STEEL DECK SYSTEM LIMITAT10N5: <br /> i. If inechanical attachment to the structural deck through the lightweight insulating concrete is proposed, A field <br /> tivithdrawal resistance testing shall be performed to determine fastener patterns and density. All testing and fastening <br /> design shall be in compliance with Testing Application Stmndard TAS 105 and Roafing Application StandArd RAS <br /> 117 andlor RAS 137, calculations shall be signed and sealed by a Florida registered Professionul Engineer, <br /> Registered Architect,or Regisiered Roof Consultant. <br /> 2. For steel deck application where specific deck consuuction is not referenced: The deck shall be a minimum 22 gage <br /> att�ched with 5/R"puddle�velds with weld���ashers at every ffute with maximum deck spans of 5 ft.o.c. <br /> GENERAL LIMITATIONS: <br /> 1. Fire classification is not part af this acceptance, refer to a current Approved Roo�ng Mtaterials Directorv for fire <br /> r�tings�f diis producl. ' <br /> 2. Insulution may be installed in multiple layers. Tile�rst layer shall be attached in compliance with Product Control <br /> rlpproval guidelines. All other layers shall be udhered in a fiill mopping of approved asphalt applied�virthin the <br /> EVT range and at a rate of 20-40 Ibs./sy.,or mechanically attached using the fastening p�ttern of the top layer <br /> 3. Alt standArd panel sizes are �cceptable For mechanical attAchment. When Applied in approved asphult, panel size <br /> shatl be 4'x�'maximum. <br /> 4. An averlay and/or recovery board insulation panel is required on all applicutions over closed cell faam insulations <br /> �vhen the base sheet is fully mopped. If no recovery board is used the base sheet shall be applied using spot rnopping <br /> �vith approved asphait, 12" diameter circles. 24" o.c.; or strip mopped �" ribbons in three rows, one at each sidelap <br /> nnd one down the center of the sheet allowing a contimious areu of ventilation. EncircGng of the svips is not <br /> �ccept�ble. A G" breuk shall be placed every 12' in each ribbon to allow cross ventilation. Asphalt application af <br /> either system shall be at a minirnum rate of 12 Ibs.!sq. Nate: Spot attache�l systems shall he limited to � <br /> m�simum desi�n pressure af-4S psf. <br /> �. Fastener spacing for insulation attachinent is based on a Minimum Gharacteristic Force(F')�alue of 275 Ibf.,as <br /> tested in compliance with Testing Application Stundard TAS 105. If the fastener��alue,as�eld-tested,are belo�v <br /> 275 lbf. insul�tion atiachment shall not be acceptable. <br /> 6. Fastener spacing for mechanical attachment of anchor/base sheet or membrane attachment is based on a minimum <br /> fastener resistance value in conjunction w•ith tl�e maximum design value listed within A specific system. Should the <br /> fastener resistance be less than that required,as determined by the Building Q�cial,a revised fastener spacin�, <br /> prepared,signed and sealed by a Florida Registered Engineer.Architect, or Registered Roof Consuhant may be <br /> submitted. Said revised fastener spacing shall utilize the withdrawal resistance value taken From Testing <br /> Application Standards TAS 1Q5 and calculations in compliance with Roo�ng Application Standurd RAS I 17. <br /> 7. Perimeter And corner arels shall comply «rith the enhanced uplift pressure requirements of thcse areas. FAstener <br /> densities shall be increased for both insulatian and base sheet as calculated in compliance with Roofing Application <br /> Sttrndard RAS 117 and/or RAS 131. (When this limitation is specificall,y referred within this NQA, General <br /> Limitation#9 will not be applicable.) <br /> x, All t►ttachment and sizing of perimeter nailers,metal pro6le,and/or flashing termination designs shall confann with <br /> Roofin�;Application Standard RAS I 1 1 and applicuble wind load requirements. <br /> 9. The maxirnum designed pressure limitation listed shall be applicable to All roof pressure zones(i.e. field,perimeters, <br /> �nd corners).Neither rational analysis,nor extrupolation shall be permitted for enhanced fastening at enhanced <br /> pressure zones(i.e.perimeters,exkended corners and corners). (�Vhen this limitation is specifieallv referred <br /> within this NOA,General Limitatiun#7��•ill not be applicable.) <br /> I(�. All products listed herein shall ha��e a quAlity assurance audit in accordance with the FloridA Building Codc and <br /> Rule 9N-3 of the Florida Adminis[rative Code. <br /> END OF THIS ACCEPTANCE <br /> MIAMFDiADECOUN7Y NOA No,: 13-0411.04 <br /> �����������'"'' '�� Expiration Date: q8/31l14 <br /> aPr�•�val Date: 08/29J13 <br /> PaQe 28 af!8 <br />
