A multi-span greenhouse is an economical option, favored for its aesthetically pleasing curved design and low cost. The arched roof is both beautiful and functional, offering a clear line of sight. The structure requires less steel, ensuring good insulation properties. With relatively low manufacturing costs, it belongs to the economy-type greenhouse, suitable for most areas in our country. In northern regions, double-layered film greenhouses are more common, while single-layer film greenhouses are often chosen in southern areas. It can receive maximum light within the visible spectrum of 0.4-0.7 micrometers. After the layer film is inflated, it forms a thick air cushion, effectively preventing heat loss and blocking cold air intrusion. Using double-layer inflated film can significantly improve the greenhouse's insulation performance and save operation costs. The roof is covered with polyethylene anti-drip longevity film, with UV protection on the outer layer and anti-dew on the inner layer. The sides can be covered with either polyethylene anti-drip longevity film or polycarbonate hollow panels according to the user's needs.

Twin-span film greenhouseFeatures:

1. Compared to traditional greenhouses, the interconnected greenhouse structures and greenhouses offer a significant advantage in utilization space over the traditional ones, boasting a much larger area of use.

2. More uniform than traditional greenhouses, with scientific operation, time-saving, and efficiency enhancement.

3. Film greenhouses are cost-effective, suitable for large-scale promotion in our country.
