                    Flexible, fibrous thermal insulation of glass or mineral wool, made in various thicknesses and lengths and in 16-inch (406 mm) or 24-inch (610 mm) widths to fit between studs, joists, and rafters in light wood frame construction, sometimes faced with a vapor retarder or kraft paper, metal foil, or plastic sheet. Batt insulation is also as a component in sound insulating construction. Also called blanket insulation. (Ching, 1995)
