HOW TO INSTALL YOUR ARMSTRONG SUPENDED CEILING

Safety Tips

■ See Warning statements elsewhere on this document.

■ Work Site Environment: Initially there may be a potential adverse

impact on indoor air quality within the general work area during the

installation process. During installation, adequate ventilation of the

work area should be maintained without causing the entry of

contaminants to other parts of the building. Persons who are sensitive

to odor and or chemicals should avoid the work area during this

process.

Important Information:

■ Store and install panels in areas with a temperature range of 60° to

80°F and not more than 70% relative humidity.

■ Remove panels from the cartons 24 hours before installation and

allow them to adjust to normal interior conditions of the area where

installation will take place.

■ Never install ceiling panels below an existing ceiling that contains

imbedded radiant-heat coils.

■ Do not apply loose fill or batt insulation so that it rests directly on the

panels.

■ Keep hands clean to avoid smudges on the finished ceiling.

■ Always cut ceiling panels face up with a sharp utility knife.

■ Main beams run the opposite direction of the joists.

■ Main beams are on 4 foot centers.

■ The minimum drop is 3 inches.

■ Allow for drop-in lights by adding 2 to the height of the light for clearance.

■ Locate Hidden joists by tapping on the ceiling until you hear a solid thud.

Drive a nail in here. Repeat this to locate other joists and determine their

direction.

■ Mark the joist locations with chalklines.

1. Find joists (A).

2. Drive nails to find exact center line of joists.

3. Snap chalk line for each joist (B).

Determine Length

of Border Panels

1. Divide width of

room by length of 2

single panel *4 9

–

2. Add the remainder......1

to length of

single panel + 4

= 5

3. Divide it by 2 . . . . = 2 6

Determine Panel Layout

1. Determine length of border panels.

2. Determine width of border panels.

For best appearance, border panels

should be the same size on the

opposite sides of the room. Use your

room dimensions and follow the

formula in the worksheets at right.

THREE EASY STEPS TO INSTALL YOUR ARMSTRONG® CEILING 2ʺ x 2ʺ Installation 1. If you are using 2 x 2 panels, you need to lay out your grid differently. 2. Determine the size of your border panels from side to side. 3. Place the first main beam the border panel distance plus 2 feet from the wall. 4. Cut 4 cross tees to the wall and insert 2 cross tees between the 4 cross tees to establish the border panel openings. 5. Your main beams will then fall on 4 centers from that point.
