The XL Grand Gardener 8x16 Clear features two kinds of virtually unbreakable polycarbonate panels to give you the best of both worlds. Crystal-clear polycarbonate side walls allow clear views while being ultra-safe and provide over 90% light transmission and the twin-wall roof panels diffuse over 70% of sunlight for a soft, even light. The heavy duty, UV protected extruded resin frame with its additional aluminium roof profiles improves both insulation and durability.
