UN OI N <br /> COFRU�,4TING CXDAPANY <br /> Roofina <br /> Slopes of less than 3"on 12"are not recommended. For slopes of 3"on 12"or greater,end lap panels 6". Side laps should face <br /> away from the prevailing wind. Lay the frrst sheet along the eave at the down-wind side of the roof,farthest away from the <br /> direction of the prevailing winds(See Figure#4). Instalt sheets in the sequence shown in Figure#4. <br /> Figure#4 Fiaure#5-(nstallation Options <br /> Prevailin9 <br /> /Winds � tlOfl 1 <br /> � P O tion 2 O tion 3 <br /> `�\�a wa� <br /> ,,, ,sx"'�'\,,:� �2'x4'S <br /> l'���,o �„�� �1����'\` 2'Spacing <br /> ��;,,'�Y UnionfeHSynthetic Union�@HSynthetic <br /> r,'r•���r;.�' ;';:'„r�..

Use inside closure at eave to prevent water infiltra- <br /> tion,insect or bird infestation at openings.To protect against uplifting winds and to provide a finished appearance,apply rake <br /> trim or other standard gable trim. For slopes less than 3:12,apply 3/8"tape sealant as shown in Figure#6 along the top of all <br /> lap ribs. Do not block the siphon channel with the tape. For best results,apply a 7/8"lap tek screw into the crown of the rib to <br /> secure the side lap. <br /> Fiaure#6-Proper Application of Side Lap Tape <br /> 7/8'Lap Tek Screw at 24"O.C. <br /> 3/8°Butyl Tape Sealant <br /> �� <br /> Allowable Uniform Loads Per Square Foot <br /> LIVE LOAD (PSF) WIND LOAD (PSF) <br /> SPAN nrvcHES� 18" 24" 30" 36" 48" 54" 18" 24" 30" 36" 48" 54" <br /> 29 Gau e 199 112 71 49 28 22 217 118 7b 52 29 23 <br /> 26 Gauge 268 150 96 67 37 29 276 155 99 69 38 30 <br /> NOTES: <br /> 7.Theoretical allowable loads are based on section properties and allowables calculated in accordance with 2007 AISI Specifications. <br /> 2.Theoretical allowable loads are based on three or more uniform spans. <br /> 3.For roof panels,deduct self weight for actual`live load'capacity of the panel. <br /> 4.These loads are for panel strength.Frames,purlins,decks and fasteners must be designed to resist all loads imposed on the panel. <br /> 5.Check local building codes if panel testing is required. <br /> � <br />
