ceiling domes installation for new contraction
1. Ceiling domes MUST be installed before ceiling wallboard is installed
with the option of installing ceiling domes up into ceiling joist or below
joist
2. It is highly recommended that ceiling domes installation be preplanned
with ceiling domes frame-out below joists included on blueprints
3. If installing ceiling domes onto ceiling joists is highly recommended
that you consult a construction engineer before you can cut into ceiling
joists, to insure that the load bearing properties of ceiling joists are not
compromised
4. Installing Below Joists Option: Skip next step
5. Cutting Joist Option: Cut out necessary ceiling joists. Note: You may not
need to remove all joists depending upon dome depth. Cut and install double
supporting joists perpendicular to ceiling joist and install framing members
parallel to ceiling joist. Shim out framing to ensure snug fit of dome [A &
B]
6. Ceiling domes have hanger strips attached to back. On overhead joists,
install wood screws over hanger strips of dome, leave -1/2" of screw head from
the joist. Using construction wire, thread wire through hanger strips on
dome and attach to screws installed on joist. Make sure dome is level [C]
and secure
7. Install ceiling board. Cut the board around dome leaving approximately 3”
of ceiling board above the dome edges. Rimless 8. ceiling domes may be
finished out using standard drywall finishing methods
8. Apply electrometric adhesive caulk around ceiling domes edge, smooth
excess adhesive/caulk around dome edge with your finger or putty knife [D].
Wipe off any excess adhesive/caulk with damp sponge
9. Finish ceiling domes using a high-quality latex or oil-based paint
ceiling domes installation for tray ceiling or high ceiling
1. Ceiling Domes have hanger strips attached to back. On overhead joists,
install heavy-duty wood screws eyes over hanger strips of dome. Using
construction wire, thread wire through hanger strips on dome and attach to
screws installed on joist. Make sure dome is level [C]
2. Frame out ceiling to existing ceiling joists using standard ceiling
construction practices
3. Install ceiling board. Cut the ceiling board to the rough opening [inside
diameter] of the dome. Rimless ceiling domes may be finished out using
standard drywall finishing methods
4. Apply elastomeric adhesive caulk around the ceiling domes edge, smooth
excess adhesive/caulk around dome edge with your 5. Finish ceiling domes
using a high-quality latex or oil-based paint
ceiling domes installation for lay-in or suspended ceiling
1. Make a template as described in "Surface Preparation". DO NOT MARK OR CUT
THE EXTRA 3" FOR ROUGH OPENING - CUT TEMPLATE TO EXACT DOME SIZE. Tape
template to installation area and trace outline onto ceiling
2. Cut through acoustical tiles with jig or saber saw, and metal framing
using a hacksaw [F]
3. Ceiling domes have hanger strips attached to back. On overhead joists,
install wood screws over hanger strips of dome, leave -1/2" of screw head from
joist. Using construction wire through hanger strips on dome and attach to
screws installed on joists [C].
4. Finish ceiling domes using a high-quality latex or oil-based paint
ceiling domes installation when used with electrical lighting fixture
1. Follow instructions above for appropriate installation application in
addition to the following steps
2. When ceiling dome is to include and electrical fixture, measure the
fixture canopy cover. Drill a hole in the center of the ceiling dome, making
sure the hole is not larger than the fixture canopy cover
a) If hole is less than -1/2" in diameter, use a metal cutting twist drill bit
and cut from front of the ceiling dome
b) For holes -1/2" to 2” in diameter, use a fine blade saw and cut from the
front of the ceiling dome
c) For holes more than 2” in diameter, use a jig or sager saw with a fine
cutting blade and cut hole from back of the ceiling dome to prevent chipping
3. Center and install support member to ceiling joists directly over dome
for electrical junction box [A & B]. Feed wire through hole in ceiling dome
before installing ceiling wallboard
4. Make sure ceiling dome DOES NOT support the weight of the lighting or
ceiling fan fixture
5. Follow appropriate finishing instructions above
6. Re-connect fixture or ceiling fan. Slide fixture canopy cover up to dome
and tighten ring snug against dome. NOTE: You may need to purchase a longer
thread pipe or down rod to anchor fixture or fan, as supplied pipe or rod
may not accommodate dome thickness
