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. Proudly manufactured in the USA, Sunglo Greenhouses offer an unsurpassed combination of durability, longevity, transparency and value!
