Cutting Panels

–

Cut ends, edges, scribe, and make cutouts within fields of panels in a workmanlike manner. Panels should be
cut to size utilizing a knife and straight edge. A power saw should be used only if it is equipped with a dust-
collection device. Panels may be cut by scoring and snapping, or by sawing, working from the face side.

Brand Panels may also be used.

–

When using the score-and-snap method, score the panel twice and snap the panel away from the cut face.
The backside of the panel is then broken by snapping the panel in the reverse direction.

–

If a power-operated saw is used, a low-RPM, 3-1/2

Љ (89 mm) carbide-blade, portable saw is recommended.

–

Where necessary to obtain neatly fitting joints, a rasp or surform should be used to smooth cut edges.

–

Holes for pipes, fixtures, and other small openings can be cut out with a saw or a drywall router equipped with a

1/4

Љ carbide bit.When using a router, panels should be held away from the wall to avoid damage to utility boxes.

Basic Single-Layer System

Position all ends and edges of all gypsum fiber panels over framing members, except when joints are at right

Treated Joints

angles to framing members, as in perpendicular application or when end joints are back-blocked.

Apply gypsum fiber panels first to the ceiling, then to the walls. Install panels vertically whenever possible. For horizon-
tal panel application, panels must be gapped 1/16" of an inch. End joints should be loosely fit. Install panels a minimum
of 3/8" above the floor. To minimize end joints, use panels of maximum practical lengths. Stagger end joints in succes-
sive courses with joints on opposite sides of a partition placed on different studs.

Attach panels to framing supports by: (Standard Single Nailing Method) (Double Nailing Method) (Power-Driven
Screws). Space fasteners not less than 3/8

Љ from edges and ends of panels and drive as recommended for

specified fastening method. Drive fasteners in field of panels first, working toward ends and edges. Hold panel
in firm contact with framing while driving fasteners. Drive fastener heads slightly below surface of gypsum fiber
panels in a uniform dimple.

For non-fire-rated partition designs, refer to the table below for fastener spacing. For UL fire-rated partition
designs, refer to the specific UL design for proper fastener spacing.

surfaces. Apply metal or paper-faced corner bead to all vertical or horizontal external corners in accordance
with manufacturer’s directions.
