What the manual says that the product page doesn't
The manual makes a weather claim with no number behind it: the structure "has been designed to withstand extreme weather conditions such as high winds and accumulated snowfall." There is no wind speed, no snow load, and no test or code reference anywhere in the document to support it. Compare Riverstone, which puts 113 mph and a 1-second gust basis in writing on the Monticello, or Palram's Oasis, which carries a formal EN 1090 declaration. A phrase like "extreme weather conditions" cannot be checked against your local design wind speed, so it should not carry weight in a purchase decision.

What we don't know
44 of 46 fields are still unresearched, and fields marked not published mean the manufacturer does not state them — that is a finding about the product, not a gap in our research.
Every figure above links to the document it came from. We have not tested this greenhouse. Local wind, snow, permitting and foundation requirements vary; confirm anything that matters with the manufacturer and your local building authority before buying.
