What are the advantages of multi-span greenhouses

1. The heat loss in energy-saving glass greenhouses mainly occurs through the following channels: heat dissipation through the glass enclosure structure, which can account for 70% to 80% of the total heat loss; radiation to the sky; ventilation; air infiltration and heat dissipation; and underground heat transfer. Energy conservation in greenhouses involves reducing heat loss. An effective method is to install thermal insulation curtains, which can reduce heat loss at night. Under the premise of the lighting requirements for crops, it is better to install double-layer transparent materials, which can reduce heat loss by 50%. The use of cold-proof trenches and filled insulation materials can also effectively reduce heat transfer on the ground.
II. Advantages
1. Large illumination area with uniform illumination.
2. The glass greenhouse has a long service life and high strength.
3. It exhibits strong corrosion resistance and flame retardancy.
