I have used plexiglas to make storm windows and it works well and fairly cheap.I'am about to build a cold weather camper for skiing and other things expedition style.(Built one before) Got some windows from a place in Summerland BC They custom build them. Think the average camper windows add up to about $1200 cdn with out shipping.
Their website is http://www.sunviewindustries.ca/ I know there are some stateside as well.
