Our Cold Box is complete! This will be where we store our fresh produce after we harvest it in the field, before we take it to the farmers markets, CSA dropoff or deliver to local restaurants. We constructed this cold box out of 4" insulation panels, encapsulated in aluminum sheeting. I bought them as a set of various lengths, and had to figure out how I wanted to build the box to utilize the panels and make a nice sized box. After setting up a base using 4x6 and 6x6 wood, we added some additional 2x6 boards and then topped with plywood as a floor. We then attached corners to the base to hold the panels in place. The panels snapped together and are very rigid. Putting the panels on the roof helped hold everything together. We then put panels on the plywood inside the cold box to add additional strength to the floor and added insulation. We are anticipating that we will not need to add any form of AC unit, we built this box on the north side of our barn, and it will get very little sunshine and it stays very chilly inside! After all is said and done, it is roughly 13'W x12'L x9'H.
