WOUD DECK SYSTEM LIMITATIONS: 1 A slip sheet is required with Ply 4 and Ply 6 when used as a mechanically fastened base or anchor sheet. GENERAL LIMITATIONS: 1 Fire classification is not part of this acceptance, refer to a current Approved Roofing Matenals Director�% for fire ratings of this product. 2 Insulation may be installed in multiple layers. The first layer shall be attached in compliance with Product Control Approval guidelines. All other lay�ers shall be adhered m a full mopping of approved asphalt applied within the EVT range and at a rate of 20-401bs./sq.,or mechanically attached usmg the fastening pattern of the top layer 3 All standard panel sizes are acceptable for mechanical attachment. When applied in approved asphalt, panel size shall be 4'x 4'm�imum. 4 An overlay andlor recovery board msulation panel is requu-ed on all applications over closed cell foam msulations when the base sheet is fully mopped. If no recovery boazd is used the base sheet shall be apphed usmg spot mopping with approved asphalt, 12" diameter circles,24" o.c.,or stnp mopped 8"ribbons m three rows,one at each sidelap and one down the center of the sheet allowing a continuous area of ventilation. Encucling of the stnps is not acceptable. A 6" break shall be placed every 12' in each ribbon to allow cross venUlat�on. Asphalt application of erther system shall be at a mimmum rate of 12 lbs./sq. Note: Spot attached systems shall be limited to a mazimum design pressure of-45 psf. 5 Fastener spacing for insularion attachment is based on a Minimum Characteristic Force(F')value of 27� lbf.,as tested in compliance with Teshng Applicat�on Standard TAS 105 If the fastener value,as field-tested, are below 2751b£ msulation attachment shall not be acceptable. 6 Fastener spacing for mechamcal attachment of anchor/base sheet or membrane attachment is based on a minimum fastener resistance value in conjunction with the ma�cimum design value hsted within a specific system. Should the fastener resistance be less than that required,as determined by the Building Official,a revised fastener spacmg, prepared,signed and sealed by a Florida Registered Engineer,Architect,or Registered Roof Consultant ma��be submitted. Said revised fastener spacmg shall utilize the withdrawal resistance value talcen from Test�ng Application Standards TAS 105 and calculations in comphance with Roofing Application Standard RAS 117 7 Peruneter and corner areas shall comply with the enhanced uplift pressure requirements of these areas. Fastener densrties shall be increased for both insulation and base sheet as calculated in compliance with Roofing Applicataon Standard RAS 117 and/or RAS 137 Calculations prepared, signed and sealed by a Flonda registered Professional Engineer, Registered Arctutect, or Registered Roof Consultant (When this limitation is specitically referred within this NOA,General Limitation#9 will not be applicable.) 8 All attachment and sizing of perimeter nailers,metal profile,and/or flashmg ternunation designs shall conform with Roofing Application Standard RAS ll 1 and applicable wind load requirements. 9 The maximum designed pressure hrmtation listed shall be applicable to all roof pressure zones(i.e. field,penmeters, and corners).Neither rational analysis,nor e�ctrapolation shall be permitted for enhanced fastemng at enhanced pressure zones(i.e.perimeters,etrtended corners and corners). (When this limitation is specifically referred within this NUA,(�eneral Limitation#7 witl not be applicable.) 1 o All membranes or packagmg shall bear the imprint or identifiable marking of the manufacturer's name or logo and the following statement: "Miami-Dade County Product Control Approved"or the Miami-Dade Counry Product Control Seal as shown below.
