I'm wondering if anyone knows of a source for opaque plastic sheet 1/8" - 1/4" thick that won't mind being in close proximity to heat as I don't want it bowing over time.
What I'm looking for is something to make an opaque light blocker as pet stores use to hide the works of their displays. I looked up pet shop displays but they don't sell just their parts for DIYers of course . And all I could find for "Opaque plastic sheet" on google was distributors in China and Thailand who want to sell a boat load. And I only need a dozen or so 48" x 12" pieces to last me a lifetime of building.
Here's an example of what I am talking about:
The sliding plastic panels you see on top of each row of tanks, hiding the lights and tank access. I can use 1/4" wood of course but I'd really like to have some of that light blocking plastic.
Thanks for any leads you may be able to toss my way!
