Product Introduction

The black-and-white external shade screen is designed to optimize greenhouse climate control with a dual-color structure. The white upper surface reflects strong sunlight while diffusing incoming rays, improving light distribution and increasing the overall shading rate. The black underside reduces thermal radiation loss from plants, helping maintain a more stable growing temperature.

Its open structure enhances ventilation and cooling performance, effectively lowering both greenhouse and crop temperatures during high-radiation periods. This balanced climate supports healthier plant development and reduces heat stress.

In addition, the screen provides dependable protection against extreme weather. It helps safeguard greenhouses and crops from hail, heavy downpours, and other harsh outdoor conditions, ensuring safer and more consistent cultivation.

Performance Features

1. Open-Knitted Structure

The open-knitted design allows continuous airflow, ensuring maximum ventilation between the greenhouse interior and the outside environment. This structure helps maintain a more balanced climate and prevents excessive heat buildup.

2. Significant Cooling Effect

The external shade screen protects crops from direct solar radiation while helping regulate overall greenhouse temperature. Its white upper surface effectively reflects sunlight, reducing heat stress on crops and creating a cooler, more stable growing environment during hot periods.

3. Reduced Nighttime Heat Loss

At night, the screen minimizes thermal radiation from the greenhouse to the outside. This helps maintain a warmer internal climate, reduces heat loss in crops, and significantly lowers the risk of frost damage, especially during cold seasons.

4. Long Service Life

Constructed from co-extruded polymer film strips woven together with high-strength monofilament fibers, the screen offers excellent durability. This advanced material combination enables it to withstand strong winds, UV exposure, and other harsh weather conditions, delivering a longer service life.

5. Long-Lasting Cleanliness

With high UV resistance and anti-static performance, the screen repels dust and maintains cleanliness even after prolonged use. This ensures consistent shading efficiency and reduces maintenance requirements over time.

6. Outstanding Dimensional Stability

The product maintains stable dimensions under thermal stress. After exposure at 70°C for 2 hours, both longitudinal and transverse shrinkage remain below 2.0%, ensuring reliable performance and a consistent fit in installation systems.

7. Versatile Application Methods

The screen is compatible with various installation systems, including roll-up mechanisms, sliding systems, and fixed mounting options. This flexibility makes it suitable for different greenhouse structures and climate control setups.

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. High-Light Regions & Hot Climates

Ideal for greenhouses in high-radiation areas, the black and white external shade screen reduces excessive solar gain and stabilizes greenhouse temperature, improving overall climate control.

2. Vegetable & Fruit Greenhouses

Widely used for tomatoes, cucumbers, peppers, berries, and leafy greens. The screen lowers heat stress, enhances light diffusion, and creates a more uniform canopy environment for higher-quality yields.

3. Ornamental Plant & Flower Production

The increased shading rate and diffuse light effect help prevent leaf burn, improve color development, and support consistent growth for flowers, potted plants, and decorative foliage crops.

4. Seedling Nurseries & Young Plant Protection

Provides optimal shading and thermal stability for seedlings, reducing transplant shock and promoting strong early-stage development in nurseries and propagation houses.

5. Climate Protection & Weather Resistance

The durable black-and-white shade screen protects greenhouses from hail, heavy downpours, and strong winds, reducing risks in regions with unstable or extreme weather conditions.

6. Energy-Saving Greenhouse Operations

By reflecting excess sunlight and reducing thermal radiation loss, the screen supports energy-efficient climate management while maintaining more stable day and night temperatures.

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.
