Notes:
1.  Allowable loads shown are based on 1980 edition of AISI
     specifications.
2.  Deflection is limited to L/240 of span.
3.  Loads are based on spans of 3 or more.
4.  FY = 50 ksi for steel panels.
5. Uplift values based on attachment to 16 ga. purlins with
     2 - #10-16 x 1" SD ST screws.

TEST REPORT SUMMARIES

AIR INFILTRATION:  had 0.01 cfm / SF leakage with 15 psf pressure differential per ASTM E 283.

WATER RESISTANCE:  No water penetration under 5 gallon per hour spray at 6.24 psf pressure differential per ASTM E 331.

UL90 UPLIFT RATING:  16" wide, 24 ga. steel panels with clips installed over 16 ga. purlins (40 ksi steel) and spaced maximum of 5'-0" O.C. with one screw per clip.  Insulation varies with Construction No.  (Construction No. 90, 176, and 180.)

UL90 UPLIFT RATING:  16" wide, 24 ga. steel panels with clips spaced a maximum of 48" O.C. over rigid insulation (min. 1" thickand 2.0 pcf) over 22 ga. steel deck (33ksi) with one #11 x 3 ¾" long self-drilling screw with Phillips drive and flat head per clip and bearing plate under each clip.  Bearing plate is 0.050" x 3" x 3.25".  (Construction No. 238.)

UL90 UPLIFT RATING:  16" wide, 24 ga. steel panels with clips spaced a maximum of 2'-0" O.C. installed over ½" plywood deck with two #12-14 x 1" pancake head screws per clip.  (Construction No. 548.)

UL90 UPLIFT RATING:  16" wide, 24 ga. steel panels with clips spaced a maximum of 5'-0" O.C. installed over 5/8" plywood deck with two #10 x 1" pancake head screws per clip.  (Construction No. 549.)  Fabral recommends a maximum clip spacing of 2'-0" O.C. for installations over plywood.
