This is an Owens Corning kraft-faced fiberglass insulation roll rated R19, sized 23 ft. by 39 ft. for 75 sq. ft. of coverage. R19 suits 2x6 exterior walls, floors over crawl spaces and some attic applications. The kraft facing gives it a built-in vapor retarder, so it goes up faster than unfaced batts plus a separate barrier. Compared with lower-R batts it fills a deeper cavity, but it is not a substitute for blown-in attic insulation at higher R values.
