Rugged reliability, low cost of ownership and accolades from reviewers are just a few of the reasons why Grandio Greenhouses is winning over the world's toughest users. Made to meet the highest standards of amateur and professional gardeners, the 1.6mm profile aluminum frame provides a stronger and more durable build than its competitors. And the heavy-duty construction coupled with 10mm twin-wall polycarbonate panels provide and a perfect thickness for winter insulation. A wide range of features and accessories culminates in a well ventilated growing space and gliding double sliding doors resulting in an amazing gardening and greenhouse experience. The doors are hung from above which eliminates jamming and the door wheels are made from nylon for durability. The door wheel bolt is turned from solid brass with a smooth shank to reduce wear on the wheels.
