Georgia-Pacific Gypsum is not responsible for product damage or defects resulting from incorrect application, storage, handling or abuse. Gypsum Board Edge Details Tapered The tapered edge was originally called the “recessed edge.” This taper allows space for tape and joint treatment to be applied, so the completed job will be flat, smooth and monolithic. Width of taper is about 2” (51 mm). TE Square Square edge was the original wallboard edge. Initially designed to be a base with a final covering such as wallpaper, paneling or tile. Now manufactured primarily as sheathing and backer board. S Tapered with Round Edge Round edge is designed to reduce beading and ridging problems commonly associated with standard gypsum board. RE Double Beveled Shaftliner panels are produced with double beveled edges to allow a quick, easy fit into the metal framing of shaftwall, stairwell and area separation walls.

Product Selection Guide For latest information and updates: Technical Service Hotline 1.800.225.6119 or www.gpgypsum.com CAUTION: For important fi re, safety and use information, go to page 7.7 Important Safety and Use Information The following contains important safety and use information concerning Georgia-Pacific Gypsum products, including information regarding fire, sound, moisture and mold resistance. However, please note the information contained in this directory may change without notice. For current product fire, safety and use information, go to www.buildgp.com/safetyinfo or call 1-800-225-6119. Fire and Sound Resistance Information presented in this directory concerning fire resistance ratings (such as 1-hour or 2-hour ratings) is presented for illustration purposes only and reflects the results of tests conducted on systems composed of specific materials assembled in a specific manner or independent approvals based on further evaluations or inferences from such tests. The use of other materials or construction methods may adversely affect performance. In addition, independent organizations such as UL may authorize specific products to be labeled as acceptable for use in certain fire-rated systems, based on criteria deemed appropriate by such organizations, without requiring a full-scale fire test of the systems including that product. Please consult the appropriate fire resistance directory, such as UL’s Fire Resistance Directory, for information concerning each fire resistance rating and assembly. Passing a fire test in a controlled laboratory setting and/or certifying or labeling a product as having a one-hour, two-hour, or any other fire resistance or protection rating and, therefore, acceptable for use in certain fire-rated assemblies/systems, does not mean that either a particular assembly/system incorporating the product, or any given piece of the product itself, will necessarily provide one-hour fire resistance, two-hour fire resistance, or any other specified fire resistance or protection in an actual fire. In the event of an actual fire, you should immediately take any and all actions necessary for your safety and the safety of others without regard for any fire rating of any product or assembly/system. “Type X” as used in this directory designates gypsum board manufactured and tested in accordance with specific ASTM standards for increased fire resistance beyond regular gypsum board. Please consult the ASTM standard for the specific product (for example, ASTM C1396 for standard gypsum board and ASTM C1658 for glass mat gypsum panel products) for further information and significance of use. Generic systems in the GA-600 Fire Resistance Design Manual are applicable to the products of any manufacturer, including Georgia-Pacific Gypsum, provided they meet certain standards set forth in such manual, such as Type X gypsum board per applicable ASTM standard with specified thickness and size described in the design. “Noncombustible” as used in this directory is based on testing of identified products, as manufactured, in accordance with ASTM E136. This ASTM standard is used to measure the response of products to heat and flame under controlled laboratory conditions but does not purport to address all of the fire safety concerns, if any, associated with the product. Please consult ASTM E136 for further information and significance of use. Information in this directory relating to sound resistance is based on the characteristics, properties and performance of materials and systems obtained under controlled test conditions as set forth in applicable ASTM standards, such as ASTM E90. Conditions caused by design, installation or other factors may adversely impact sound resistance in any structure, and therefore the sound resistance of any building product when used in actual job site conditions may not produce the same results achieved in the controlled, laboratory setting. For latest information and updates: Technical Service Hotline 1.800.225.6119 or www.gpgypsum.com CAUTION: For important fi re, safety and use information, go to page 7.8 Product Selection Guide Moisture and Mold Resistance Moisture resistance and mold resistance, as used in this directory, are determined on the basis of applicable ASTM standards. For example, moisture resistance of gypsum panels is generally determined in accordance with Section 20 of ASTM C473. While some products are subject to limited warranties for normal weather exposure, other products are not intended for immersion in water and should be handled and stored in accordance with Georgia-Pacific Gypsum guidelines and good industry practice. Unless specifically indicated, mold resistance is based on testing of products, as manufactured, in accordance with ASTM D3273. A score of 10, the highest level of performance for mold resistance under the ASTM D3273 test method, indicates no mold growth in a 4-week controlled laboratory test. The mold resistance of any building product when used in actual job site conditions may not produce the same results as were achieved in the controlled laboratory setting. No material can be considered mold proof, as mold can grow on virtually any surface when exposed to the right elements. When properly used with good design, handling and construction practices, Georgia-Pacific Gypsum’s Dens® Brand gypsum products and ToughRock® Mold-Guard™ gypsum products provide increased moisture and mold resistance compared to standard paper-faced wallboard. Delivery, Handling and Storage All materials shall be delivered in original bundles bearing the brand name, if any; applicable product standard designation; and name of the manufacturer or supplier for whom the product is manufactured. The plastic packaging used to wrap gypsum panel products for rail and/or truck shipment is intended to provide temporary protection from moisture exposure during transit only and is not intended to provide protection during storage after delivery. Such plastic packaging shall be removed immediately upon receipt of the shipment. WARNING: Failure to remove protective plastic shipping covers can result in condensation which can lead to damage, including mold. All materials should be kept dry. Gypsum panel products shall be neatly stacked flat with care taken to prevent sagging or damage to edges, ends and surfaces. Gypsum panel products and accessories shall be properly supported on risers on a level platform, and fully protected from weather, direct sunlight and condensation. Gypsum panel products shall be stacked flat rather than on edge or end. WARNING: Gypsum panel products stacked on edge or end can be unstable and present a serious hazard in the workplace should they accidentally topple. Refer to Handling Gypsum Panel Products, GA-801, for proper storage and handling requirements. Reference: Application and Finishing of Gypsum Panel Products, GA-216, Gypsum Association. Gypsum Boards and Panels CAUTION: Some of these products contain fiberglass and/or fiberglass facings which may cause skin irritation. Dust and fibers produced during the handling and installation of the product may cause skin, eye and respiratory tract irritation. Avoid breathing dust and minimize contact with skin and eyes. Wear long sleeve shirts, long pants and eye protection. Always maintain adequate ventilation. Use a dust mask or NIOSH/MSHA approved respirator as appropriate in dusty or poorly ventilated areas.
