Barrier-Bac Seam Tape

Barrier-Bac seam tape product

Barrier-Bac seam tape

Barrier-Bac XF Seam Tape is a ribbed 28 mil thick tape with a very high adhesive strength to seal all seams. The tough outer layer is a 5 mil multi-ply, textured, cross-laminated membrane manufactured from proprietary polyethylene resin with a long life expectancy underground. The adhesive coating is a 23 mil modified asphalt that offers superior adhesive strength in low temperature.


All seams and/or joints can be jointed by seam tape. All penetrations must be sealed with a Barrier-Bac vapor retarder and seam tape. This ribbed Barrier-Bac XF Seam Tape works perfectly with ribbed Barrier-Bac Vapor Barrier products to form an interlock mechanical bond and tightly block moisture migration from entering through seams.


XF Seam Tape is available in standard roll size of 4" × 150 ft. Nine rolls in one carton. 180 rolls on a pallet.
