Owens Corning Flame Spread 25 Fiberglas Insulation is a preformed, flexible blanket insulation. It is produced in R-values from 11 to 38, at thickness from 3.5 to 12 inches. It 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.
