The panels have a nominal thickness of 3, 4 or 6 inches (76, 102 and 152 mm), are nominally 48 inches (1219 mm) wide and are available in various lengths. The wall panels are limited to the maximum 3-inch (76 mm) thick panels. As an option, the roof panels may include an internal aluminum beam channel factory-installed parallel to the length of the panel and centered on the panel width. The attributes of the sandwich panels have been verified as conforming to the provisions of (i) 2016 and 2013 CALGreen Sections A for premanufactured building systems; (ii) ICC and ICC Section and for prefabricated components; and (iii) ICC Section for prefabricated components. Note that decisions on compliance for those areas rest with the user of this report. The user is advised of the project-specific provisions that may be contingent upon meeting specific conditions, and the verification of those conditions is outside the scope of this report. These codes or standards often provide supplemental information as guidance. 3.2 Materials: Panel Core: The foam plastic core material is either a 1.0 pcf nominal density, Type I or a 2.0 pcf nominal density, Type IX, expanded polystyrene (EPS) foam plastic board complying with ASTM C578, specified in the approved United Duralume Products quality control manual. The foam plastic has a flame-spread index of 25 or less and a maximum smoke-developed index of 450 when tested in accordance with ASTM E Panel Facings: The aluminum facing material on both faces of the panels is 3105-H24 or 3105-H25 aluminum having a base-metal thickness of inch (0.61 mm). The minimum tensile ultimate and yield strengths of the 3105-H24 panel facings are 22 ksi (152 MPa) and 18 ksi (124 MPa). The minimum tensile ultimate and yield strengths of the 3105-H25 panel facings are 23 ksi (159 MPa) and 19 ksi (131 MPa), respectively Panel Laminating Adhesive: The facings are factory-laminated to the panel core and aluminum fan beam, as applicable, with an adhesive, described in the approved United Duralume Products quality control manual, that is a Type II, Class 2, adhesive complying with the ICC-ES Acceptance Criteria for Sandwich Panel Adhesives (AC05) Aluminum Fan Beam: The aluminum fan beam is a rectangular extruded aluminum tube. The aluminum has alloy and temper of 6063-T5.

The fan beam is inserted in the foam core at the bottom center of the roof panel and runs the entire length of the panel Gypsum Wallboard Attachment Adhesive: Liquid Nails Heavy Duty Construction (Model LN 901 or LNP 901) Adhesive is jobsite-applied and is used to bond the gypsum wallboard to the interior face of the wall panels. The adhesive is a solvent adhesive manufactured by PPG Industries. The weight of the adhesive is 9.4 lbs per gallon (1.13 kg/l). Shelf life is one year. 4.0 DESIGN AND INSTALLATION 4.1 Design: Allowable transverse loads for roof and wall panels are noted in Table 1. The roof panels must be selected based on a minimum allowable transverse live load of 10 psf (478.8 Pa) as permitted for patio covers under Appendix H of the IRC, or the actual snow load, whichever is greater. The wall and roof panels must be selected based on the design transverse wind load determined in accordance with ASCE 7. Calculations demonstrating adequacy of the roof and wall panel supports and connections for the imposed loads must be furnished to the code official for approval. Use of roof and wall panels as bracing against lateral wind or earthquake forces is outside the scope of this evaluation report. 4.2 Installation: Installation must be in accordance with United Duralume s installation instructions and this report. This report and United Duralume s installation instructions must be available at the jobsite at all times during construction. The minimum bearing width of supports at each end of the roof and wall panels subjected to transverse loads is 1-inch (25.4 mm). As an alternative, to restrain the panels subjected to wind uplift or negative loads, the panels must be attached to the supports with the use of corrosionresistant fasteners installed with 1-inch-outside-diameter (25.4 mm) corrosion-resistant steel plate washers with neoprene inserts. The fastener spacing is limited to a maximum distance of 12 inches and must be determined by a registered design professional as indicated in Table 1. At least two fasteners per panel are required at each end support. The panels must be installed continuous without transverse joints. The roof panels must be installed with a roof slope equal to, or greater than, the slope indicated in Table 1 for the most severe applicable loading condition. Roof panels with a fan beam insert must be installed with the fan beam on the bottom of the roof panel. The design of the supporting structure and connection of the panels to the supporting structure must be substantiated to the satisfaction of the code official. The wall and roof panels must be interlocked. Openings in wall panels are outside the scope of this report. 4.3 Thermal Barrier: A thermal barrier consisting of ½-inch-thick (12.7 mm) gypsum wallboard complying with ASTM C36 or ASTM C1396 must be attached to the interior face of the wall panels using ¼-inch-wide (6 mm) bead of the Liquid Nails adhesive, applied to the metal facer of the sandwich panel in a zigzag pattern in rows 24 inches (610 mm) on center and 2 inches (51 mm) from edges. A thermal barrier, as required by the applicable code, is not required on the interior side of the roof panels. The distance from the panel seam of the roof panel to the interior face of the wall parallel to the seam must be a minimum of 43 inches (1093 mm). 5.0 CONDITIONS OF USE The Duracool Composite Structural Insulated Panels described in this report comply with, or are a suitable alternative to what is specified in, those codes listed in Section 1.0 of this report, subject to the following conditions: 5.1 Panel fabrication, identification and installation must comply with this report and the manufacturer s approved quality control manual and published installation instructions.

Consideration shall be given to non-uniform loads such as those associated with snow buildup and areas of discontinuity for wind loads. 3 Unless otherwise noted, the maximum eave projection of the roof system is 24 inches. 4 Tabulated spans are based on wall and roof panels supported at the panel ends with 1-inch bearing width. As an alternate when resisting wind uplift or negative loads, the wall or roof panels must be restrained at the panel ends from wind uplift with the following provisions: Fasteners must be corrosionresistant No. 14 sheet metal screws with 1.0-inch-outside-diameter corrosion-resistant steel plate washers and neoprene inserts. Length of fastener shall be at least 1-inch longer than the roof panel thickness. Based on testing and a safety factor of 3.0, the allowable pull-through capacity of the fastener/panel connection is 88 lbs per fastener and washer combination. Maximum spacing of the fasteners is limited to 12 inches on center. Fastener spacing and capacity to the supporting structure when resisting wind uplift loading must be determined by a registered design professional for the specific field condition. 5 Minimum panel slopes are based on panel deflection only. Increased slopes will be required where panel accessories, such as mullions or flashing, can increase ponding caused by irregularities in the water flow path. 6 The tabulated panel spans are based on the lesser of strength limits and deflection limits. The deflection limit is 1 / 120 of the span ( L / 120 ) for both gravity and wind loads. 7 The tabulated panel spans are based on a maximum temperature differential between the two panel skins of 10 F. 8 Consideration has been given to the addition of one (1) ceiling fan per 4' wide panel with a maximum fan weight of 50 pounds. Therefore, the allowable loads provided above are in addition to the weight of the ceiling fan.
