Any suggestions on materials that are light weight, durable, and sustainable? Specifically, I’m looking for something that has the durability of plexiglass for partitions for outdoor use (think retrofits for pandemic uses), but something that is more sustainable. Glass for all its pros and cons is too heavy and expensive, plus the framing elements alone would be expensive too. Other materials such as tack board or OSB coated with a sealer have been considered as well, but as you can imagine, cannot withstand rain or cleaning like plexiglass can.
Any thoughts welcome!
