Ceilume Installation Instructions | Revised September 2016

Storing
Store boxes of tiles upright in a single layer (no stacking) in a cool spot out of direct sunlight.
Fire Sprinklers
When re suppression sprinklers are involved with your drop ceiling installation, your rst and most
important step is to consult with your local building and re ocials to make sure that your intended
use will conform with the appropriate local codes.
Sprinklers Penetrating Ceiling Panels
Ceilume’s ceiling panels and tiles are designed to be sensitive to heat from a re; that is why they
can be used as drop-out ceiling panels (see next section). When a re suppression sprinkler passes
through a tile, the tile cannot interfere with sprinkler operation in the event of a re.
When it is necessary for your sprinklers to penetrate/pass through your ceiling tiles and be visible in
the room, you must…
Cut the opening in the ceiling tile a minimum of 0.25” larger than the outer diameter of the
sprinkler head or trim ring/escutcheon (whichever is larger). This enables the tile to fall
from the ceiling grid without becoming entangled with the sprinkler or interfering with its
operation.
or
Use a 0.030” thick Signature Ceiling Tile backed by a mineral ber ceiling panel at each
sprinkler penetration. This holds the tile in place and keeps it insulated, preventing it from
interfering with sprinkler operation.
Never use a restraining-type trim ring/escutcheon at a sprinkler penetration without an
appropriately sized tile opening or mineral ber ceiling tile backer.
Drop-Out Ceiling Panels Beneath Sprinklers
All of Ceilume’s ceiling panels and tiles are approved for installation beneath re sprinklers in Light
Hazard and Ordinary Hazard Group I occupancies. When exposed to heat from a developing re,
drop-out ceiling panels soften, distort, and fall from the ceiling grid. Heat from the growing re
activates the sprinkler which, unimpeded by the panels, controls or extinguishes the re.
