What Is Greenhouse Tempered Glass?
Greenhouse tempered glass is a kind of high-performance safety glass designed for the greenhouse environment, combining the high strength and safety of tempered glass and the special needs of the greenhouse for light transmission, heat preservation and weather resistance. It can resist hail, strong winds and other bad weather, while providing uniform light and stable temperature and humidity environment for plant growth, is one of the core covering materials of modern efficient greenhouse.
| Core performance parameters | ||
| Parameter | Ideal value | The impact on crops |
| light transmittance | ≥91% (ultra-clear glass) | The efficiency of photosynthesis is increased by 15% to 30% |
| Diffusivity | 30% to 50% (frosted/micro-edge structure) | The light is evenly distributed to reduce leaf scorching |
| Ultraviolet ray transmittance | Adjustable (Coating control 0% to 80%) | Affecting anthocyanin synthesis (key to flower coloring) |
| Thermal coefficient (U value) | ≤2.8 W/(m²·K) (single layer) | Core indicators for winter heat preservation and energy conservation |
Key process technology
Greenhouse tempered glass substrate
The iron content is ≤0.015% (0.1% for ordinary glass), reducing the absorption of green light and increasing the light transmittance to 91.5%
Anti-reflective coating (AR layer
Double-sided coating increases light transmission by 3% to 5%, and the annual production increase benefit is greater than the coating cost
Intelligent dimming coating
Electrochromic film layer (with adjustable light transmittance of 50% to 90%), to prevent strong light stress in summer
Self-cleaning nano-coating
TiO₂ photocatalytically decomposes algae/dust, reducing light transmittance by 70%
