Mold Resistance Independent tests confirm that DensGlass Sheathing,with its patented fiberglass mat design,resists the growth of mold when tested,as manufactured,per ASTM D 3273. Strength Fiberglass mats penetrate into the panel to make an integrated unit that offers superb strength;outstanding resistance to delamination, deterioration,warping and job site damage;and an excellent bonding surface for EIFS.The flexural strength of DensGlass Sheathing is approximately the same in both directions.This means DensGlass Sheathing can be installed either vertically or horizontally without sacrificing wall strength between studs.DensGlass panels also protect and help stabilize structural framing. Stability DensGlass Sheathing is extremely resistant to rippling,buckling and sagging,even under humid conditions—which makes it particularly suitable for soffits. In actual tests, DensGlass panels exceeded ASTM C 1396 and ASTM C 79 standards for humidified deflection by a factor of five times over the standard for paper-faced gypsum sheathing. Fire Resistance DensGlass Sheathing is noncombustible as described and tested in accordance with ASTM E 136.Tests of 5/8"(15.9 mm) DensGlass®Fireguard®Sheathing conducted in accordance with ASTM E 119/CAN ULC S-101 qualify the product for a variety of UL listings and other designs in the GA-600 Fire Resistance Design Manual. Superior Weather Protection DensGlass Sheathing integrates a water-resistant,treated core with a fiberglass mat face and back to provide superb protection from the elements.Panels will not delaminate or deteriorate due to normal weather conditions—even during construction delays that last as long as 12 months after installation. A water-resistive barrier is not required over DensGlass Sheathing to provide for the protection of the gypsum sheathing itself.Consult with the local building code,design professional,owner or cladding manufacturer for water-resistive barrier requirements. DensGlass Sheathing is the ideal substrate for a wide variety of air and water-resistive barriers including building wraps,liquid applied coatings and self-adhering membranes. See page 9 for details.

Avoid any condition that will create moisture in the air and condensation on the exterior walls during periods when the exterior temperature is lower than the interior.The use of forced air heaters creates volumes of water vapor which,when not properly vented,can condense on building materials.The use of these heaters and any resulting damage is not the responsibility of Georgia-Pacific Gypsum.Consult heater manufacturer for proper use and ventilation.Vapor barrier may also restrict ventilation. When DensGlass Sheathing panels are used in slanted wall applications,that portion of the wall must be temporarily protected from the elements by the use of a water-resistant barrier prior to application of the cladding. Do not allow water to pond or settle on sheathing.Also,exposed wall ends such as those that may be found in parapets must be covered to prevent water from infiltrating the cavity. Georgia-Pacific Gypsum does not warrant and is not responsible or liable for the performance of the cladding or exterior systems applied over DensGlass Sheathing.The suitability and compatibility of any system is the responsibility of the system manufacturer or design authority. Do not laminate DensGlass Sheathing to masonry surfaces; use furring strips or framing. DensGlass Sheathing is not intended for roof applications.For roof applications,consult our DensDeck®Roof Board brochure. DensGlass Sheathing is not intended for interior or exterior tile applications.For interior tile applications,consult our DensShield® Tile Backer brochure. DensGlass Sheathing should not be used in lieu of plywood where required. Do not apply DensGlass Sheathing below grade. For all installations,design details such as fasteners,sealants and control joints per system specifications must be properly installed.Openings and penetrations must be properly flashed and sealed. Failure to do so will void the warranty. Do not use DensGlass Sheathing as a base for nailing or mechanical fastening.Fasteners should be flush to the face of the board,not countersunk.
