Page 11 of 14 National Evaluation Report No. NER-520 Footnates for Racking Load Table Panels are made of two equal layers of APA or TECO rated OSB sheathing. The core shall be nominal 1.0 pcf density(min. 0.9 pcfl EPS (expanded polystyrene)foam adhered to the sheathing with glue and set under pressure. 1. Allowable load of 208 plf is based on using surface splines consisting of minimum 3 inch wide, 5/8 inch thick AD plywood at all panel edges, both sides. Panel skins shall be stapled to the splines using minimum 16 ga., 7/16 inch crown by 1-3/4 inch long staples along all panel edges at 6 inches on center, both sides. 2. Allowable load of 385 plf is based on using minimum 2x SPF solid sawn lumber splines at all panel edges. Panel skins shall be nailed to the splines using minimum 8d common nails along all panel edges at 6 inches on center, both sides. Footnotes for Transverse Loads Tables Panels shall be made of two equal layers of APA or TECO rated OSB sheathing.The core shall be nominal 1.0 pcf density (min. 0.9 pcfl EPS(expanded polystyrene)foam adhered to the sheathing with glue and set under pressure. In panels with spline studs,the skins shall be nailed to the spline studs with 6d nails @ 6 inches o.c.When the tables indicate that no spline studs are required for structural capacity, it is permitted to join adjacent panels using 3 inch (76.2 mm)wide, 5/8 inch (15.9 mm)thick plywood or OSB surface splines under the skins of each face instead of spline studs. The surface splines shall be installed using a gap filling expanding foam sealant and 1-1/4 inch (25.4 mm) long, No. 6 screws at 6 inches(152 mm) on center on each side of the joint. 1. Values shown are allowable spans due to dead load plus live load. 2. The tables reflect two deflection criteria. For all panels the deflection criteria of L/360 shall be used for floor loads. For roof panels with slopes less than 3 in 12 pitch,the L/360 deflection criterion shall be used. For roof panels with slopes of 3 in 12 or greater, the deflection criterion of L/240 shall be acceptable. 3. To minimize deflection creep on panels without splines loaded with permanent or long-duration loads (> 6 mo.), find the allowable span on the table for twice the actual load (i.e. use 40 psf for actual load of 20 psf.) 4. Some allowable spans are not based on deflections, therefore, no multipliers for other deflection criteria shall be allowed. 5. All values are for normal duration loads. No increases for other durations are allowed. 6. Maximum spans are limited to the maximum panel size, 28 feet. 7. All values listed are for single-span panels with supports at each end. 8. For eight foot wide panels with splines at 8'-0" o.c., use table values for sandwich panels without splines; for panels with splines at 4'-0"o.c., use tables for single splines. 9. All values are based on INSULSPAN -Transverse Load Tables (T.1 -T.38), "OINSULSPAN 1999", dated September 9, 1999. Footnotes for Axial Load Tables Panels shall be made of two equal layers of APA or TECO rated OSB sheathing.The core shall be nominal 1.0 pcf density (min. 0.9 pc� EPS(expanded polystyrene)foam adhered to the sheathing with glue and set under pressure. In panels with spline studs,the skins shall be nailed to the spline studs with 6d nails @ 6 inches o.c.When the tables indicate that no spline studs are required for structural capacity, it is permitted to join adjacent panels using 3 inch (76.2 mm)wide, 5/8 inch(15.9 mm)thick plywood or OSB surface splines under both exterior and interior skins instead of spline studs.The surface splines shall be installed using a gap filling expanding foam sealant and 1-1/4 inch (25.4 mm) long, No. 6 screws at 6 inches(152 mm)on center on each side of the joint 1. Values shown are allowable heights due to dead load plus live load. 2. Allowable loads are based on axial loads being applied over the entire panel width. 3. A deflection criterion of H/240 is used. 4. Some allowable spans are not based on deflections, therefore, no multipliers for other deflection criteria shall be allowed. 5. All values are for normal duration loads. No increases for other durations are allowed. 6. Maximum spans are limited to the maximum panel size, 28 feet 7. All values listed are for single-span panels with supports at the top and bottom. 8. Where no allowable height is shown, panel does not meet criteria to carry applied axial load. 9. For panels with splines at 24"o.c. use the allowable heights of panels with double splines. 10. For eight foot wide panels with splines at 8'-0"o.c., use table values for sandwich panels without splines; for panels with splines 4'-0"o.c., use tables for single splines. 11. All values are based on INSULSPAN -Axial Load Tables(A.1 -A.200), "OINSULSPAN 1999", dated September 9, 1999. 1_0 SUBJECT 3.0 DESCRIPTION 6_0 EVIDENCE SUBMITTED 2_0 PROPERTY FOR WHICH 4_0 INSTALLATION 7_0 CONDITIONS OF USE EVALUATION IS SOUGHT 5_0 IDENTIFICATION Re-Issued November 1, 2002 NES back to the NES home paqe National Evaluation Service, Inc.
