Glass greenhouses are the cornerstone of modern commercial horticulture, adopted globally for their eco-friendly design, natural growing environments, and science-driven planting. Pioneered by the Netherlands, a leader in protected agriculture, this technology has spread worldwide。 Technological iteration has diversified greenhouse structures, including Venlo-type multi-span (large-scale commercial standard), corrugated-roof (cost-effective medium projects), arched (small-medium farms), circular (agritourism/exhibitions), and customized designs. Their functions also expand beyond crop production to seedling breeding, scientific research, exhibitions, picking gardens, agritourism, and greenhouse catering—each needing tailored glass solutions. Today, smart greenhouse frameworks are globally standardized, with Q235B hot-dip galvanized steel pipes as the dominant load-bearing material. Valued for corrosion resistance, structural stability, and ability to withstand extreme weather, it ensures facility longevity. With structural engineering standardized, design focus shifts to high-performance greenhouse glass, used in two key areas: side-wall cladding and rooftop covering, each with distinct specs. Side-Wall Glass: Thermal Insulation, Safety, and Uniform Light Distribution Side-wall glass maintains temperature, ensures safety, and optimizes light for edge-zone crops— which typically get less light than central crops, causing uneven growth. Designers prioritize light transmittance while preserving insulation and safety, using insulated laminated glass as the global commercial standard. The two most common specs are 5 mm clear tempered...
