Product Introduction

The external white greenhouse screen features an innovative open-structure design with a highly reflective white surface that maximizes light diffusion and delivers soft, uniform, multi-angle illumination deep into the crop canopy. This promotes vigorous growth, better light utilization, and healthier plant development. The open mesh ensures excellent airflow, significantly reducing greenhouse and crop temperatures on hot days while providing consistent daytime shading.

At night, the screen acts as a thermal blanket, minimizing heat loss and creating a warmer microclimate around plants for more stable growth, even in regions with cold nights. Designed for tough outdoor conditions, it also protects the greenhouse from hail, heavy rain, wind, and extreme weather — offering growers a durable, energy-saving solution that improves climate control and boosts overall crop performance.

Performance Features

1. Superior Light Diffusion

Specially engineered white film strips scatter sunlight gently and evenly in multiple directions, eliminating harsh shadows and increasing light penetration throughout the canopy. This results in higher photosynthetic efficiency, stronger plants, and more balanced growth at every stage of cultivation.

2. Excellent Ventilation & Cooling

The open-weave construction promotes powerful natural airflow, preventing heat buildup, lowering humidity levels, and reducing the risk of fungal diseases. It provides effective, energy-free cooling in hot climates while maintaining a comfortable environment for crops.

3. Exceptional Durability & Long Service Life

Manufactured from UV-stabilized, co-extruded polymer strips and high-strength monofilament fibers, the screen resists intense sunlight, rain, wind, and extreme weather for many years. Minimal maintenance and consistent long-term shading performance make it ideal for professional growers.

4. Outstanding Dimensional Stability

Thermally stable design keeps the screen flat and properly tensioned even under high heat. Shrinkage remains below 2% in both directions after exposure to 70°C for 2 hours, ensuring reliable, uniform coverage season after season with virtually no adjustments needed.

5. Highly Flexible Installation & Use

Compatible with rolling, sliding, or fixed systems, it adapts easily to any greenhouse structure or climate-control setup. Perfect as an external shading and protection screen for vegetables, flowers, nurseries, young plants, and large-scale commercial operations.

Process Technology

What is 6-Guage Warp Knitting Technology?

At the heart of this product lies 6-Gauge Warp Knitting Technology, a cutting-edge textile process that combines strength, precision, and flexibility. In this system, yarns are interlaced vertically using six needles per inch, creating a dense and uniform fabric structure. The interweaving of aluminum and PET strips results in a highly durable yet lightweight climate screen with superior mechanical and optical performance.

Advantages of Warp Knitting Technology

  • High Structural Accuracy: The even distribution of yarn tension ensures consistent density and excellent dimensional stability across large areas.

  • Enhanced Durability: The dense knit pattern provides outstanding resistance to tearing, stretching, and deformation, ensuring a long operational lifespan.

  • Optimized Light Management: Precisely spaced diffusive elements scatter light evenly, promoting homogeneous illumination within the crop canopy.

  • Energy Efficiency: The reflective aluminum components minimize heat gain during the day and help retain thermal energy at night.

  • Soft and Easy to Operate: The flexible textile construction folds smoothly and occupies minimal space when retracted.

  • Fray-Resistant Cutting: The edges remain stable after trimming, allowing easy customization and installation without unraveling.

  • Secure Material Bonding: PET and aluminum layers are tightly fused to prevent delamination, ensuring reliable performance even in automated climate control systems.

This combination of material engineering and textile precision ensures that each climate screen performs consistently over years of demanding greenhouse use.

Applications in Greenhouse Cultivation

1. Efficient External Shading

Delivers powerful shading (typically 50–70% depending on weave density) that blocks excessive solar radiation, significantly reducing greenhouse temperatures by 5–10°C on the hottest days and preventing heat stress in crops during peak summer.

2. Superior Natural Ventilation

The open-mesh structure allows free air exchange even when fully deployed, promoting rapid cooling, lowering humidity, and reducing the need for mechanical ventilation or fogging systems—perfect for tropical, subtropical, and high-radiation areas.

3. Advanced Light Diffusion

Transforms direct sunlight into soft, scattered, multi-directional light that reaches lower leaves and deeper into the canopy, improving photosynthetic efficiency, minimizing shadow spots, and encouraging uniform growth, flowering, and fruit set across the entire plant.

4. Effective Nighttime Heat Retention

Acts as a thermal shield after sunset, reducing radiative heat loss by up to 35–50% and maintaining a warmer, more stable microclimate around the crop—especially valuable in desert or continental climates with large day-to-night temperature drops.

5. Comprehensive Weather & UV Protection

Built tough for outdoor exposure, it safeguards the greenhouse structure and plants from hail damage, heavy rain, strong winds, and prolonged UV degradation, extending the life of both the screen and the greenhouse covering.

6. Broad Crop Compatibility

Proven performance across diverse horticultural sectors: leafy greens and fruiting vegetables (tomatoes, cucumbers, peppers), cut flowers and potted ornamentals, propagation nurseries, young plant production, and large-scale commercial projects including cannabis and berry cultivation under protection.

Manufacturing & Quality Control

Production Process

Every roll of the Transparent Diffuse Energy-Saving Screen is produced in a fully automated weaving and lamination facility. The production process emphasizes consistency and precision—each batch undergoes strict quality checks for material integrity, shading accuracy, and tensile strength. Our in-house testing ensures that every product meets international greenhouse standards for durability, energy performance, and light transmission.
