Roof membranes are subsequently fully adhered. All General and System Limitations apply. One or more layers of any of the following insulations: Base Insulation Layer Insulation Fasteners Fastener (Table 3) Density/fe ENRGY 3 Minimum 1.5" thick N/A N/A One or more layers of any of the following insulations: Top Insulation Layer Insulation Fasteners Fastener (Table 3) Density/ft2 Georgia-Pacific High Density Roof Fiberboard Minimum I/z" thick N/A N/A Concrete deck shall be primed with ASTM.D 41 asphalt primer and allowed to dry prior to application of base insulation. All insulation shall be adhered in full mopping of approved hot asphalt or coal tar pitch within the EVT range and at a rate of 20-40 Ibs/100 fe. Please refer to Roofing Application Standard RAS 117 for insulation attachment. Insulation listed as base layer only shall be used only as base layers with a second layer of approved top layer insulation installed as the final membrane substrate. Composite insulation panels may be used as a top layer placed with the polyisocyanurate side facing down. 14* Base Sheet: Durapax Organic Base Sheet or Durapax Glass Fiber Base Sheet in a full mopping of approved asphalt applied within the EVT range and at a rate of 20-40 � lbs./sq. 8Ply Sheet: Two or more plies of Durapax Tarred Felt, Durapax TC Glass Fiber felt or Durapax TC Premium Glass Fiber Felt adhered in a full mopping of hot Durapax Coal Tar Roofing Pitch applied at not less than 20 lbs./sq.

If mechanical attachment to the structural deck through the lightweight insulating concrete is proposed, a field withdrawal resistance testing shall be performed to determine equivalent or enhanced fastener patterns and density. All testing and fastening design shall be in compliance with Testing Application Standard TAS 105 and Roofing Application Standard RAS 117, calculations shall be signed and sealed by a Florida Registered Engineer, Architect, or Registered Roof Consultant. GENERAL LIMITATIONS: 1. Fire classification is not part of this acceptance, refer to a current Approved Roofing Materials Directory 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 layers shall be adhered in a full mopping of approved asphalt applied within the EVT range and at a rate of 20-40 lbs./sq., or mechanically attached using 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' maximum. 4. An overlay and/or recovery board insulation panel is required on all applications over closed cell foam insulations when the base sheet is fully mopped. If no recovery board is used the base sheet shall be applied using spot mopping with approved asphalt, 12" diameter circles, 24" o.c.; or strip mopped 8" ribbons in three rows, one at each sidelap and one down the center of the sheet allowing a continuous area of ventilation. Encircling of the strips is not acceptable. A 6" break shall be placed every 12' in each ribbon to allow cross ventilation. Asphalt application of either system shall be at a minimum rate of 121bs./sq. Note: Spot attached systems shall be limited to a maximum design pressure of 45 psf. 5. Fastener spacing for insulation attachment is based on a Minimum Characteristic Force (F) value of 275 lbf., as tested in compliance with Testing Application Standard TAS 105. If the fastener value, as field-tested, are below 275 lbf. insulation attachment shall not be acceptable. 6. Fastener spacing for mechanical attachment of anchor/base sheet or membrane attachment is based on a minimum fastener resistance value in conjunction with the maximum design value listed within a specific system. Should the fastener resistance be less than that required, as determined by the Building Official, a revised fastener spacing, prepared, signed and sealed by a Florida registered Professional Engineer, Registered Architect, or Registered Roof Consultant may be submitted. Said revised fastener spacing shall utilize the withdrawal resistance value taken from Testing Application Standards TAS 105 and calculations in compliance with Roofing Application Standard RAS 117. 7. Perimeter and comer areas shall comply with the enhanced uplift pressure requirements of these areas. Fastener densities shall be increased for both insulation and base sheet as calculated in compliance with Roofing Application Standard RAS 117. Calculations prepared, signed and sealed by a Florida registered Professional Engineer, Registered Architect, or Registered Roof Consultant (When this limitation is specifically referred within this NOA, General Limitation #9 will not be applicable.) 8. All attachment and sizing of perimeter nailers, metal profile, and/or flashing termination designs shall conform with Roofing Application Standard RAS 1 I 1 and applicable wind load requirements. 9. The maximum designed pressure limitation listed shall be applicable to all roof pressure zones (i.e. field, perimeters, and comers). Neither rational analysis, nor extrapolation shall be permitted for enhanced fastening at enhanced pressure zones (i.e. perimeters, extended comers and comers). (When this limitation is specifically referred within this NOA, General Limitation #7 will not be applicable.) 10. All products listed herein shall have a quality assurance audit in accordance with t 111a ldi e Rule 9N-3 of the Florida Administrative Code.
