R = Total thermal resistance of the assembly without roofing. 2. Assumes thermal conductivity (k) of 0.15. Some insulations have superior values. Check with manufacturer. 3. Some codes allow up to 20% increase in R values of insulation which is continuous. Check local codes for adjustment factors. Footnotes for Span Tables: 1. Values followed by (f) are governed by stress. Allowable loads for floors when governed, by deflection are half of those listed in the 1 /180 column. 2. Bending stress relates to 2-month duration. It is not exceeded when the listed loads are applied based on recognized decking formulas. 3.

Application of 5230 Adhesive is a simple and effective way to use Lock -Deck laminated decking to its fullest structural potential. FINISHES DIAPHRAGM CONSTRUCTION. Used in combination with 3M's 5230 elastomeric adhesive, LOCK -DECK can be engineered to carry diaphragm shear. This system com- bines the proven structural strength of LOCK -DECK deck- ing with the strong durable characteristics of this adhesive. Results in a strong, adequately rigid, yet flexible, glue joint which absorbs much of the shock wave energy from dynamic loads such as wind, earthquake and other severe stresses.

Lock -Deck laminated decking can be easily handled and installed on most construction projects. >< '""`*' RANDOM LENGTH CONTINUOUS: Random Length Continuous, or RLC, is the most common method of apply- ing LOCK -DECK decking. It allows the use of mixed lengths of material on a variety of span conditions, providing high structural efficiency and attractive appearance. The allowable RLC roof loads recommended in the span table are based on actual full-scale tests, where the decking was laid in conformance with certain rules. Equivalent performance will be obtained by following these rules: 1. The deck must be continuous over three or more spans of approximately equal length, with each piece of deck over at least one support. Other situations require special design. 2. Decking shall be laid to disperse end -joints as randomly as possible, so that: a) The distance between end -joints in adjacent rows of decking is at least two feet. b) The distance between end -joints in rows of decking separated by only one row is at least one foot. 3. End spans shall be carefully planned and laid. To ensure that end spans perform as indicated by the span tables, follow one of these practices: a) Eliminate end -joints in one-third of the courses of decking, or b) Provide a cantilevered overhang, free of end -joints, equal to 20% of the end span, or c) Shorten the end span by 10%. Where one of these practices cannot be applied, end span deflection may exceed the values shown. Construction practice has accepted this in many instances. 4. Decking should be end -matched and toenailed within one foot of all ends (see Attachment Procedures, this page). BuyLine 5112 ATTACHMENT PROCEDURES.
