What Is Diffused Greenhouse Glass?
VGC Diffused greenhouse glass is a professional horticultural glazing material designed for modern commercial greenhouses. Different from ordinary clear greenhouse glass that emits harsh direct sunlight, VGC diffused greenhouse glass adopts professional physical texturing technology to scatter intense solar rays into soft, uniform diffused light.
This advanced horticulture glass effectively eliminates light hotspots and sharp shadows inside greenhouses, balancing indoor light and temperature. It creates a stable, crop-friendly growing environment, solving the core planting pain points of uneven growth and leaf sunburn caused by unreasonable light distribution. As a reliable manufacturer, VGC provides customized diffused glass with multiple haze levels and AR coating solutions to adapt to different crops and global climate conditions.
1. Diffuse Glass Low Haze (0%/5%/10%/20%/30%) with 2 sides AR optional
VGC low-haze diffused glass maximizes summer light efficiency. Its textured surface evenly spreads light to prevent crop heat damage. Double-sided AR coating preserves winter light and consistent yields.
2.Diffuse Glass Medium Haze (40% and 50%) with 2 sides AR optional
VGC medium-haze diffused glass balances light transmittance and scattering for optimal sunlight efficiency.Its surface pattern distributes sunlight evenly across greenhouses and prevents crop scorching & wilting from extreme heat.Dual-side AR etching is optional to achieve ≥97.5% light transmittance.
3.Diffuse Glass High Haze (70% and 75%) with 2 sides AR optional
VGC high-haze diffused glass optimizes sunlight utilization, ideal for bright summer conditions.Its surface texture evenly distributes light across greenhouses, avoiding crop scorching and wilting under intense summer heat.Dual-side AR coating is recommended to retain ample winter light and stable yields.

Diffused Greenhouse Glass vs Clear Greenhouse Glass
Standard clear greenhouse glass causes leaf sunburn and deep canopy shadows, weakening photosynthesis and lowering yields.
VGC diffused glass evenly spreads light without losing transmittance. Soft light penetrates full crop layers to cool leaves and boost photosynthesis, lifting overall yields by 10–20% — the top choice for high-value commercial greenhouses.
| Comparison Item | Diffused Greenhouse Glass | Clear Greenhouse Glass |
|---|---|---|
| Light Distribution | Evenly scattered light, covers full canopy top to bottom | Direct vertical light, concentrated only on top leaves |
| Crop Penetration | Deep penetration into mid & lower leaves | Limited to upper canopy, shadows underneath |
| Shadow Effect | Minimal soft shadows inside greenhouse | Strong hard shadows under plants & structures |
| Summer Heat Risk | Diffused light reduces leaf burn & crop stress | Intense direct light causes scorching & wilting |
| Winter Performance | High hemispherical LT captures more angled sunlight | Only high direct LT, low efficiency in low sun angle |
| Photosynthesis | Higher overall — all leaf layers contribute | Lower — only top leaves fully active |
| Yield Output | 10–25% higher uniform growth across the greenhouse | Uneven growth, taller plants shade shorter ones |
| Self-Cleaning | Available with hydrophilic AR coating (anti-drip) | Standard clear glass, condensation drips directly |
| Best For | High-light crops, multi-layer plants, year-round production | Low-light regions, single-layer short crops |
| Haze Level | 0% – 75% adjustable options | 0% haze (fully clear) |
Core Advantages of VGC Diffused Greenhouse Glass
1. Uniform Light Distribution, No Crop Heat Stress
VGC diffused greenhouse glass features permanent surface diffusion treatment, which evenly disperses concentrated sunlight. It completely avoids local overheating and leaf sunburn caused by midday strong light, eliminates planting dead angles with insufficient light, and ensures consistent growth of all plants. This advantage is particularly prominent in high-temperature and strong-light areas.
2.Ultra-High Light Transmittance for Higher Yield
Different from inferior diffused glass that blocks light, VGC diffused horticulture glass adopts high-quality low-iron glass substrate, matched with double-sided AR anti-reflective coating. The comprehensive light transmittance can reach up to 97.5%. While realizing uniform light diffusion, it maximizes the utilization rate of solar energy, accelerates crop growth cycles, and significantly improves the yield and quality of vegetables and flowers.
3.Self-Cleaning & Low Maintenance Cost
The AR hydrophilic coating equipped on VGC diffused greenhouse glass has excellent self-cleaning performance. Rainwater forms a uniform water film on the glass surface to take away dust and impurities, avoiding water droplet accumulation and light attenuation caused by dirt coverage. It greatly reduces manual cleaning frequency and long-term operation and maintenance costs of greenhouses.
4. High Weather Resistance & Ultra-Long Service Life
All VGC diffused greenhouse glass is fully tempered in strict accordance with EN12150 international safety standards. It has strong wind resistance, hail resistance and impact resistance, adapting to extreme weather such as strong winds, heavy snow and hail. The physical diffusion texture will not fade or age under long-term UV irradiation, with a stable service life of 25–30 years, far exceeding traditional plastic shading films and ordinary glass.
5.Customized Solutions for Global Market Demands
To meet the differentiated needs of global importers and growers, VGC provides two iron content formulas for diffused greenhouse glass: low-iron glass for ultra-high light transmission planting scenarios, and medium-iron glass that complies with EU anti-dumping policies, helping European customers effectively reduce procurement costs while ensuring stable performance.
6. Main Application Scenarios
VGC high-performance diffused greenhouse glass is widely recognized by commercial growers around the world and is suitable for all types of high-end agricultural greenhouses:
-

8. Frequently Asked Questions
Q1: Is diffused greenhouse glass more suitable for commercial planting than clear glass?
Yes. For large-scale commercial horticulture, diffused greenhouse glass can balance light distribution, avoid crop sunburn and heat stress, and significantly improve overall yield. Clear glass is only suitable for simple planting scenarios and cannot meet the high-efficiency planting needs of modern commercial greenhouses.
Q2: Will diffused glass reduce greenhouse light transmittance?
High-quality VGC diffused glass will not cause effective light loss. With low-iron substrate and double-sided AR coating, its light transmittance is as high as 97.5%. It only scatters sunlight rather than blocks it, realizing higher light utilization efficiency than ordinary clear glass.
Q3: How to choose the right haze level?
20% low haze is suitable for high-latitude cold areas and light-loving fruit and vegetable crops; 50% medium haze is a universal model, suitable for most flowers and vegetable greenhouses; 70% high haze is suitable for high-temperature and strong-light areas and light-sensitive leafy vegetables and berries.
Q4: What is the service life of VGC diffused greenhouse glass?
Under normal use and daily maintenance, VGC fully tempered diffused greenhouse glass has a service life of 25–30 years, with extremely low light attenuation rate, stable long-term performance and no frequent replacement required.
