Arched ceilings do not have to incorporated into a home's infrastructure. Some manufacturers make an array of three-dimensional suspension systems in different shapes, textures and lighting options that can be added to existing homes. A free-hanging arched ceiling system requires plumb wires to support the weight of the structure. Installing one of the suspension systems should be done with care---without the proper preparation and technique, the installation could cause permanent damage to the original structure.
Instructions
1. Check the package upon arrival for any damages that may have occurred during shipment. Also, verify if all the listed parts are included. Do not attempt the installation if parts are missing or damaged. It may seem obvious, but don't skip the important first step: Read the instructional manual for an overview of the installation process. Improper installation can cause permanent damage to the arched-ceiling unit and its corresponding parts.
2. Refer often to the diagram that came with the arched-ceiling assembly. Allow for clearances of at least 23-1/4 inches from walls and structural beams.
Locate the flush main tee, a curved structural support beam, to lay out the first row of main tees. Note the two different ends on the main tees, which include flush-cut and splice ends.
3. Select a starting point relative to the installation site, such as a wall or column. Use the installation guide to lay out the on the ground relative to their intended placement. Place a flush-cut main tee at the starting or ending points in the first row.
4. Use a permanent marker to mark the pre-punched hanger holes spaced about 2-feet apart. Use ceiling hooks to carefully mount the hanger wires within the corresponding marks on the main tees. The hanger wires will have varied space between them because of the curvature in the main tees.
5. Attach the flush-end main tee on the hanger, based on the elevation specified in the diagram. Punch or drill additional hanger holes to work around obstructions in the existing ceiling. Ensure that the space between two hanger wires does not exceed 4 feet.
Some installations will require you to make a flush-end main tee by cutting a splice-end main tee. Find the cross-tee slot on the flush-end main tee and insert the cross-tee into that location, then mark it. Use a ruler to draw a straight line at the mark. Use tin snips to carefully cut along the marking.
6. Use a splice-end main tee and insert the splice tabs into the ends of the adjoining main tees, then partially bend the tabs to secure the main tees into place. Make upward and downward alignment adjustments to prevent future problems with the rest of the assembly. Ensure the straightness of the wire before proceeding.
Attach temporary support braces to the wall to ensure stability of the the first row's main tee.
7. Observe the alignment of the first hanger wire rows and use it as a reference when installing the second set of hanger wires. Use a level, string lines or laser pen to ensure there is a 2-foot gap between rows. Hang a consecutive flush-end main tee and connect it to the first row through a cross tee. Continue hanging the main tees along with the cross tees until you create a grid. Inconspicuously tighten the ends of the hanger wires to prevent visibility after final installation.
8. Lay the 2-foot-by-2-foot panels into the newly constructed grid according to the directional markings on each panel. Slightly bend the hold-down tabs on each panel, and close any gaps. Be careful, as overextending the hold-down tabs could cause permanent damage to the panel.
9. Remove the temporary support bracing from the walls, columns, or ceiling.
10. Follow the diagram to install each edge trim part . Slide each edge trim part into the grid; the edge trim parts measure 1/2-inch shorter than the main tees.
Install the fascla splices by squeezing and hooking the bottom tab over the edge of the trim, then bend it over the top of the splice. Hook each corner clip over the edge of the trim, then bend the tabs over the top to snap into place.
Ensure proper trim fitting against the grid, then screw two 6-inch-by-3/8-inch self-tapping screws into each edge trim part.
