INSTALL CEILING PANELS

Installing Panels

• Lift panel at angle up through the grid; drop into place (A).

TIP: If there’s an obstruction in the area where you are inserting a ceiling tile,

you may need to lift the ceiling tile through an adjacent opening and gently

move it across the back of the grid into place.

• Trim border panels using a straight edge; panels should be cut face side

up (B). For tegular tiles, you will need to cut the edge that’s resting on the

wall molding to allow it to lay ﬂat.

Cutting “Tegular”/“Recessed Grid”, ceiling border panels

• Trim tegular edge border panels to the same dimensions as for ﬂat panels.

The tegular edge detail must now be cut into the panel.

• Set the panel into the grid. Draw a light pencil line on the panel using the

wall molding as a guide (C).

• Remove the panel. Use a sharp utility knife and straight edge to cut halfway

through the panel from the face side along the pencil line (D).

• Lay the utility knife on its side next to the panel and, with the panel face up,

cut in at blade height for a reveal cut (E).

• Remove the cut edge. If the cut edge of the panel is visible, paint with a ﬂat

white latex paint.

• Fit the panel into the grid.

Precautionary Measures: Precautionary Measures: During the installation be certain that the work site is well ventilated and

avoid breathing dust. Avoid contact with skin or eyes. Wear long-sleeve, loose ﬁtting clothes, gloves and eye protection. Cut and

trim with knife, razor or hand saw. Do not cut with power equipment unless either a dust collector is used on the equipment or

local exhaust is used and a NIOSH approved respirator is worn to prevent overexposure to airborne silica. Exposures to respirable

crystalline silica are not detected in industrial hygiene testing on workers installing acoustical ceiling panels for an 8 hour work

day and are not expected during the normal use of this product; however, actual levels must be determined by workplace hygiene

testing. Prolonged and repeated exposure to airborne free respirable crystalline silica can result in lung disease (i.e., silicosis) and/

or lung cancer. Panels do not release respirable dust in their installed state and therefore do not present any known health hazards

when installed and properly maintained.

First Aid Measures: If eye or skin contact occurs, ﬂush with plenty of water for at least 15 minutes and remove contaminated

clothing. After installing material, wash with warm water and mild soap.
