An apparatus, method and system of insulating a building such as a poultry barn uses netting structurally of the type to hold sod together. The netting is stapled to the bottom of trusses making up the ceiling of a barn and the attic of the barn. Ceiling material is superimposed below the netting to form a ceiling. Loose insulation, typically fiberglass, is blown onto the netting to be held thereby and to form an insulation layer in the attic of the barn.
