They also would be sturdy enough to screw my ring magnets into and I'm guessing the neodymium magnets can hold the weight.
You're welcome. I must say that I didn't pay enough attention to the boards you first linked to, so I thought they were thicker. The reason why I suggested PVC/kapa line is because it's lighter. But, anyways, the boards you've mentioned are stronger and the magnets should hold them if you're sure those cross sections have good attraction to magnets. But, again, it seems to me that screwing the magnet rings is more work than needed, and you should avoid it unless you're absolutely sure the screw heads won't compromise a perfect contact between the magnets and the cross sections; just think how much less work it would be to just sit a drop of glue for each magnet.
As much as I love your idea and think it would look great, I only have 1/4" between my screen top and my ceiling. I made a point of maximizing my screen height and I literally only have 1/4" on top and bottom and at some spots only 1/8". The frame is level but not perfectly straight. I'm not sure my covered panels can fit in there without hitting the screen. My screen actually swings up to gain access to the shelving behind it so I can't even jam it in place without affecting the travel. I may be able to get away with putting the panels in place like hung ceiling and then using the magnet approach to cover the cross members.
I hadn't really considered the option of simply replacing the current panels for the ones covered in velvet; or instead of replacing them, just slide the new ones beneath them. For the cross sections, before thinking about using magnets, you could buy one of those rolls of black velvet tape and try to test with a sample how much residue they leave on the cross sections after removal. This velvet tape will probably not look as dark as triple velvet, but I wouldn't care about that.
Another option would be to do it your way but just but them up to the front of the screen but that would look hokey on the right side where the screen stops and there is a gap over to the right wall. (my next screen is going to fill that gap)
If you still want to consider some hanging-with-magnets options, here's 2 other materials that may work:
- 0,2 or 0,3 mm zinc sheets. Zinc holds very strongly to neodymium magnets, and although it isn't lightweight, with this thickness it's not going to be too much weight if you don't spare the magnets (and as long as those cross sections have good attraction to magnets too). This would save you the task of gluing the magnets, thus giving you a lot more freedom to try different placements.
- 0,3mm PVC sheets, with magnets glued to them. Very lightweight, but much more flexible than the zinc sheets. Choose one that's porous so that the glue will hold better.
Since these materials are flexible, here's a mounting suggestion:
These two options should be less expensive than what we've discussed so far.
Finally, there's this kind of very thin "rigid" PVC (I don't know the price):
Notice that you'll probably find these materials at lower prices if you buy them to dedicated vendors than to big stores like Home Depot.
Thanks for all the help! Keep the ideas coming please. Many heads are much better than one!
