4. After the first panel has been secured, the next panel can be installed. Attention needs to be given to correctly endlap the GrandBeam panel. The hem of the panel being installed needs to be placed over the edge of the previously installed panel's anti - siphon channel (Detail A). The panel lap will be secured using a #12 -14 x 3 /" stitch screw with sealing washer at each rafter location (Page 10 — Fastener Location). After determining that the panel being installed is square, a single #12- 14x1" HWH SDST screw should be placed in each panel flat, directly before the rise in the panel rib (Detail A). Be sure that all fasteners are going into the rafters. Fasteners should be placed at every rafter /support location. Repeat this step for all remaining panels with the exception of the final panel installation. 5. The installation of the final panel (the panel closest to the ridge), can be accomplished using two different methods based on the building width and roof pitch. Method 1: Install the final panel following the same procedure as that of the previously installed panels. If the top of the panel extends beyond the ridge area, trim excess before securing the panel. Method 2: In some cases trimming of the final panel can be avoided by shifting the final panel down, creating an overlap of one full rib (Detail D). Fasten the panel using the same steps as that of the standard panel overlap. 6. With all of the panels securely in place, the J or gable trim can be installed to finish off the edges of the GrandBeam panel's at the gable ends. This trim should fastened into each rib of the GrandBeam panel using #14 -14 x1" type A stitch screw with sealing washer (Detail B). 7. After all panels and trim have been installed, the ridge cap can be fastened in place. The ridge cap is installed using #14 -14 x 1" type A stitch screws, every 12" o/c on both sides of the ridge. The fasteners should pass through the ridge cap and into the 6
