I have a collection of fairly lightweight acoustic panels that I want to suspend from a plaster ceiling (see mockup images below). My question: What is the best way to attach them?
Here’s the shape of the problem:
- 10 large panels @ 1.75 kg / 3.84 lbs each, 21 in wide at the narrowest
- 18 small panels @ 0.62 kg / 1.37 lbs each, 10.5 in wide at the narrowest
- Panels should be suspended ~2 in below the ceiling, so adhesives are not an option.
- The precise arrangement and small size of the panels means I can’t make them all hit joists.
- I expect I’ll want to suspend each panel at three separate points so I can level it. My thought is to use neodymium magnets at the end of long bolts/screws to allow fine position adjustments. That means that:
- I’m drilling 3*(10+18) = 84 holes in the ceiling here.
- Each individual hole carries a weight of no more than 0.6 kg / 1.3 lbs.
It’s an old house, so the ceiling is lath & plaster, not drywall. Things I’m wondering:
- Given the low weight here, are toggle bolts really necessary? Or can I get away with screws of some kind, hoping that most of the screws at least hit some lath?
- Alternatively, is there some kind of tiltable swivel mount I could use to level them, and thus need to position only one in the center of each hexagon instead of three at the edges?
- Other suggestions to keep this project manageable?
