STEEL DECK SYSTEM LIMITATIONS: <br /> l. If inechanical attachment to the structural deck through the lightweighi insulating concrete is proposed, a field <br /> withdrawal resistance testing sha.11 be performed to determine equiva]ent or enhanced fastener patterns and density. <br /> A1( testing and fastening design sha31 be in corr�pliance with Testing Application Standard TAS l05 and Roafing <br /> Application Standard RAS ]17 and/or RAS 137; calculations shall be signed and sealed by a FIorida Registered <br /> Engineer,Architect,or Registered Roof Consultant. <br /> 2. For steel deck application where specific deck construction is not referenced: The deck shall be a minimum 22 <br /> gage attached with S/g"puddle weids with weld washers at every flute with maximum deck spans of 5 $.o.c. <br /> GENERAL LIlVIITATIONS: <br /> 3. Fire classification is not part of this accepta,nce; refer to a current Approved Roofing Materiels Directory for f re <br /> ratings of this product. <br /> 2. Insralation may be installed in multiple layers. 'The first layer shall be attached in compliance with product <br /> Control Approval guidelines. All other layers shall be adhered in a fu1J mopping of approved asphalt applied <br /> within the EVT range and at a rate af 20-40 lbs./sq.,or mechanically attached using the fastening pattem of the <br /> top layer <br /> 3. All standard panel sizes are acceptable for mechanical attachment. When applied in approved asphalt, paneI size <br /> sha11 be 4'x 4'ma�cimum. <br /> 4. An overlay and/or recovery boazd insulation panel is required on all applicatians over closed cell foam <br /> insu3ations when the base sheet is fully mopped. If no recovery board is used the base sheet shall be applied <br /> using spat rnopping with approved asphait, 12" diameter circles, 24" o.c.; or strip mopped 8" ribbons in three <br /> rows, one at each side lap and one down the center of the sheet allowing a continuovs erea of ventilation. <br /> Encircling of the strips is not acceptable. A 6" break shall be placed every 12' in each ribbon to allow cross <br /> ventilation. Asphalt appiication of either system sha11 be at a minimum rate of 12 ibs./sq. Note: Spot attached <br /> syatems shaII be limited to a mazimum design pressure of-45 pef. <br /> 5. Fastener spacing for insulation attachment is based on a Minimum Characteristic Force(F')value of 275 lbf.,as <br /> testec3 in compliance with Testing Application Standard TAS 105. lf the fastener value,as field-tested,are <br /> below 275 lbf.InsuIation attachment shall not be acceptable. <br /> 6. Fastener spacing for mechanical aitachment of anchor/base sheet or membrane attachment is based on a <br /> minimum fastener resistance vaIue in conjunction with the maximum design value listed within a specific <br /> system. Should the fastener resistance be less than that required,as detetmined by the Building Official,a <br /> revised fastenar spacing,prepared, signed and sealed by a Florida registered Professional Engineer,Registered <br /> Architect,or Registered Roof Consultant may be submitted. Said revised fastener spacing shall utilizc the <br /> withdrawaI resistance value taken from Testing Application Standards TAS 105 and calculations in compliance <br /> with Roofing Application Star�dard RAS 117. <br /> 7. Perimeter and corner aress shall comply with the enhanced uplift pressure requirements of these areas. Fastener <br /> densities shall be increased for both insulation and base sheet as calculated in comptiance with Roofng <br /> Application Standard RAS l I 7 and/or RAS 137. Calculations prepared,signed and sealed by a Florida registered <br /> Professional Engineer, Registered Architect, or Registered Roof Consultant (When this limitation is <br /> speciSeally referred within this NOA,General Limitation#9 will nat be applicable.) <br /> 8. All attachment and sizing of perimeter nailers,metal prof le,and/or flashing termination designs shall conform <br /> to Roofing Application Standard RAS 111 and applicable wind load requirements. <br /> 9. The maximum designed pressure limitation listed shall be applicable to all roof pressure zones(i.e. field, <br /> perimeters, and corners).Neither rational anaiysis,nor extrapolation shall be permitted for enhanced fastening at <br /> enhanced pressure zones(i.e.perimeters,extended corners and corners).(When this limitation ia specifically <br /> referred withia this NOA,General Limitation#7 will not be applicable.) <br /> 10. All products�isted herein shall have a quality assurance audit in accordance with#he Florida Building Code and <br /> Rule 9B-72 of the Florida Administrative Code. <br /> END OF THIS ACCEPTANCE <br /> NOA No.: 11-0113.02 <br /> Ezpiration Dnte: 04/28/16 <br /> ` �� Approv$1 Date: 04l2I/l I <br /> Page 8 af 8 <br />
