How do I install a ceiling-mount projector in a room treated with the Iso-Wall system on the ceiling?
If your projector is less than 30 lbs. in weight then the resilient channels will have no problem supporting it. However, you will need to use something besides drywall in order to get sufficient grip for the mounting brackets. We recommend using 1/2″ thick high-grade plywood (such as a marine-grade plywood) as your first layer, in place of the moisture resistant drywall, at the location where your projector will be placed. Make sure you use a large enough section of plywood so that it is supported by at least 3 of the resilient channels. You may also want to use additional screws to secure the plywood to the channels. When attaching your projector’s mounting brackets, it is a good idea to use toggle bolts (Molly bolts) for added weight support. Be sure to screw ONLY into the plywood and/or resilient channels and NOT into the joists above.
