SAFETY TIPS:

• Safety glasses and gloves are recommended to be worn during installation. Metal grid components can be sharp.

• When working overhead, make sure your work area is clear of obstructions and that your ladder is stable.

IMPORTANT INFORMATION:

• Store and install panels in areas with temperature and humidity ranges that meet specific product warranty

requirements.

• 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 embedded radiant-heat coils.

• Do not apply loose fill or bat insulation so that it rests directly on the panels.

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

• Always cut mineral fiber or fiberglass ceiling panels face up with a sharp utility knife.

• Main beams should be installed perpendicular to the joists.

• Main beams are typically installed on 4' centers. If your room configuration is unusual, you may require additional

components.

• To allow for ceiling tile installation and accessibility, the minimum drop is 3" with traditional hanger wire or 2.5" with

QuickHang

™

grid hooks. (QuickHang instructions are notated by a gray background)

NOTE: QuickHang hooks and brackets are available through select retailers. Visit ceilings.com/stores for where to buy.

• Installations with light fixtures will likely require additional clearance and support. Consult the light manufacturer’s

instructions for details.

• When installing below an existing drywall ceiling, a minimum 4" drop is required to install panels. Joists will need to be

located and marked.

NOTE: QuickHang hardware cannot be used below drywall ceilings.

TOOLS NEEDED TO INSTALL YOUR CEILING

PLANNING YOUR ARMSTRONG CEILING

Main beams typically run perpendicular to the joists. If you have an

existing drywall ceiling you will need to locate and identify the joist

direction.

LOCATE HIDDEN JOISTS TO INSTALL WIRE FASTENERS

Use either a stud finder or 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

chalk lines.

• Find joists (A).

• Drive nails to find exact center line of joists.

• Snap chalk line for each joist (B).

How to Install Your Armstrong® Suspended Ceiling Traditional Hanger Wire • Snap Chalk Line for Main Beams 4' Apart (A). • Screw in Wire Fasteners 4' Apart (B). • Wrap hanger wire securely around itself 3 times (C). NOTE: Additional hanger wires may be needed to support light fixtures. • Measure up 7/8" from the bottom of the molding. Drive nail into wall just above molding. Do the same on other side of room. Stretch a string from nail to nail along a row of wires (D).

(This creates the proper border tile opening.) TIP: Cut the top of the grid first with tin snips and then bend the grid open and cut the face of the grid (A).
