This beautiful barn-style greenhouse gives you a year-round growing space with a heavy-duty aluminum frame and 10mm twin-wall polycarbonate panels.
Engineered to perform in harsh environments, the Grandio Summit's rugged durability makes it one of the most insulated greenhouses on the market. Its barn shape design is both elegant and functional, allowing plenty of growing space while looking great in your yard.
Made to meet the highest standards of hobby and professional gardeners alike, the 1.6mm profile aluminum frame provides a stronger and more durable build than its competitors.
The Summit’s range of features and accessories provides a well ventilated growing space with ample roof windows and re-engineered sliding double doors. The UV-protected 10mm paneling has an (R) value of 1.89* and heat loss (U) value of 0.53, allowing for optimal insulation in all climates.
The doors are hung from above which eliminates jamming and the door wheels are made from high-quality nylon for durability. The door wheel bolt is turned from solid brass with a smooth shank to reduce wear. The doors come standard with heavy-duty lockable door handles and included key.
Carefully engineered to the highest standards, gardeners of all types will love the combination of strength, quality, performance, and value that Grandio Greenhouses are known for.
