Installing Armstrong Suspended Ceilings
An Armstrong suspended
mineral fiber ceiling is
functional, attractive and
provides easy access to the
plenum. This ceiling system
installation brochure is
intended as a general
application overview,
covering essential steps of
a basic suspended ceiling
installation.
The ceiling system is made up of Armstrong
panels (either 2′ x 4′ or 2′ x 2′) which are
supported by a suspension system (main
beams, cross tees
and hangers), and
perimeter molding.
The integrity of the
entire suspended
ceiling depends on
the hangers –
commonly wires –
Armstrong Ceiling System
which are used
to support the
suspension system main beams. Sections of
main beams are spliced together and are
connected by cross tees. The ends of the main
beams and cross tees rest on the wall molding
which runs around the perimeter of the space.
Before You Start
Although temperature and humidity
recommendations vary by product, the space
must be cleared of debris and, in general,
should be enclosed.
• The ceiling panels should be kept clean, dry,
and protected from the elements. Panels
should be removed from cartons 24 hours
before installation to allow them to adjust to
interior conditions.
2
• The tools you will need will vary depending
on the type of hangers used, but generally,
you will need: ladders or scaffolding; a tape
measure; pencil; chalk line; hammer; powderactuated fastener; awl; pop-rivet gun; screw
driver or drill; sheet metal punch; aviation
snips; wire cutting pliers; utility knife; level
(water level or laser); string; key hole saw;
and compass or dividers. Most jobsites also
require some safety equipment like a hard hat
or safety glasses.
Determine Panel Direction
• Ceiling panels can run in the direction
that yields the most pleasing finished
appearance.
• In spaces with bar or wood joists, main
beams must be oriented perpendicular to
the joists. (You must locate and mark all
joists if they have been covered with a
drywall ceiling.)
Main beams must be
oriented perpendicular to
bar or wood joists
Determine Border Panel Sizes
(2′ X 2′ panels)
• To determine the border panel sizes, divide
one dimension of the space by 2′.
• Our example shows a space that is 10′ 8″
by 14′ 2″ and the deck joists run in the
10′ 8″ direction. 10′ 8″ ÷ 2′ = five full
panels + remaining 8″.
• You can’t start with a full panel against one
wall and leave one 8″ border on the other
semi side; it will look unbalanced (and two
border panels of 4″ would be too small).
So, add 24″ to the 8″ dimension, which
equals 32″. Divide that number by 2 to
equal 16″.
• The room would be divided into four full
panels, plus two 16″ border panels.
32" ÷ 2' =
Four full panels plus
two 16" border panels
Determine width of border
panels (2 ′ x 2 ′ panels)
26" ÷ 2' =
Six panels plus two
13" border panels
Determine width of border
panels (2 ′ x 2 ′ panels)
• In the other direction: 14′ 2″ ÷ 2′ = seven
panels + remaining 2″.
• Add 24″ to the 2″ dimension, which equals
26″. Divide that number by 2 to equal 13″.
• This side of the room would have six full
panels and two 13″ border panels.
3
Determine Border Panel Sizes
(2′ X 4′ panels)
74" ÷ 2 = 37"
Two full panels plus
two 37" border panels
Determine width of border
panels (2′ x 4′ panels)
• For 2′ x 4′ panels, divide one room
dimension by 2′ as stated above.
• Divide the other room dimension by 4′ and
add 48″ to remaining dimensions to avoid
unsightly small border panels.
Install Perimeter Trim
• Allow at least three inches below the old
ceiling, ducts, pipes or wiring as clearance
to maneuver a lay-in panel into the opening
of the grid.
• Mark the desired height for the new ceiling,
adding the height of the wall molding. Mark
a level line around all three walls and snap
a connecting chalk line on the fourth wall.
Mark desired height
for new ceiling
4
• Attach the molding securely. Screws or
6d (1-1/2″) nails work well for wood; use
screws for metal; use powder-actuated
fasteners or expanding anchors for
concrete and stone walls. Joints between
inside and outside corners of molding
must be tight.
