The multi-span greenhouse is an economical greenhouse, which is very popular with users for its beautiful arc shape and low cost. The arc-shaped roof is beautiful and the sight is smooth. The structure uses a small amount of steel and has good thermal insulation performance. The manufacturing cost is relatively low, and it is an economical greenhouse suitable for most areas. Double-layer film greenhouses are mostly used in the north, and single-film greenhouses are mostly used in the south. It can get the maximum light within the range of 0.4-0.7 microns of visible light. After the film is inflated, a thick air bag can be formed, which can effectively prevent heat loss and prevent the invasion of cold air. The use of double-layer inflatable film can greatly improve the thermal insulation performance of the greenhouse and save operating costs.
