Description

LightRoc® gypsum wallboard is lighter in weight than traditional 1/2” drywall and is designed for use in wall and ceiling applications spaced no more than 24”o/c. LightRoc® is 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 LightRoc Lightweight Gypsum Wallboard panels have 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 formaldehyde.
