
