  • Superior Quality

    Made to meet the imposing 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 or 6mm twin-wall polycarbonate panels is a perfect thickness for winter insulation.
