Hello, I am new to this forum and am in the process of building a 12x12 greenhouse in south Texas.
My plan was originally to put a sloped roof on my greenhouse, but I came across a great deal ($24 each) on new 36x72 double pane, argon filled vinyl windows. These are the same windows I am using for the sides.
If I were to go with a pitched roof rather than a sloped roof, I think the windows would be much easier to install. If I go with a sloped roof, I would probably go with 26"x12' clear plastic roof panels that cost about $32 each.
One thing that I worry about with the plastic panels is heat loss. The worries I have with the windows are weight, glass breakage from storms and trapped heat. Either roof will have two 750 cfm solar roof vents. These vents will have a temp setting on them for automatic turn on and turn off.
I will have some good afternoon shade since we are looking at 100 plus degree weather in the summer months. Building will have East/West exposure on the sides with the most window area.
Plan to put in a water catchment system that will hold about 600 gallons of rain water as well.
Thoughts? Recommendations? Arguments for or against one design vs the other.