Install Hangers and Fasteners
• Hangers need to be installed above the
main beams typically every four feet.
• Snap a chalk line for each of the main
beams. Attach hangers and wires to the
deck above the first row of main beams
at four-foot intervals.
• Stretch a guide string from one end of
the room to the other, below the molding
where the first main beam will hang.
• Stretch a leveling string from one side
to the other 7/8″ above the bottom of the
wall molding.
• Bend the wires at the height of the string
so that the main beam is held at the
correct height.
Bend hanger wires at height
of guide string
• Wrap hanger wire securely around itself
three times.
Install the First Main Beam
• Install the first section of main beam.
(Cut the end so that a cross tee route hole
is located the border distance in from the
end wall.)
• Insert a hanger wire into a hanger wire
hole near the other end of the main beam.
Bend the wire up and wrap it around itself
three times. Continue to insert all other
hanger wires.
Install first main beam
5
Install Border Cross Tees
• Find the location of the first border cross tee.
Install border cross tees
• Place the end of the white face of the cross
tee against the edge of the wall molding at
the side, and cut the cross tee where it
crosses the guide string.
• Insert the uncut end of the cross tee into the
main beam, and rest the cut end of the cross
tee on the molding. (The far edge of the main
beam should be directly above the string.)
• Repeat the process for the next cross tee.
• Temporarily fasten the cross tees to the
wall molding so they do not move.
Square the Grid
• Join additional sections of main beam as
required to reach the other end wall. Attach
hangers and check level as the installation
proceeds.
Join sections of main beam
• Use leftover piece of main beam from the
first row to start the next row.
• Install two four-foot cross tees between the
two main beams, in line with the first two
border cross tees.
Square the grid by measuring
across the diagonal of
the grid opening
6
• Measure across the diagonals of the 2′ x 4′
opening. The measurements will be the
same if the grid is square. If the grid is not
square, shorten one of the main beams
until the diagonals are equal.
Install Remaining Main Beams
and Cross Tees
• Complete the installation of rows of main
beams.
• Note: If you have additional rows of main
beams to install, stretch a second string from
one side of the room to the other, aligning it
with the first four-foot cross tee as shown.
Align second guide string
with first four-foot cross tee
• This second string will be your guide for
cutting the remaining rows of main beams.
Just measure from the end wall to the
string to determine the distance for the
first cross tee slot you will use.
• You must line up all cross tee slots for the
grid to be square.
Install Panels
• Slightly tilt panels, lift above framework,
and gently rest on cross tee and main
beam edges.
• Measure and cut border panels individually.
Using a leftover cross tee or main beam
section as a straight edge, cut panels face
up with a very sharp utility knife. Border
panels may require field cutting of Tegular
edge details. All field cut edges “exposed to
view” should be colored to match the factory
finish. Armstrong SuperCoat™ Ceiling
Panel Touch-up Paint is recommended.
Lighting and Other Fixtures
Tilt panels above frame and
drop into place
Tegular-edge border panels
may require field cutting. Cut
border panels face up
Lighting and other fixtures must be
supported by the grid, not by the ceiling
panels. Depending on the size and weight of
the fixtures, extra hangers may be required.

Quick Links:
Acoustical Performance Terms
Application Standards
Suspension System Terms
Access Hook – Used in concealed tee system to support a row
of tile to be installed in a 4' x 4' module that also allows access
to the plenum above. Also called Saddle Spline.
Fire Performance Terms
General Terms
Light Reflectance Terms
Suspension System Terms
Breather Spline – Spline used to link tiles in a concealed tee
installation and to prevent air infiltration.
Bulb – The upper ridge of the main runner or cross tee with a
rectangular, triangular or round configuration. Adds structural
load strength to the component.
Cap – The rolled covering on the flange of a T-Bar. T-Bars
come with an aluminum or steel cap and in many colors.
