The reason I started this ball rolling here is that I am not at all convinced that isolated panels do benefit from airgaps. More precisely, I think there is a gradual failure as area is decreased. Ethan sent me some Lab tests years ago. Like bobgolds.com, the 1:1 gap greatly helped LF. But again, the ANSI sampling is 10 sq contiguous yards afaik? I will look thro Erics Baffles again. Andre did you sot simething specific in that? Ta all
I removed the pic, I load it up here.
