Hello,
I would like to ask about using corrugated polycarbonate panels on a metal frame. I have an old metal shed (12' x 20') that I would like to change over to a greenhouse. The frame is made of 2.5" square metal tubing that is pretty stout, and the pieces are connected with self-tapping screws.
My concern is the effect that our summer heat will have on the panels. I am in zone 8 in Texas. If I use the recommended closure strips, will they keep the polycarbonate panels far enough away from the metal that they will not be damaged? I am pretty sure that fiberglass will hold up, but I have recently started looking at polycarbonate panels.
If possible, I would like to use white colored panels that will block about 40% (or perhaps a bit more) of the sun.
If it will work, would wooden or foam closure strips be the better choice? Also, is there a particular brand of polycarbonate panel that is better than others?
Thanks for any help.
