The kit includes labeled parts, stainless hardware, basic tools, and step-by-step instructions. The larger panels on the 6x12 are easier with a helper.Do I need a foundation?The included flat-mount anchor kit works on a level concrete slab or wood deck. For installation on soil or grass, the steel base kit (Dirt anchor option) is required. It creates a strong perimeter frame and anchors to the ground with earth anchors set in concrete.Can it be used year-round?Yes. The 10mm twin-wall panels hold heat in cooler months while passing plenty of light. Many owners add a small heater for winter frost protection and shade cloth for peak summer.How does it handle wind and snow?The Element is rated for 76 mph winds and 25 lbs per sq ft of snow when properly anchored. In exposed or snowy sites, add the steel base kit and the Element snow load kit for extra security.
