Description Sh e e t r o c k
®
brand gypsum panels are factory-fabricated, composed of a fire-resistant gypsum core encased
in heavy natural-finish face paper and strong liner paper on the back side. The face paper is folded around the
long edges to reinforce and protect the core, and the ends are square-cut and finished smooth. Long edges of
panels are tapered, allowing joints to be reinforced and concealed with a USG joint treatment system.
Sh e e t r o c k gypsum panels are available with three core types for standard construction uses.
Regular core With a regular core, available in three thicknesses for specific purposes.
1/2 Panels Recommended for single-layer application in residential construction.
3/8 Panels Lightweight, applied principally in the double-wall system over wood framing, and in repair and remodeling.
1/4 Panels Lightweight, low-cost, utility gypsum panels, used as base layer for improving sound control in double-
layer steel and wood-stud partitions, and for use over old wall and ceiling surfaces. Also for forming curved
surfaces with short radii.

Core 5/8 Type X Gypsum Panels Provide additional fire resistance over regular panels.
Fi r e c o d e C Core 1/2 and 5/8 Type C Gypsum Panels Specially formulated mineral core provides fire resistance superior to that
offered by Fi r e c o d e Core gypsum panels.
Limitations 1. Avoid exposure to sustained temperatures exceeding 125 ˚F (52 ˚C).
2. Avoid exposure to excessive, repetitive or continuous moisture before, during and after installation. Eliminate
sources of moisture immediately.
3. Non-loadbearing.
4. Fire-resistance ratings achieved when assembled in accordance with UL designs.

Painting products and systems should be used which comply with recommendations and requirements in
Appendixes of ASTM C840. For priming and decorating with paint, texture or wall covering, follow manufacturer’s
directions for materials used.
All surfaces, including applied joint compound, must be thoroughly dry, dust-free, and not glossy. Prime with
Sh e e t r o c k
First Coat primer or with an undiluted, interior latex flat paint with high-solids content. Allow to dry
before decorating.
To improve fastener concealment, where gypsum panel walls and ceilings will be subjected to severe artificial
or natural side lighting and be decorated with a gloss paint (egg shell, semi-gloss or gloss), the gypsum panel
