Wallboard and Metal Partition Installation Guide

Wallboard Application

• Horizontal wallboard: Screws spaced no more than 12 inches apart in the field and along abutting joints.
• Vertical wallboard (fire rating): Screws spaced at 12 inches in the field and 8 inches along vertical abutting edges (2-hour fire rating).
• Fastening: Fasten wallboard to floor and ceiling track with one screw midway between vertical stud flange.
• Screw heads: Should slightly depress the wallboard surface.
• Placement from edges/ends: Screws should be driven at least 2 inches from edges/ends.
• Corner beading/trim: Easily applied using electrical screw guns and appropriate fasteners.
• Ceilings: Studs used as joints on top of track, at 24-inch intervals. Provide backing at the plate line. Wallboard applied on joists with drywall screws.

Metal Partition Procedure

• Building in open areas: Erecting partition on the floor before raising it to ceiling.
• Assembling procedure:
  • Complete wall assembling on floor.
  • Raise, position, fasten to intersecting/abutting walls.
  • Plumb doors & walls, fasten floor track.

Selection of Metal-Stud Partitions for Sound and Fire Control

• Sound Control: Careful selection of well-tested partitions important.
• Preventing flames from reaching studs: Primary design concern for fire control.
• Factor variables (fire protection): Type of wallboard & number of layers needed to maintain a fire for a pre-determined length of time.

Control of Sound

• Assessing Sound Control Function: Factors include area noise level, other side's noise level, and absorption loss during transmission.
• Noise leaks/vibrations: Can compromise control planning (tiny openings can significantly reduce sound blocking).
• Sound reduction through doors: An ordinary slab door reduces sound transmission by about 10 decibels; even more so when weather stripping is added.
