Know before you buy
Yes, it is engineered for year-round use with a 1.6mm thick aluminum frame and 10mm twin-wall polycarbonate panels. It is rated to handle wind speeds up to 76 mph and a snow load capacity of 25 lb/ft², making it suitable for most climates.
The kit includes a foundation base, which provides the necessary structural support and squareness for the frame. While it can be placed on various level surfaces, we recommend anchoring it securely to your chosen base, such as concrete or treated timber, for maximum stability.
The greenhouse features three manual roof vents that allow you to regulate airflow and humidity levels effectively. By adjusting these vents, you can prevent overheating during warmer months and maintain the ideal climate for your plants.
Beyond its classic look, the barn-style roof is functional; it provides increased vertical clearance, which is ideal for taller plants like tomatoes or small trees. This design also helps shed snow and rain more efficiently than a standard flat-pitched roof.
The double sliding doors offer a 44-inch wide opening, which is generally sufficient for standard garden carts, wheelbarrows, and most potting equipment. The doors are designed to be bind-resistant for smooth operation.
The 10mm thickness provides superior insulation compared to thinner panels, offering an R-value of 1.89. This helps maintain a more stable internal temperature, which is critical for extending your growing season into the colder months.
