Americana 12 ft. x 12 ft. Greenhouse Kit - Silver Structure & Clear Panels

Structure color

The Palram – Canopia Americana 12x12 Greenhouse offers a large gardening space in a classic barn shape with hybrid glazing.

Measuring 12 Ft x 12 Ft, the Americana is large enough to create the garden oasis you’ve always wanted. The barn-style roof means there is ample room to stand, and the footprint gives you plenty of space to move around and plant a garden worthy of your dreams.

The Americana is designed with two types of panel glazing: twin-wall roof panels and crystal-clear side panels. This combination provides a precise balance for your plants, protecting them from direct overhead sunlight and retaining heat while allowing 90% light transmission to nourish your garden with adequate morning and evening light exposure. Both panel types are made of polycarbonate, an ideal material for greenhouses due to its strength, safety, and look.

The Americana features a reinforced, rust-resistant aluminum frame, galvanized steel base, and low threshold or easy wheelbarrow access. With double, swinging doors and two vent windows, you'll have an abundance of airflow and control over the temperature and moisture levels to create a comfortable environment for you and your plants.

With the Americana, you have room to grow and room to share your love of gardening.
