Sag Resistant

The board contains a special dense, noncombustible gypsum core enhanced with glass fibers. It is covered with paper facings on the front (ivory), back, and long edges. The heavier-weight ivory surface will accommodate a variety of paints and textures after proper surface preparation, which includes sealing with a high-quality latex primer or sealer.

Sagcheck can be used in building applications that require direct mechanical attachment to wood or metal wall and ceiling frames, or attachment to existing surfaces using fasteners or adhesives. If using the product for renovation work, the installer should be certain to penetrate old wall or ceiling coverings to prevent the development of a vapor barrier. Likewise, a vapor barrier should not be applied behind Sagcheck.

Per ASTM C 840 and building codes, 1/2-inch Sagcheck (ceiling board meeting ASTM C 1396) is permitted to be installed with supports up to 24 inches o.c. and the board perpendicular to the framing on ceilings to receive a water-based texture.

Sagcheck is designed to provide resistance against sagging ceilings in both residential and commercial construction applications, including:

Ceilings spanning 18- to 24-inch o.c. supports;
High-humidity conditions; and
Ceilings to receive wet application texturing.
