The present invention relates to a fire retardant binding tape. The binding tape is employed to affix the butt splice joint (or overlapping joint) between rolls of fire retardant material, where one roll ends and another begins. Should the binder tape be subject to elevated temperatures, it will shrink toward the joint seam, thus strengthening the seam, and form a char that minimizes heat input to the flammable materials (foam) located beneath the fire retardant barrier material. The nonwoven binding tape has fire retardant cellulosic fibers, a low melt binder, and an adhesive on one side used to affix the binding tape to the edge butted pieces of a flame retardant barrier material. Instead of the low melt binder, the fibers may be mechanically secured. Optionally a carrier film layer may be used to make the tape more rigid.
