I built mine of double-pane sliding glass doors.  There is a  
manufacturer of them here, and they have to replace any that "leak".   
I bought up the "leakers" really cheaply over a couple of years.

Another cheap, though time-consuming idea:

In the Czech Republic I saw many pickle jar greenhouses.  People  
collected big restaurant-sized pickle jars and made them into small  
greenhouses (maybe 3 metres by 4).  They would be well-insulated.  I  
never saw one up-close, so I don't know how they glued them together.