Ceiling Suspension System – A system of metal members,
designed to support a suspended ceiling, typically an acoustical
ceiling. Also may be designed to accommodate lighting fixtures
or air diffusers.
Clips – Several clip designs are available to suit applications
such as fire resistance, wind uplift and impact. Fire-resistance
rated designs have exact requirements, including the mandatory
use of hold down clips for acoustical panels or tiles weighing
less than 4.9 kg/m2 (1.0 pound per square foot). For rooms with
significant air pressure differential from adjacent spaces,
retention clips may be necessary to retain panels in place.
Maintaining air pressure values may also require perimeter
panel seals, typically a closed cell foam gasket with adhesive on
one side.
Concealed Mounting System – Tile suspension system using
T-Bars and splines which fit into kerfs cut into tile edges. Unlike
exposed-grid systems, concealed mounting systems are not
visible from below the ceiling. Inverted tee, "H and T," or "Z"
profile grids are common for these applications with provisions
for full plenum access usually incorporated into the grid design.
Cross Runner, Cross Tee – The cross runner is the secondary
or cross beams of a mechanical ceiling suspension system,
usually supporting only the acoustical tile. The cross tee is
inserted into the main runner to form different module sizes. In
some suspension systems, however, the cross runners also
provide support for lighting fixtures, air diffusers and other cross
runners.
Deflection – Bending or deviation from a straight line or course.
Used here as the standard by which allowable load for
suspension system components is measured.
Double Web – Indicates two layers of material in the
http://www.armstrong.com/commceilingsna/article22392.html
6/4/2015
Ceiling and Suspension System Glossary - Armstrong
Page 2 of 5
construction of the vertical web of main runners and cross tees.
Downward Access System – Direct access is achieved by
removing individual units by hand or may require an access clip
or key. Multiple panels designed as end- or side-pivoting units
can also be used. The number of permissible access openings
are fewer with an end pivot design. Downward access may be
desirable if tight plenum clearance is a problem. In fire-rated
designs, the amount of each access area and pan size is
governed by testing criteria.
Duty Classification – Load carrying capability of grid main
beams (per ASTM C635) pounds per lineal foot (Light: 5 lbs;
Intermediate: 12 lbs; Heavy: 16 lbs).
Electrogalvanized – A plating process that deposits a coating
of zinc on a cold rolled steel substrate. Thickness or weight of
coating can be varied and is typically categorized as heavyelectro through standard-electro or "flash" electrogalvanized.
Process providing rust resistance for metal.
Environmental Systems – Grid systems that are made of base
materials that withstand a variety of moist and corrosive
conditions.
Exposed Grid System – Structural suspension system for layin ceiling panels. Factory-painted supporting members are
exposed to view. Exposed tee surfaces may be continuous or
have an integral reveal. Reveals are typically formed as channel
or rail profiles extending down from the tee leg. Bolt-slot type
reveal designs can accommodate partition attachment. The
choice may be restricted by appropriate tee width for panel
selected and limitations on available panel edge details for the
chosen grid profile.
Fixture Weight – Individual weight of mechanical services
supported by ceiling grid members.
Flange – Horizontal surface on the face of the tee, visible from
below the ceiling. The part of the grid to which the color cap is
applied. Most grid system flanges are either 15/16″or 9/16″.
Galvanized – A generic term used to describe a sheet or coil of
steel coated with zinc applied in an electrogalvanizing or dipping
process.
Gasketed Grid – Ceiling suspension system that has a
gasketing attached to the top side of the flanges. Used in clean
room ceilings to seal the panels to the grid.
Gauge – Thickness of the steel used to make a grid member.
May be expressed by a number designation (26 GA.) or in
thousandths of an inch (0.013).
Grid – Structural system of main beams, cross tees, and
associated hardware which hangs from the deck above and
supports lay-in, concealed or surface attached ceiling panels.
