Interior Ceiling Gypsum Board by American Gypsum

1/2” Interior Ceiling Board is specifically formulated to meet the need for a lower weight ceiling panel with increased integrity in its gypsum core, making its sag resistance equivalent to 5/8” Type X wallboard. American Gypsum’s 1/2’’ Interior Ceiling Board is designed for use in wall and ceiling applications spaced no more than 24’’ o/c, and approved to be applied parallel or perpendicular to ceiling framing spaced up to 24’’ o/c, even when a hand applied or water-based texture is used for decoration.

The exceptional sag resistance of American Gypsum’s Interior Ceiling Board has been independently verified by Progressive Engineering, Inc. when tested in accordance with ICC-ES AC417 (Acceptance Criteria for 1/2 Inch Sag-Resistant Gypsum Ceiling Board), and PEI Standard No. 94-9 – Large Scale Ceiling Board Load Test Procedure.

American Gypsum products contain no asbestos and no detectable levels of formaldahyde.

Basic Uses
5/8″ wallboard panels were once considered the best product for ceiling applications where the framing is spaced up to 24″ o/c. However, product weight has always been a hindrance to proficient construction. The lighter weight 1/2″ Interior Ceiling Board is specifically designed for interior ceilings in standard residential and commercial applications where framing members are spaced up to 24″ o/c and a water-based texture will be used.

Interior ceiling gypsum wallboard has achieved UL Environment’s GREENGUARD GOLD Certification. GREENGUARD Certified products are scientifically proven to meet some of the world’s most rigorous, third-party chemical emissions standards, helping reduce indoor air pollution and the risk of chemical exposure while avoiding in the creation of healthier indoor environments.
