The Grip-Deck TubeSeal™ from TRUFAST Walls is designed to help seal blind fastener penetrations of your WRB and air-barrier when mechanically attaching lath over continuous insulation and the WRB. The Grip-Deck TubeSeal™ fasteners with Thermal-Grip® washers enable sealing of the WRB or air-barrier sandwiched between the substrate and the layer of continuous insulation.
