3. ACCESSORIES FOR USE WITH ACOUSTAFFIX
™
PANELS
3.1 Fasteners
Armstrong Ceilings provides installers with two types of fasteners. Use the
All-in-one Self-stop Fastener, described in Section 3.2, for direct mounting to
furring or drywall grid. Use the Truss Mounting Kit, described in Section 3.3,
for mounting to trusses.
System performance is based on using the appropriate fastener at the correct
spacing. Armstrong Ceilings does not warrant the use of any other types of
fasteners for AcoustAffix installations.
3.2 All-in-one Self-stop Fastener
All-in-one Self-stop fasteners (illus. 3.2) are designed to stop as soon as
their collars come in contact with furring or drywall grid, thereby allowing the
head of the screw to rest snug against the face of the panel without the risk
of countersinking. The same fastener is used for Armstrong
®
Drywall Grid or
20- to 25-gauge furring channel, or wood furring. The screw’s oversized head
acts as a built-in washer once properly installed.
3.3 Truss Mounting Kit
The Truss Mounting Kit contains threaded rod and weld nuts (illus. 3.3).
The threaded rod is designed to pierce panels and be capped on both ends
by the weld nut. The weld nut’s head acts as a washer once properly installed.
Each kit contains 15 threaded rods and 30 weld nuts. See Section 7 for
installation steps.
3.4 QSUTC (QuickStix Uptight Clip)
Installations using Armstrong Drywall Grid require the QSUTC for attachment to
deck or wall (illus. 3.4). The minimum distance from the deck or wall to the face
of grid when using the QSUTC is 1-3/4" and can adjust up to 5-1/2" to account
for unevenness in the surface.
• Each QSUTC requires secure attachment to structure (specified by contractor
based on deck material) and two framing screw attachments from the clip to
the grid.
For Flat Installations:
• Each 12' main beam requires 3 QSUTC attachments to deck spaced no further
than 6' O.C.
• All drywall mains must have a QSUTC attachment within 12" of each and within
3" of the fire expansion notch
See Section 11.1 for attachment spacing requirements for sloped and wall installations.
3.5 Direct Apply Accessories
The recommended adhesive for direct apply panel installations is Titebond
®
GREENchoice Acoustical Ceiling Tile Adhesive.
See Section 8 for further information.
