Single Span Greenhouse with Double Wall Design

Single Span Greenhouse with Double Wall Design An inner protective layer is added to each greenhouse, forming a double-layered insulation structure. It adopts a nested "outer greenhouse + inner greenhouse" structure. The outer greenhouse uses anti-aging PO or PEP film to ensure light transmission and weather resistance; the inner greenhouse uses a thin insulating film or insect-proof netting to form a sealed double-layered space, constructing a natural insulation barrier. The greenhouse span is typically 4-6 meters, and the height is 2.2-2.8 meters, with ventilation openings and operating passages provided, balancing insulation and ease of management. Its core function is to enhance temperature and humidity retention, reducing heat loss.   In winter, the temperature inside the green house can be 5-8℃ higher than a typical single-span greenhouse, and in summer, the double-layered structure blocks direct sunlight, reducing high-temperature stress. It is suitable for high-altitude, high-…
