VGC Diffused Greenhouse Glass | High Transmittance Horticulture Diffuse Glass

1. 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.

3. Types of VGC Diffused Greenhouse Glass：

3.1 Diffuse Glass 0% Haze (2 sides AR optional)

This 0 haze diffused greenhouse glass maximizes vertical and hemispherical light transmittance, delivering sufficient light for light-loving crops in low-sunlight regions. Its surface texture evenly disperses sunlight across the greenhouse, boosting photosynthesis of lower & middle leaves to raise crop yields. Optional double-sided AR etching further lifts total light transmittance to ≥97.5%.

3.2 Diffuse Glass 5% Haze (2 sides AR optional)

3.3 Diffuse Glass 10% Haze (2 sides AR optional)

3.3 Diffuse Glass 20% Haze (2 sides AR optional)

3.3 Diffuse Glass 30% Haze (2 sides AR optional)

3.3 Diffuse Glass 40% Haze (2 sides AR optional)

3.3 Diffuse Glass 50% Haze (2 sides AR optional)

3.3 Diffuse Glass 70% Haze (2 sides AR optional)

3.3 Diffuse Glass 75% Haze (2 sides AR optional)

 

4. Diffused Greenhouse Glass vs Clear Greenhouse Glass

Most traditional greenhouses use standard clear glass, which features high light clarity but has obvious drawbacks for commercial planting. Direct sunlight through clear glass leads to overheating and sunburn on upper plant leaves, while dense crop canopies block light and leave lower leaves in long-term shadow, resulting in insufficient photosynthesis and reduced total crop yield.
VGC diffused horticulture glass perfectly optimizes this problem. It realizes uniform light scattering without sacrificing high light transmittance. The soft diffused light can penetrate deep into crop canopies, activate full-layer photosynthesis, and effectively reduce leaf temperature. Practical horticultural planting data proves that VGC diffused greenhouse glass can increase comprehensive crop yield by 10–20% compared with ordinary clear glass, making it the preferred glazing for high-value commercial greenhouses.

5. Core Advantages of VGC Diffused Greenhouse Glass

5.1 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.

5.2 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.

5.3 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.

5.4 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.

5.5 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:
  • Commercial vegetable greenhouses: Tomatoes, cucumbers, peppers, leafy greens and other high-yield crops
  • Flower planting greenhouses: Roses, carnations, orchids and various potted ornamental plants
  • Seedling breeding and tissue culture greenhouses requiring stable light environment
  • High-value berry planting greenhouses such as strawberries and blueberries
  • Large multi-span Venlo greenhouses and agricultural scientific research bases

7. 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.
