Light-Enhancing Agricultural Greenhouse Glass
we manufactures greenhouse glass with tunable haze and high direct transmittance — engineered to match every latitude, climate, light condition, and crop. Transmittance (direct and hemispherical) and haze (diffusion) are the two performance parameters that govern greenhouse yield, and we control both to spec, coating and tempering to the numbers your growing environment demands.
Transmittance and Haze — Tuned to Your Crop
Direct transmittance drives yield: every 1% gain in transmittance raises crop output by roughly 1%. Haze redistributes that light — diffusing it through the canopy so lower and interior leaves receive usable illumination. We deliver up to 97.5% transmittance (ISO 950:2023, 400–700 nm visible band) with haze fully selectable from 5% to 75%, matched to crop and greenhouse type:
- Low haze (5–20%) — for seedling and propagation greenhouses; direct light drives strong, healthy starts.
- Mid-to-high haze (40–75%) — for fruit and vegetable production; diffused light penetrates mid-canopy leaves and lifts lower-canopy yield by ~36%.
- Custom 5–75% — configured to each crop's optimal light distribution.
Pattern, Coating & Grade Options
- Surface patterns: single-frost, double-frost, pear-grain, cloth-grain — custom patterns available.
- AR-coated grades: base, single-side AR, and double-side AR, progressively raising transmittance.
- Iron content: ultra-low ≤150 ppm Fe₂O₃ for maximum clarity.
- Hydrophilic surface across all grades — condensation sheets off rather than dripping, protecting the canopy and preserving light transmission.
