A multi-span greenhouse is an economical option, favored for its graceful arch design and low cost. The arched roof is aesthetically pleasing with a smooth line of sight. It features minimal steel usage and excellent insulation properties. The manufacturing cost is relatively low, making it an economical choice suitable for most regions in our country. Northern regions commonly use double-layer film greenhouses, while southern regions often opt for single-layer film greenhouses. It can achieve maximum light transmission within the visible spectrum of 0.4-0.7 micrometers. After the film is inflated, it forms a thick air cushion, effectively preventing heat loss and blocking cold air intrusion. The use of double-layer inflated film significantly enhances the greenhouse's insulation, reducing operational costs. The roof is covered with polyethylene anti-drip longevity film, with an outer layer that blocks UV rays and an inner layer that prevents condensation. The sides can be covered with polyethylene anti-drip longevity film or polycarbonate hollow panels as per customer requirements.
