I have seven 24 x 13.302 glass panels that I want to use to build a greenhouse. I also have a lot of 2x4x14s and 2x4x8s that I can use. I would like for the greenhouse to be as close to 14x14 as I can get.
Can I span 14'. with just 2x4x14s for ceiling joists to support the window panels with no supporting beams underneath?
