A:  At suntuf webpage there is an installation manual. I looked up your question. Cross supports (purlins) must be no more than 36" apart for Suntuf. This is the maximum recommended spacing. For most typical installations however 24” is recommended to give the best balance of economy, light transmission and structural support. The drawing in the manual shows the first purlin at the end of the panel nearest the peak. I used 24" purlin spacing for my roof panels, and I put a purlin at the end of the panel at the peak of the roof. We get a lot of snow and moderate wind, and I want the roof panels to be fairly rigid while maintaining maximum light transmission through the panels to the greenhouse. Snow drift from the roof to the ground can be 30" deep in a normal winter. That's why I put in a 30" above grade cinder block stem wall around the greenhouse. I don't think these panels are strong enough to be stressed by drift from ice and snow at the base of the greenhouse walls. Besides, I like the look of a stemwall covered by quarter sawn D-logs. That makes the greenhouse match the siding on the other structures in our compound at the top of the mountain.
