ECONOMICAL – Our greenhouse kits feature a thermostatically controlled ventilation system and aluminum bench framework. Besides the fact that a Sunglo Greenhouse is a good buy, since it has such a long life, it is extremely economical to operate. Sunglo Greenhouses are constructed with two wall panels. This double wall construction allows for better temperature control than glass. The two layers of high-impact acrylic plexiglass create a 1 1/2 inch dead air space which provides 10 times the insulation of a single pane of glass! This makes a Sunglo Greenhouse energy efficient enough to use all year round no matter where you live!

STRONG – Designed 40 years ago by two experienced former Boeing engineers who

knew all about precision and strength. All Sunglo Greenhouse Kits are constructed of a durable aluminum framework with impact resistant acrylic panels. Before we built our first Sunglo Greenhouse we knew they were going to be strong but we 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. Our heavy gauge DR Plexiglas also has 100 times the impact strength of any single pane glass greenhouse today. In Seattle we have visited customers with original Sunglo greenhouses that are over 35 years old.

    With knee wall that requires a ‘door drop’ panel above the door.

    You can raise the greenhouse to any height using materials of your choice like wood or concrete. Simply order a “door drop” panel for above each door that matches with the height of the wall. A 2’ high wall would make the top of the door line up exactly with the top of the wall. Raised greenhouses give a nice spacious feel, allow warm air to rise away from plants, allow for hanging baskets and taller plants.




  • Doors
    Double French doors allow for easy access.
