17.9 Panels are to be fastened per the roof panel fastening schedule and calculations noted on the shop drawings. To install fastener, pre-
drill using the correct drill size (see 17.8, above). Prior to placing saddle washer, a bead of butyl caulk should be placed into the pilot
hole. Set the "SW-01" saddle washer in place and insert the fastener through the clip. Apply pressure to connection point by standing
directly on the overlapping hi rib panel to ensure that the joinery is fully nested and tighten down until assembly is snug. Use a 600 rpm
electric screw gun to drive fasteners. Do not use impact tools as these devices will over-tighten and cause damage.
17.10 The fastening pattern will depend on the panel thickness, span, substrate, and design loads. Consult your all weather insulated
panels representative or the factory for allowable panel and fastener design loads. If (2) saddle washer assemblies are required, always
put the second saddle washer assembly next to the overlapping hi rib (see figure 9, below).
17.11 Follow SR2 series standing seam electric seamer manual to seam joints to a 90° bend. To prevent the possibility of panels being
blown off the building or wind-damaged, it is highly recommended that seaming be completed as soon as possible. This will ensure that
the roof assembly is adequately secured during installation.
