I started at Charley's Greenhouse but my particular greenhouse was all custom. This is the link to the glazing used. Skip down to 16mm (5/8") Super 5X-Wall Storm

What's Charleys is showing now is nothing like mine. They used to have about 20 different designs and now seem to have 3.
My greenhouse is heated by a solar hot water system. Its not as efficent as I was led to believe as there's not a lot of heat and sun in the winter (but well worth it to see the smile on my techno-nerd husband's face). The only reason the solar system works well in winter is the the giant Polaris burner heating water at a pretty low price. The utility heater as a back up hasn't been needed too often.
