Double Arch Double Layer Film Greenhouse

The Double Arch Double Layer Film Greenhouse is a professional energy-saving agricultural greenhouse specially designed for cold climate regions and year-round off-season planting.Optimized based on traditional single-layer film greenhouses,it adopts an independent double-arch steel structure covered with double-layer agricultural plastic film.A sealed air insulation layer is formed between the inner and outer films,which greatly improves thermal insulation performance,structural stability and wind and snow resistance.Featuring low investment,outstanding frost resistance and flexible configuration,this greenhouse has become one of the most cost-effective planting facilities for seasonal vegetable cultivation,seedling breeding and cold-region agricultural production.

The greenhouse adopts a reinforced double-arch frame system with inner and outer double-layer arch pipes and stable auxiliary support structures.The entire frame is made of high-quality hot-dip galvanized Q235 steel pipes,which are anti-rust,anti-corrosion and weather-resistant for long-term outdoor service.Compared with ordinary single-arch greenhouses,the double-arch design effectively disperses wind and snow pressure,greatly improving overall structural strength.It can adapt to harsh weather such as strong winds,heavy snow and low-temperature frost,ensuring stable operation in high-latitude cold areas.The assembled structure allows fast on-site installation,simple maintenance and flexible dimension customization to fit different farmland scales.

The double-layer film covering system is the core highlight of this greenhouse.It uses high-transmittance,anti-aging and anti-fog agricultural polyethylene film.The outer film is UV-treated to resist long-term sunlight aging,wind erosion and rain corrosion,extending the service life of the covering material.The inner film adopts anti-drip and anti-fog coating to prevent condensed water accumulation and dripping,effectively reducing crop diseases caused by high humidity and ensuring a clean and healthy growing environment.The double-layer film structure maintains high light transmittance,providing sufficient and uniform sunlight for crop photosynthesis throughout all seasons.

This greenhouse achieves superior energy-saving and temperature-preserving effects through the internal air cushion layer formed between the two film layers.The closed air layer greatly slows down indoor heat loss in winter,increases internal temperature by 4–8 degrees Celsius compared with single-film greenhouses,and effectively prevents crop frost damage.In summer,the double-layer structure reduces heat conduction and avoids excessive indoor temperature surge,realizing natural and stable temperature regulation.This unique performance significantly reduces heating and cooling costs,making it highly suitable for year-round planting in areas with large temperature differences and cold winters.

The Double Arch Double Layer Film Greenhouse supports flexible matching of functional auxiliary systems to meet diversified planting needs.It can be equipped with external shading systems,top and side ventilation devices,fan and wet curtain cooling systems,rolling thermal insulation quilts,and automatic irrigation and fertilization equipment.In winter,the thermal insulation quilt further enhances night heat preservation;in summer,ventilation and shading systems effectively reduce high-temperature stress.The combination of multiple systems realizes precise control of indoor light,temperature and humidity,breaking seasonal restrictions and achieving continuous off-season production.

With reliable structure,prominent energy-saving performance and extremely low construction and maintenance costs,the Double Arch Double Layer Film Greenhouse is widely applied for vegetable planting,strawberry and fruit cultivation,flower growing,seedling nursery and medicinal crop planting.It offers a perfect low-cost and high-efficiency solution for cold-region agriculture and off-season commercial planting,remaining the most popular and practical film greenhouse for global small and medium-sized agricultural investors.