Hanger Wires – Wire employed to suspend the acoustical
ceiling from the existing structure. The standard material is 2.05
mm (12 gauge) galvanized, soft annealed steel wire, conforming
to ASTM A 641M or A 641. Heavier gauge wire is available for
higher load carrying installations, or situations where hanger
wire spacing exceeds 1200 mm (4 feet) on center. Stainless
steel wire and nickel-copper alloy wire are frequently used in
severe environment designs. Seismic designs or exterior
http://www.armstrong.com/commceilingsna/article22392.html

Ceiling and Suspension System Glossary - Armstrong
Page 3 of 5
installations subject to wind uplift may require supplemental
bracing or substantial hanger devices such as metal straps,
rods or structural angles.
Heavy-Duty Systems – Primarily used for installations in which
the quantities and weights of ceiling fixtures (lights, air diffusers,
etc.) are greater than those for an ordinary commercial
structure.
Hold Down Clip – Mechanical fastener that snaps over the bulb
of a grid system to hold ceiling panels in place.
Hook Tee – Cross tee with an end tab that hooks through the
rout hole and rests on the vertical web of the main runner.
Hot Dipped Galvanized – Process to coat steel to offer
environmental resistance to corrosion. Cold rolled steel is
submerged (dipped) into a molten zinc bath. A heavy coating of
zinc is applied to the steel substrate. Zinc coating thickness
varies and is designated by a "G" series, such as G-60 or G-90.
Integral Splice – Connects the mains or tees together and is
formed from the base metal of the components.
Intermediate-Duty Systems – These are used primarily for
ordinary commercial structures where some ceiling loads, due
to light fixtures and air diffusers, are anticipated.
L/360, Span/360 – The distance between support points of a
suspension system member divided by 360. The result of this
mathematical equation is the maximum amount of deflection
that is allowed under ASTM C 636.
Light-Duty Systems – Used primarily for residential and light
commercial structures where ceiling loads other than acoustical
tile or lay-in panels are not anticipated.
Load – Amount of force (weight) that is applied to a lineal foot of
any load bearing member of a ceiling system.
Main Beam, Main Runner, Main Tee – Primary or main beams
of the type of ceiling suspension system in which the structural
members are mechanically locked together. Provide direct
support for cross runners and may support lighting fixtures and
air diffusers, as well as the acoustical tile. Supported by hanger
wires attached directly to the existing structure; or installed
perpendicular to carrying channels and supported by specially
designed sheet metal or wire clips attached to the carrying
channels. Typically a 12′piece located 4' on center.
ML – Cross tee end detail that is a "hook" insertion contrasted
with the XL that is "stab" insertion. The ML end detail is quick
and easy to install; however, it does not meet most seismic
requirements greater than IBC Seismic Design Category C.
Override – Offset on the end of some cross tees that rests on
top of the supporting member’s flange. Increases stability and
moves cut edge of tee out of the visible plane of the ceiling.
PeakForm – An improvement in the main beam bulb design
from a rectangular shape to one that culminates to a point, or
peak. Unique profile increases strength and stability of grid
during installation.
Rotary Stitching – Process by which two vertical layers (double
http://www.armstrong.com/commceilingsna/article22392.html
6/4/2015
Ceiling and Suspension System Glossary - Armstrong
Page 4 of 5
web) of steel are stitched or bonded together to form a more
homogeneous component exhibiting increased column strength,
torsional strength and overall handleability. Armstrong is the
only grid manufacturer to employ this technology.
Semi-Concealed Installation System – Installation system in
which tile kerfs are shallow enough to leave gaps between the
tiles in one direction, exposing the grid on two sides. Usually an
inverted grid. Two opposing panel edges are fabricated for a
concealed grid profile.
Seismic Compression/Tension – The capability of a grid
member connection to carry a mean ultimate test load in
compression/tension.
Shadow Molding – A W-shaped molding that will produce a
reveal or space between the ceiling and the wall when fastened
to the wall.
Slotted Systems – Either bolt-slot or screw-slot systems, both
of which offer a dimensional look to an otherwise flush ceiling
using 9/16″exposed components. Typically feature a 1/8″or 1/4″
groove that runs down the center of the components.
