Prices are the lowest current price in each series, in Canadian dollars, before tax and before any shipping charge. They change without notice. The price on the product page is the one that applies.

Sizes listed are the sizes we can ship today. A series may be manufactured in more sizes than we stock. If you need a size that is not listed, call us at 1-877-322-5487 and we will tell you what is possible.

Heights are external, measured from the base rail. Peak height is at the ridge, eave height is at the side wall where the roof begins. Both are converted from the manufacturer's published metric dimensions, so a fraction of an inch either way is rounding, not a difference in the product.

Floor area is the internal floor of the greenhouse, measured from the manufacturer's published base dimensions. It is the whole floor, so it includes the doorway and the path you walk down. Usable planting area is smaller, commonly a third less once you leave room to walk. Ranges cover the smallest to the largest size we stock in that series. The hexagonal Oasis models and the T-shaped Victory and Triomphe use Palram-Canopia’s own published floor area rather than length times width, because their plans are not rectangles.

Glazing figures describe the panel type, not a thermal rating. Twin-wall polycarbonate holds heat better than clear single-wall and diffuses light. Clear single-wall gives you a see-through view and more direct light. Thicker twin-wall holds more heat again.

Snow and wind ratings are the manufacturer's tested figures for a correctly assembled and correctly anchored greenhouse. They are not a guarantee for your site. Clear snow from the roof, and check your local building requirements before you build.

Base means what comes in the box. Our aluminum models include a galvanized steel perimeter rail. The Rion resin models use a separate resin base kit. None of them include the foundation, which you build yourself from concrete, pressure-treated timber, a deck or paver blocks.

Extendable describes the design. Extension kits are sold separately and are not always in stock. Check with us before you plan around one.

Not published means the manufacturer does not state that figure for that model. We would rather leave it blank than print a guess. Ask us and we will check the assembly manual for you.
