I was contemplating a project involving a large one-way/two-way mirror, like 3-4’ by 5’. It might work a little smaller, like 3’ by 4’. My understanding is that I’d want 3/16” or 1/4” thick for something that size to not have optical distortion issues.
I found two U.S. sources: TAP Plastics and twowaymirrors.com. TAP doesn’t have anything that large. At the other place, it’s … spendy. $1800 USD for a piece that big. For the smaller size, it’s “only” $720.
I’m not sure what the manufacturing challenges are at that scale but, based on experience with smaller sheets of coated acrylic, that seems awfully steep.
TAP’s maximum size seems to top out at 3’ by 3’ for ~$330. I could maybe do this with two panels but, it would be better without a seam.
Anyone know of more economical sources? Or why it should be that expensive at that size?
The thickest I see through Amazon is .12 inches and the largest sheet is only 24 by 36. I was pleased with the thin stuff I used for this project. SupremeTech might have bigger stuff directly.
