23.75 In. x 47.75 In. Prismatic Clear Polystyrene - 1A25001A at The Home Depot

Will it work for what exactly? Providing a textured pattern to a built in fluorescent ceiling light fixture? Yes.
Using it to build up helmets or armor? No.

If you're looking for sources for plain sheet styrene, try companies like Plastruct or Evergreen. Not sure what size sheets you can buy from them though.

I go this route. It's cheap, even with shipping and works well. No issues with glues or paints not sticking and the thickness I've been using can be cut with scissors easily
