What the manual says that the product page doesn't
NO wind rating anywhere in the manual. Checked the full extracted text for mph, km/h, psf and kg/m — zero numeric ratings of any kind. The manual only advises siting somewhere 'sheltered from wind' and orienting the door away from prevailing winds.
source documentNo rating exists to be conditional. Instead the manual disclaims responsibility: 'conditions vary from site to site, and affect practicality and effectiveness of anchoring methods substantially... You are responsible to ensure the greenhouse is [anchored]' and it excludes liability for 'damage... that occurs as a result of improper greenhouse anchoring'.
source documentNO snow load published. The manual carries a SNOW/DEBRIS ACCUMULATION HAZARD warning instead: 'The heavy weight of accumulated snow or other debris can cause parts of this greenhouse to buckle suddenly.' A hazard warning is not a rating.

Where to buy
Advertised prices, checked daily. Shipping is extra unless the retailer states otherwise — on a greenhouse, freight can change which seller is actually cheapest. We do not yet track a retailer for this model.

Climate notes
Our analysis of the published figures — not a manufacturer claim.
- Cold climates
- No snow load is published — only a warning that accumulated snow can cause the structure to buckle suddenly. Treat as unrated for snow.
- Exposed and windy sites
- No wind rating is published and the manual explicitly disclaims liability for anchoring failure, putting the whole judgement on the buyer. For an exposed site there is nothing here to compare against and no manufacturer figure to rely on.
What we don't know
35 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.