Spline – A strip of metal or fiber inserted in the kerfs of adjacent
acoustical tile to form a concealed mechanical joint seal.
Stab End Detail – Provides a tee to tee lock. Designed to be
inserted with a forward motion.
Stabilizer Bar – U-shaped channel, either 24′long or 48′long,
designed to maintain cross tee spacing at the perimeter. Used
in seismic installations to help prevent cross tees and panels
from falling from the suspension system during an earthquake.
Stiffening Brace – Used to prevent uplift of grid caused by
wind pressure in exterior applications.
Stitching – Dimples impressed in grid members to knit the
webs together. (See Rotary Stitching)
Superlock – Main beam end detail that is a staked-on clip to
splice main beams together. This clip provides a strong, secure
connection that is easy to remove and relocate.
Suspension System – A metal grid suspended from hanger
rods or wires, consisting of main beams and cross tees, clips,
splines and other hardware which supports lay-in acoustical
panels or tiles. The completed ceiling forms a barrier to sound,
heat and fire. It also absorbs in-room sound and hides ductwork
and wiring in the plenum.
T-Bar – Any metal member of "T" cross section used in ceiling
suspension systems.
UL 580 – Wind uplift test (Class 15 – 15 lbs/sf; Class 90 – 90
lbs/sf).
Wind Uplift – Resistance to wind uplift forces may be
necessary for exterior
ceiling and soffit designs. A substantial hanger system design,
incorporating rods or straps, plus acoustical unit retention clips,
is commonly required. Verify code requirements for wind uplift
force resistance and manufacturer’s recommendations for
ceiling installations based on these values.

Tectum Acoustical Walls
Tectum Interior Wall Panels offer an
effective, permanent and attractive
solution for any kind of activity that
produces undesirable noise levels
within an enclosed space. They are
abuse resistant and are able to
withstand the impact of thrown or
kicked balls in gyms, yet are
lightweight.
Tectum acoustical wall panels are
easy to install in new construction
and in existing buildings for effective
sound control. Up to 1.00 NRC can be
achieved. Furring strips installed
horizontally (when using vertical
panels) are recommended and should
be a maximum of 24” o.c. when using
1” thick panels.
SIZES, FINISHES
Tectum Interior Wall Panels are
available 1”, 1 1⁄2” and 2” thick in widths
of 23 3⁄4”, 31 3⁄4” and 47 3⁄4” with long
edges beveled. 1 1⁄2” and 2” panels are
also available with T&G edges in
widths of 23”, 31” and 47” for
interlocking continuous paneling. All
panels are available in 48” - 144”
lengths and are field machinable.
Factory finish is in natural, painted
white or custom colors and can easily
be field painted without losing their
acoustical efficiency.

ENVIRONMENTAL INFORMATION
The wood fibers (excelsior) used in
Tectum panels come from Wisconsin
Aspen trees. The Wisconsin Aspen is
a self-propagating type tree. When
cut, a new tree will begin to grow
back from its root structure. In
addition, all Wisconsin Aspen used
for Tectum is air-dried. No drying
kilns are used. The wood is stored in
ranks to age naturally. No chemicals
are used in the production of any
excelsior purchased by Tectum Inc.
All excelsior used in Tectum
products comes from a single source
that is affiliated with both the Forest
Stewardship Council (FSC) and the
Sustainable Forestry Initiatives (SFI)
programs. These programs are a
comprehensive system of objectives
and performance measures that
integrate the perpetual growing and
harvesting of trees with the
protection of wildlife, plants, soil and
water quality. All loggers are trained
to adhere to FSC and SFI principles.
Magnesium oxide is mixed with
magnesium sulfate (Epsom salts) to
form the primary binder. The
magnesium sulfate solution has
been manufactured on site by
reclaiming waste materials since
production began in 1949. The
secondary binder is composed of
sodium silicate and calcium
carbonate (limestone). All of the
water used in the manufacture of
Tectum is captured and recycled.
