Apply panels and associated items for neat and weathertight enclosure. Avoid "panel creep" or application not tree to line.. 2.Locate and space exposed fasteners in tree vertical and horizontal alignment. 3. Provide sealant tape at lapped joints of roof panels and between panels and protruding equipment, vents, and accessories. 4. Apply a continuous ribbon of sealant tape to weather-side surface of fastenings on end laps, and on side laps of nesting-type panels. 5. At panel splices, nest panels with minimum 6-inch (150-mm) end lap, sealed with butyl sealant and fastened together by interlocking clamping plates. 3.5 WALL PANEL INSTALLATION A. General: Provide panels full height of building when possible. Install panels perpendicular to girts. 1. Arrange and nest side-lap joints so prevailing winds blow over, not into, lapped joints. Install panels with vertical edges plumb. Lap ribbed or fluted sheets one full rib corruga- tion. Apply panels and associated items for neat and weathertight enclosure. Avoid "panel creep" or application not true to line. 2. Unless otherwise indicated, begin panel installation at corners with center of rib lined up with line of framing. 3. Field cutting by torch is not permitted. 4. Align bottom of wall panels and fasten with blind rivets, bolts, or self-tapping screws. 5. Fasten flashing and trim around openings and similar elements with self-tapping screws. 6. When two rows of panels are required, lap panels 4 inches (100 mm) minimum. Locate panel splices over structural supports. 7. When building height requires two rows of panels at gable ends, align lap of gable panels over wall panels at cave height. 8. Install screw fasteners with power tools having controlled torque adjusted to compress neoprene washer tightly without damage to washer, screw threads, or panels. Install screws in predrilled holes. 9. Provide weather-resistant escutcheons for pipe and conduit penetrating exterior walls. 10. Flash and seal wall panels with weather closures under eaves and rakes, along lower panel edges, and at perimeter of all openings. 11.
