/diy/ - Do It Yourself

Any of you guys have experience working with polycarbonate sheets?

Im thinking of turning upper half of my old billy shelf into a display cabinet.

It would involve mounting side door and replacing wooden shelves with transparent ones. I intend to use polycarbonate sheets, but i am unsure what thickness should i use

So, will 3mm polycarbonate sheet shelf be thick and rigind enough to hold its own weight and additional 2-4 kgs of stuff? If not, what thickness should i use?

Shelves dimensions are about 65x22cm.
