I used to have a greenhouse up north and got tired of constantly replacing broken glass. I used acryllic in place of the glass and never had any more problems. You can cut the acryllic with a regular circular saw if you cannot find it in exact size. I used to buy it from Mcmaster Carr catalog as they stocked it in 24 x24 inch size but I'm sure if you do a web search you can find it. I tried other plastics but found that acryllic did not cloud up over time.
