Product Introduction

The Transparent Diffuse Energy-Saving Screen represents a new generation of greenhouse climate control materials, engineered to deliver optimal balance between light management, energy conservation, and crop protection. Developed using advanced high-diffusion polymer technology and precision warp knitting, this screen transforms the way sunlight enters and interacts with the greenhouse environment.

Unlike conventional transparent films, this innovative screen softens incoming sunlight and scatters it uniformly across the plant canopy. The result is a well-balanced distribution of light that eliminates sharp shadows and minimizes the risk of heat buildup or scorching on delicate leaves and fruits. Crops receive sufficient illumination from multiple directions, leading to stronger photosynthetic activity, improved uniformity in growth, and higher yields across production cycles.

At night, when the screen is fully closed, it functions as a highly effective thermal barrier. By preventing the rapid escape of accumulated heat, it keeps internal temperatures stable and reduces the likelihood of condensation on plant surfaces—a major cause of fungal diseases and physiological stress. This dual-purpose performance—diffused daylight regulation and nighttime insulation—makes it an essential component in energy-efficient greenhouse systems.

Performance Features

1. Superior Thermal Insulation & Energy Efficiency

The transparent diffuse screen effectively retains thermal energy inside the greenhouse, maintaining warmth during the night and minimizing heat loss through radiation. During the day, its excellent optical clarity allows optimal sunlight penetration without sacrificing insulation. The result is reduced heating costs in winter and improved cooling efficiency during warmer months—offering year-round energy savings.

2. Excellent Breathability

Designed with a breathable knitted structure, the screen allows water vapor to pass freely. This prevents moisture from accumulating beneath the fabric, thus reducing the risk of condensation, algae, and moss formation. Enhanced air exchange supports a healthier microclimate and consistent humidity levels, particularly beneficial for sensitive crops such as tomatoes, cucumbers, and flowers.

3. High-Performance Light Diffusion

The screen’s unique combination of transparent and diffusive strips ensures even light scattering throughout the greenhouse. This uniform illumination helps plants receive consistent radiation regardless of their position, eliminating hotspots and ensuring balanced canopy temperature. By reducing direct glare and overheating, it enables growers to maintain optimal light conditions for photosynthesis without compromising plant comfort.

4. UV Resistance & Self-Cleaning Surface

Made from high-quality PET yarns, the screen features excellent resistance to UV degradation. Added anti-static properties help prevent dust accumulation, keeping the surface cleaner for longer. Even after extended exposure to sunlight and agricultural chemicals, the material retains its optical properties, ensuring consistent light transmission and a long service life.

5. Reliable Stability & Dimensional Integrity

Each screen is formulated with UV stabilizers and heat-resistant polymers to withstand harsh greenhouse environments. It resists common agrochemicals, fertilizers, and cleaning agents without loss of strength or elasticity. Laboratory testing shows a heat shrinkage rate of less than 2.0% after two hours at 70°C—evidence of exceptional dimensional stability.

6. Flexible & Space-Saving Design

The knitted construction gives the material remarkable flexibility and softness, allowing it to fold compactly when retracted. This design minimizes shading when the screen is open, maximizing sunlight access. The light, pliable texture also simplifies installation and maintenance, reducing mechanical strain on rolling systems.

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

The Transparent Diffuse Energy-Saving Screen is designed to integrate seamlessly into a variety of modern greenhouse structures—from high-tech glass facilities to multi-span film houses. Its adaptable installation options make it suitable for both new constructions and retrofit projects.

In practice, growers often pair this screen with an inner white diffusive climate screen. This combination enhances seasonal efficiency: during summer, the dual-screen setup improves shading and cooling by reducing solar radiation intensity; during winter, the combined layers provide superior insulation, trapping warmth and stabilizing nighttime temperatures. The synergy between diffusion and insulation ensures that plants receive the best possible environmental conditions year-round.

Whether used for vegetables, ornamentals, or nursery crops, this system supports uniform light distribution, consistent humidity control, and optimal energy balance—key factors for achieving high-quality produce and maximizing return on investment.

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.
