This detail illustrates the proper fastener locations and patterns for attaching wall panels to the building's structural members.
Member Screw Pattern: Wall panels are secured using 12-14 x 1-1/2" member screws in a 5"/7"/5" on center pattern at specific locations. For both PBR and PBU panels, the screw pattern spans across the panel ribs with 7" spacing at the outer sections and 5" spacing at the center, creating a repeating 12" module. The panels have a 2-1/2" edge distance from the panel side lap to the first fastener.
Location Types:
- Type A (Base, Eave, Rake, and Panel End Laps): Screws are installed at every rib location using the 5"/7"/5" pattern. This increased fastening is required at panel terminations and transitions where greater wind uplift resistance is needed.
- Type B (Intermediate Members): Screws are installed at a reduced pattern at girts between the base and eave, as these locations experience less stress.
Detail "A" - Side Lap Connection: At panel side laps, stitch screws are installed at 20" on center in wall color. These screws connect adjacent panels at the bearing leg (overlapping rib) without penetrating the structural member, creating a weather-tight seam between panels in the sheeting direction.
Section Through Panel End Laps: Where panels overlap vertically, a minimum 3" lap is required. Member screws at 5"/7"/5" on center (12-14 x 1-1/2" in wall color) secure both panel layers to the girt at these lap locations.
Note: All sheeting fasteners will color match to the panel.
