Owens Corning Flame Spread 25 Fiberglas Insulation is a preformed, flexible blanket insulation designed for dependable thermal control in walls, floors, and ceilings. It is produced in R-values from 11 to 38, at thickness from 3.5 to 12 inches, and is available with either a FSK (foil-scrim-kraft) or PSK (poly-scrim-kraft) facing; both of which act as vapor retarders and provide a neat, finished appearance.
