Engineered to perform in harshest environments with standard high-strength frame and additional roof truss and snow load supports. The Grandio Elite's rugged durability, makes it the most insulated of the greenhouses on the market and it's barn shape design with an 8' tall roof peak makes it both elegant and functional, and allows plenty of growing space.


Sunglo Greenhouses

All Sunglo Greenhouses are constructed of a durable aluminum framework with impact resistant acrylic panels. Before Sunglo built their first greenhouse they knew they were going to be strong but didn't know how strong! After running some tests we found our Model 1000C supported over 2,500 pounds of snow and withstood wind gusts of up to 80 miles per hour without worry. The heavy gauge DR Plexiglas also has 100 times the impact strength of any single pane glass greenhouse today.

Juliana Premium Greenhouse

The Juliana Premium greenhouse is a beautiful addition to your yard and garden. The thickness of the polycarbonate makes the Premium ideal for wintering over your plants, while providing a welcome escape from the cold winter months. Some people even set up a small table and chairs - a place to relax and enjoy a warm respite from the cold. The nearly eight-foot peak and four and three-quarter-foot sidewalls makes working in the Premium comfortable and spacious. The floor-plan allows considerable space for seed starting, container plantings, tropical plants and trees, orchids and more! The Juliana Premium series is truly a premium greenhouse line with many outstanding features. It is distinguished by thick 10mm polycarbonate and extra-strength profiles. The unbreakable polycarbonate panels offer superior insulation, and fit snuggly into the greenhouse with a tight gasket system, which also gives a nice finished look.
