Cold frame construction question

Asked October 22, 2018, 5:09 PM EDT

I replaced my windows and would like to use one of the dual casement windows I saved to build a cold frame. I want to put the cold frame on my second story deck. I am concerned about cold air underneath the deck impacting the health of the plants. Would it be safe to grow vegetables in a box constructed of 2" thick pink polystyrene insulating panels?
