Treated Wood Greenhouse Frame
I'm planning to build a 12x12 greenhouse with an 8 on 12 roof pitch using treated lumber (4x4 posts and beams, 2x6 plates, purloins, and ridge beam--double 2x6, and 2x4 studs, rafters, and mullions) and twin- or triple-wall polycarbonate glazing. Do I have to make special provisons to accomodate possible warping of the frame? Do I have to use special (beyond the recommended standard) techniques or materials to fasten and seal the PC panels? If anyone has experience building a PC on treated lumber greenhouse, I would be very grateful for the benefit of your experience. My email address is .
Thanks in advance,
