These lightweight, fire and sound-resistant assemblies consist of one
or two layers of SHEETROCK Brand Gypsum Panels screw-attached to
steel framing. A specially designed self-tapping steel screw with a rust
inhibitive coating is used to attach the panels to the framing. The
systems are completed with a U.S.G. joint system and decorating-
both steps unnecessary in walls when predecorated vinyl-surfaced
TEXTONE Gypsum Panels are used.
Gypsum panels for these assemblies are available in three thick-
nesses and seven types (see Specifications). Systems using
SHEETROCK Brand FIRECODE and FIRECODE "C" Gypsum Panels, with a
specially formulated core, obtain higher fire ratings than regular gyp-
sum panels (see table page 2). These versatile panels are applied to
USG Steel Studs or Metal Furring Channels to meet design require-
ments for fixed interior partitions-divider, corridor, party and chase
walls; furred and suspended ceilings; wall furring and column firep-
roofing, as outlined below:

cations, page 16) and cut to lengths required for the job. Double-layer
/2" SHEETROCK Brand FIRECODE "C" Panels attached to 21/2" or 3W
studs spaced 24" o.c. provide a 2-hour fire rating plus sound control
suitable for party walls. Multi-layer V2 SHEETROCK Brand FIRECODE "C"
Panel assemblies offer 3- and 4-hour fire ratings and up to 62 STC
sound control, yet are much lighter weight and thinner than concrete
block. These assemblies also provide a 3-hour fire-resistant enclosure
for steel trusses in staggered truss systems. Where added partition
width is required, double rows of studs are erected to provide chase
walls with up to 2034" net pipe chase width (see page 7).
Shaft Walls-Gypsum panels, assembled with gypsum shaft wall
liner and specially shaped C-H Studs, offer systems ideally suited for
enclosing elevator shafts, stairwells and other vertical shafts in core
areas of multi-story buildings (see separate Shaft Wall Folder SA-922

tion (see page 13). The systems are also suitable for separate beam
protection and for exterior ceilings and soffits with USG Exterior Gyp-
sum Ceiling Board facings.
3. Wall Furring-With Foil-Back Gypsum Panels screwed to USG
Metal Furring Channels, this construction provides an excellent vapor
retarder as exteriorwall furring (see page 10). Panel application to USG
Z-Furring Channels with semi-rigid insulation provides afully insulated
wall at a cost competitive with many non-insulated furred walls.
4. Column Freproofing-SHEETROCK Brand FIRECODE "C" Panels
screw-attached to steel studs at column comers and finished with
comer bead and joint compound, offer lightweight, compact fire pro-
tection for steel columns (see page 9).
function and utility
Adaptable to virtually every type of new construction-commercial,
institutional, industrial and residential-or in modernization to provide
smooth, durable interior surfaces.
Fire Resistant-Constructed of noncombustible components. Es-
tablished fire ratings available to meet design requirements; partitions
up to 4 hours, ceilings up to 3 hours including beam, column fireproof-
ing up to 4 hours.
Sound Isolatlon-STC ratings up to 62 for multi-layer, 55 for double-
layer and 48 for single-layer partitions; 54 for single-layer ceilings.
THERMAFIBER Sound Attenuation Fire Blankets improve sound control.
Lightweight-These thin, drywall assemblies weigh only 5 to 17 psf,
reduce dead load and save floor area.
Economical-Low material cost and speed of erection provide
realistic and competitive construction costs.
1. Non-load bearing.
2. Exposure to excessive or continuous moisture and extreme tem-
peratures should be avoided.
3. Maximum frame spacing is 24" o.c., except when single-layer ceil-
ing panels are applied with long edges parallel to joists and used as a
base for spray-applied texture finish, max. frame spacing is 16" o.c.
4. In ceiling design, certain precautions concerning construction,
isolation and ventilation are necessary for good performance (see
_S~gcifications, page 16).
