EXAMINATION
A.
Do not begin installation until substrates have been properly prepared.
B.
If substrate preparation is the responsibility of another installer, notify Architect of
unsatisfactory preparation before proceeding.
C.
Verify that all rough-in utilities are located properly.
PREPARATION
A.
Clean surfaces thoroughly prior to installation.
B.
Prepare attachment surfaces so they are plumb, level and in proper alignment for accepting
the cold formed framing members. Prepare surfaces using the methods recommended by
the manufacturer for achieving the best result for the substrate under the project conditions.
FABRICATION
A.
Prior to fabrication of framing, submit shop drawings to the architect or engineer to obtain
approval.
B.
Framing components may be preassembled into panels prior to erecting. Prefabricate
panels so they are square, with components attached in a manner which prevents racking
and minimizes distortion during lifting and transport.
C.
Fabrication Instructions:
1.
Cut all framing components square for attachment to perpendicular members or as
required for an angular fit against abutting members.
2.
Plumb, align and securely attach studs to flanges of both upper and lower runners,
except that in the case of interior, non-load bearing walls where studs need not be
attached to upper or lower runners.
3.
In all doubled jamb studs and doubled headers not accessible to insulation
contractors, provide insulation equal to that specified elsewhere.
4.
Splices in members other than top and bottom runner track are not permitted.
5.
Provide temporary bracing where required, until erection is complete.
6.
Handling and lifting of pre-fabricated panels shall be done in a manner so as not to
cause distortion in any manner.

shaft side with an approved fastener.
3.
Apply non-hardening, flexible sealant in a continuous application at the perimeter.
4.
Space C-T Studs at 24 inches O.C. Plan the spacing at ends of Shaft Wall
construction so end studs are minimum 12 inches from the ends.
5.
Install the first Liner Board panel. The panel length shall be 3/4 inch less than the total
height of the framed section. Plumb the panel against the web of the Tabbed Track
and bend out tabs in Tabbed J-Track to secure the panel in place.
6.
Cut C-T Studs 1/2" less than overall Wall Height.
7.
Insert C-T Stud into the top and bottom Tabbed Track and fit tightly over the
previously installed 1 inch panel. Allow equal clearance between track and stud at top
and bottom J-Track.
8.
Install the following 1 inch Liner Board panel inside the Tabbed J-Track and within the
tabs of the CT Studs.
9.
Install the remaining C-T studs and Liner Board panels in the same manner previously
described above until the wall section is complete.
10.
Install the final panel section at 12 inches O.C. utilizing the tabs of the Tabbed JTrack to secure the panel.
11.
Where wall heights exceed the standard or available length of the Shaftwall Liner
Board panels, the liner panels can be cut and stacked with joints occurring within the
top or bottom third points of the wall height. Note: The shorter panels shall be
minimum 24 inches long and of sufficient length to engage 2 studs. Note: Joints of
adjacent panels should be staggered to avoid continuous horizontal joint,
12.
For doors, ducts or other large penetrations or openings, install Jamb Strut as
perimeter framing. Use 20-gauge track with a 3 inch back leg for elevator doors and
block cavity. Install 12 inch wide gypsum filler strips for doors exceeding 7 foot height..
