I found some 6 mm double wall polycarbonate on sale for $1.10/ft2 that I'm planning to use for my gh roof. It has a 10 year warranty and is UV stabilized. Also 82% light transmission. Are there other features/specs I should be looking for? Thanks.

That sounds like a pretty good price, based on a very cursory web search!


Possible things to consider that you haven't mentioned:

How much insulation does it provide? (R-value)

Do you want transparent, or something that will provide diffuse light?

How strong is it, to resist snow load, goats climbing it, etc?
