Frost King Window Kits - Use Case #45
How about Frost King Window Kits as a passive solar collector? This Frost King user has been experimenting with living off the grid for the past few years, and he's recently started using Frost King Window Kits to construct a makeshift Greenhouse attached to the main trailer.
"I used Frost King plastic film to make a passive solar porch to heat my RV and grow winter vegetables. I also used Frost King window insulation kits to seal off my RV windows from the cold winter air."
In this case the Window Kits are used to keep the warm air inside the trailer's green house from escaping out into the cold winter. A quick and dirty fix to growing vegetables in the cold of winter. It's easy and cheap. Put it up in the winter, pull it down in the spring.
