What kind of acrylic is usually used in tarantula enclosures?

That's why I was confused by the person's statement. I don't know enough about acrylic materials. I thought for sure if a thicker material bowed, how come I haven't heard of this w/ all the "new" fish tanks that are made of acrylic that is even thicker, and as you said, have more force against it with water inside.....

This is just what Ive noticed. I suspected it was due to it being cut smaller and going through heat/cold every single day. It makes the lids warp ridiculousely and would be more then happy to pull out old tanks ive made and take pics of them to show as proof - I have no reason to make this up

I find this quite interesting. Unless there are big inherent stresses in the material, i don't know that slight hot/cold variation alone would do this.

Besides the tank example I used earlier, I have used several acrylic vent hoods with incandescent bulbs. The only time I've ever seen waviness is from prolonged high heat near where the plastic becomes flexible. I think it's called glass transition temp (correct me if I'm wrong).

A florescent bulb operates around 112F (44C) where the glass transition temp is 185F (85C).

I had a guy leave the incandescent bulb on overnight on a piece of 1/4" acrylic. It's now a nice little hump.

Now if it was glued to something with stress in the material (even steel has to relax after being cut) then heat/cool might influence it.

Don't know I have used 1/4 forever and it fits perfect in the lip and haven't had an issue

Once you cut .22 or 1/4 down to the right sizes it gets really ridged and does not want to bend..these are some I just finished for five gallons I have never had an issue with this size warping Cept on high heat reptile tanks and anything would warp at 100 degrees lol

Appreciate the info on that size!

For the record most companies that advertise 1/4 actually are like .22 or .23 kinda like how 2/4's aren't really 2 inches by 4 inches. I cut all these on a table saw with a finer blade and drilled with a regular drill bit I got a few chips on the holes but I was going fast it was getting dark and 30 holes on the drill press was getting old haha
