Strength of plexiglass. 1/16 plexiglass as wall on 2x4 framing spaced 2ft on center. Is the plexiglass thick enough? Answered

Nothing will be anchored to just the plexiglass, nor will anything be leaned against it. Also framing is on & anchored to concrete floor & walls. There is very little to no give in framing.

What do you want it for a green house see through wall wind break?

Sheet plastic will do but you may need to predrill all the holes and take care screwing depending on the grade of plexiglass.

It will not meet fire or building code as a room divider in most places but then again most of the building materials we used 50 years ago won't ether.

Thanks everyone for the great feed back. I understand everyone's concerns about it being flammable. This room is going to be located in the building of a private business away from open flames & kids who might think its fun to melt it. But thank you for bringing this up as in the summer months it doesn't get quite warm in the building, so I will have to do some research on what temps it can withstand. Burf thanks for the concern about pre-drilling, I already planned on this & with new drills & drill attachments switching from drilling to driving is a snap quite literally. Also I plan to use a rubber or plastic washer to prevent over tightening. I probably should have explained the function of the room. I am making this room to enclose a bunch of shelving units that hold various things. All of the items on the shelves don't get used often so they collect dust & dirt & need to be hand cleaned whenever they need to be used. There is a lot of everyday foot traffic near these shelves. Your probably asking "why not just Sheetrock it?" Well then I would have to run electrical, my panel is very far away, I would have to run a couple hundred feet of wire just for a couple of lights. Also I feel as though plexiglass would be easier to clean than painted Sheetrock. I am leaning more towards 1/8 & a different material clear material for the roof. If anyone has suggestions on different clear materials send them my way. Thanks

The straight up answer is no, not for any practical purpose. Its not strong enough, its flammable, it emits toxic/noxious fumes when it burns, it is not durable enough and I'm certain it would never be approved for such usage by any code authority.
Installation would be a bear, every single attachment hole for nails or screws would have to be predrilled and over tightening any one would cause a crack or break.

Keep in mind that Plexiglas is flammable.
We just had this really stupid thing happen last November. One of the elementary schools was having a problem with a lot of broken windows. After many many replacements the school maintenance people got the idea to put a sheet of plexiglass on top of the window glass to reinforce it. It worked great until some kid got the idea to melt the Plexiglas with a lighter. It lit on fire and then set the wooden window frame on fire. The building itself is brick so the fire didn't bother the walls but it did spread through the window frame into the inside of the building. Most of the damage done was by the fire department who flooded several rooms.

So, be aware, it does burn.

They should have used polycarbonate - doesn't support combustion. There's a great video out there of two vandals. One throws a stone hard at a polycarb window, it bounces off and hits his friend, knocking him out. He picks up another stone, throws THAT, and knocks HIMself out....

It is expensive. It will still flex but should hold up built as you describe. It scratches easily and is a devil to keep clean. (Static attracts dust, wiping scratches it. You will be able to see the frame through it??

The plexiglass will be the exterior wall of the room (this is still inside a larger room so nothing is exposed to elements. There will be no interior walls ( exposed 2x4 ). I was planning on 4'x8' sheets. I'm trying to keep the building costs down. I need 12 sheets of 4'x8' and 1/8 will cost around $900 as where 1/16 would cost me around $500. Maybe a cheaper material for the roof, Home Depot has that wavy plastic material.

So you want to use plexiglass instead drywall? How large of a sheet will you want to use?

1/16 is generally best for glass replacements in picture frames. Because it's so thin it will break easily in a large sheet. You'll probably need to use 1/8 to 1/4 inch sheets.
