  • Batten bar for single ply membrane used on roofs
    Patent number: 4718211
    Abstract: The present invention provides a batten bar of plastic, corrosion-resistant, material which has thick side portions that resist curling, kinking, looping and distorting of that bar, even when the fasteners that are used to secure that bar and the underlying membrane to a roof are overdriven. That batten bar has a connecting or bridging portion between the thick side portions thereof; and the upper surface of that bridging portion is displaced below the upper surfaces of the thick side portions to form an elongated groove which is at least as deep as the head of a fastener which is used to secure that bar and the underlying membrane to a roof.
