Product Introduction

Internal aluminum screens are engineered with high-reflective aluminum strips and transparent polymer materials to deliver superior climate control. Their reflective properties enhance daylight cooling while significantly reducing nighttime heat loss from crops, allowing growers to achieve excellent energy savings at any given shading rate.

With an open-structure design, these screens promote efficient cooling in greenhouses equipped with roof ventilation. They improve shading performance, optimize airflow, and create a stable climate environment that is especially beneficial for sensitive plants requiring precise temperature management.

Built to meet the highest safety standards in the horticultural industry, internal aluminum screens provide reliable long-term performance and enhanced crop protection. By maintaining higher plant temperatures at night and reducing energy consumption, they support year-round efficiency for modern greenhouse operations.

Performance Features

1. Reflection

Special aluminum foil and polyester materials provide excellent radiation, reflection, and transmission performance. They effectively cool the greenhouse during the day and retain heat at night, creating a favorable indoor climate while reducing energy costs.

2. Humidity Control & Anti-Condensation

The woven structure allows sufficient water vapor to pass through, preventing condensation from forming beneath the screen.

3. Long Service Life

Made with highly UV-resistant and anti-static materials, the screen remains clean and effective after long-term use. UV stabilizers added to the material provide resistance to commonly used greenhouse chemicals.

4. Stable Performance

A special formulation and manufacturing process, combined with high-quality pure aluminum foil, ensure the product will not experience aluminum detachment. The shrinkage rate remains ≤1% even at 70°C.

5. Proven Outdoor Durability

The special woven structure makes the screen easy to fold, ensuring maximum utilization of light resources when the shading screen is retracted.

6. Seamless System Integration

Suitable for all types of greenhouses and compatible with various greenhouse covering materials. Installation options include support-wire sliding systems and hanging systems.

Comparison with Other Screens

Comparison of Internal Greenhouse Shading Screens: White, Aluminum, Blackout

Feature  White Screen Aluminum Screen
Blackout Screen
Material & Structure Knitted polymer threads with white coating Special aluminum strips combined with transparent polymer in knitted structure Opaque knitted fabric, often polyester or PVC-based
Shading & Light Control Diffuses sunlight evenly, moderate shading Reflects sunlight efficiently, moderate to high shading depending on design Blocks nearly all light, total shading
Cooling Performance Reduces heat buildup by diffusing light Reflective aluminum strips and open knitted structure improve daytime cooling Minimal cooling effect; mainly blocks sunlight
Nighttime Energy Saving Limited heat retention Reduces heat loss from crops at night, highly energy-efficient High heat retention but can trap humidity; less breathable
Impact on Crop Growth Supports uniform growth and prevents scorching Balances cooling and heat retention, ideal for sensitive or high-value crops Suitable for dark treatment or night shading; may stress light-sensitive crops if overused
Durability & Maintenance Moderate; prone to dust accumulation Highly durable, UV-resistant, anti-static Durable, easy to clean, may fade over time
Best Applications General shading, summer cooling Energy-saving internal shading, year-round temperature control Total light blocking, dark treatment, or winter energy conservation
Cost Generally lower Moderate to high Moderate

Summary:

  • White knitted screens are ideal for moderate shading and even light diffusion, suitable for general crops.

  • Knitted aluminum screens offer the best combination of shading, cooling, and nighttime energy savings, perfect for sensitive or high-value crops.

  • Blackout knitted screens provide total light blocking, ideal for night shading or dark-treatment applications, but less effective for daytime cooling.

Applications in Greenhouse Cultivation

1. Energy-Saving Climate Control

Internal aluminum screens are widely used to reduce nighttime heat loss and maintain stable temperatures around crops. Their reflective aluminum strips help growers cut heating costs during colder seasons while ensuring plants remain in an optimal thermal environment.

2. Daytime Cooling and Light Management

By reflecting excess solar radiation, these screens help control light intensity and prevent heat stress during hot days. They create a balanced light climate that supports uniform crop growth, especially for light-sensitive varieties.

3. Ideal for Sensitive and High-Value Crops

The open-structure design improves air circulation, making it suitable for crops that require precise temperature and humidity control—such as tomatoes, cucumbers, strawberries, leafy greens, ornamental plants, and young seedlings.

4. Enhanced Greenhouse Ventilation Performance

When used with roof-ventilated greenhouses, internal aluminum screens increase cooling efficiency by promoting airflow while still providing shading. This is especially useful in warm regions or during peak summer periods.

5. Climate Optimization in High-Tech Greenhouses

These screens are commonly installed in automated Venlo, polycarbonate, and glass greenhouses where climate control systems work together with shading screens to maintain consistent growing conditions.

6. Year-Round Production Support

Internal aluminum screens enable growers to extend production seasons, reduce climate fluctuations, and achieve consistent yields throughout the year, even under extreme weather conditions.

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.
