A span greenhouse is an economical type of greenhouse, favored for its attractive arched design and low cost. The arched roof is aesthetically pleasing and provides a smooth line of sight. The structure requires minimal steel, offering excellent thermal insulation. With relatively low manufacturing costs, it is suitable for most regions in our country. Northern regions often use double-membrane greenhouses, while southern regions prefer single-membrane ones. It can achieve maximum light exposure within the visible range of 0.4-0.7 micrometers. After inflation, the layers form thick air bags, effectively preventing heat loss and blocking cold air intrusion. The use of double-inflated membranes significantly enhances the greenhouse's thermal insulation, reducing operational costs. The covering material at the top is a long-life polyethylene anti-drip film, with an outer layer that blocks ultraviolet rays and an inner layer that prevents condensation. The sides can be covered with either polyethylene anti-drip films or polycarbonate hollow boards, as per the customer's requirements.

Spanned Film GreenhouseFeatures:
