ACCESSORIES
Sheet metal flashings, trim, moldings, closure strips, caps, preformed
crickets, equipment curbs, [gutters,] [down spouts,] and other similar
sheet metal accessories provided in conjunction with preformed metal panels
shall be of the same material and finish as panels, except that such items
which will be concealed after installation may be provided without the
finish if they are aluminum or stainless steel. Provide ridge and rib
closures, as specified. Metal shall be of thickness not less than that of
panels. Molded closure strips shall be closed-cell synthetic rubber,
neoprene, or polyvinyl chloride premolded to match configurations of
preformed metal panels. Thermal spacer blocks and other thermal barriers
at concealed fasteners shall be as recommended by the roofing panel
manufacturer.

Closures
2.3.1.1
Ridge Closure
Metal-clad foam or metal closure with foam secondary closure matching panel
configuration for installation on surface of roof panel between panel ribs
at ridge and headwall roof panel flashing conditions and terminations.
Foam material shall not absorb water.
2.3.1.2
Rib Closure
Aluminum, closed-cell or solid-cell synthetic rubber, neoprene or polyvinyl
chloride pre-molded to match configuration of rib opening. Material for
closures shall not absorb water.
2.3.2
Fasteners
**************************************************************************
NOTE: In the high winds, metal will vibrate and
fatigue at fasteners on "normal" spacings. For this
reason, cleated (blind fastened) flashings are not
acceptable, and attachment at 50 to 200 mm 6 to 8
inches on center is customary. Flashing should not
extend a significant distance more than 25 mm one
inch beyond a support or fastener.
**************************************************************************
Series 300 stainless steel with composite metal and neoprene composition
washers. Fasteners for attachment to structural supports and fasteners for
attachment of panels shall be as approved and in accordance with
manufacturer's recommendation. Unless specified otherwise herein,
fasteners shall be either self-tapping screws, bolts and nuts, or
self-locking bolts. Design fastening system to withstand design loads
