Palram - Canopia Americana Greenhouse

The greenhouse includes a galvanized steel base for added support, but it must be anchored to a solid, level surface. We recommend installing it on a concrete slab, a heavy-duty timber frame, or a leveled gravel base to ensure long-term stability.

The barn-style design is specifically engineered for extra space, offering a peak height of 103.5 inches, or approximately 8.6 feet of usable interior height. This provides plenty of room for taller plants and comfortable movement while working inside.

The structure is rated for a wind load of up to 60 mph when properly secured with the included anchoring kit and a snow load capacity of 15 lbs per square foot. If you live in an area with heavy snowfall, we recommend clearing the roof periodically to prevent accumulation beyond the weight limit.

The side panels are designed to be virtually unbreakable and clear for maximum light transmission, while the 4mm twin-wall roof panels are slightly diffused to block harmful UV rays. This combination ensures your plants get the light they need while protecting them from harsh sun exposure.

The greenhouse features two adjustable roof vents that allow for natural heat dissipation and airflow. For better climate control during peak summer months, you may also want to keep the double doors open to encourage cross-ventilation.

While the greenhouse is designed for DIY assembly, it is a large project that requires at least two people due to the size and weight of the panels and frame components. Expect the process to take a full weekend, and be sure to follow the included manual closely for the best results.
