In modern greenhouse cultivation, growers are constantly seeking ways to create the most balanced growing environment — one that ensures optimal light distribution, stable temperature, and high energy efficiency.
Among all climate control solutions, the combination of a transparent energy-saving screen and a white diffuse screen has proven to be one of the most effective systems for achieving these goals.
This dual-screen setup allows greenhouses to adapt to varying light and temperature demands throughout the year, providing both maximum light transmission and excellent thermal insulation.
The transparent energy-saving screen is made from high-transmission PET strips using advanced warp-knitting technology.
Unlike reflective or aluminum-coated screens, this model is purely transparent, allowing light to pass through with minimal loss while still creating an insulating barrier that reduces heat exchange between the greenhouse interior and the outside environment.
Transparent Energy-Saving Screen (clear)
Transparent Energy-Saving Screen (Diffuse)
High light transmission
Ensures crops receive sufficient natural sunlight even during cloudy or short-day seasons.
Thermal insulation
Minimizes nighttime heat loss and stabilizes temperature fluctuations.
Breathable knitted structure
Allows air and moisture to pass through, reducing condensation risk.
Compact folding
Soft and flexible knitting makes it easy to retract with minimal stacking volume.
This type of screen is especially valuable during winter and early spring, when light is limited and maintaining warmth is critical for crop health and energy efficiency.
The white diffuse screen is designed to scatter incoming sunlight, providing uniform illumination throughout the greenhouse canopy.
Made from white PET or polyester strips, this screen reflects and diffuses strong direct radiation, protecting sensitive crops from overheating or light burn.
White Diffuse Screen (closed cell)
White Diffuse Screen (open cell)
Diffuse light effect
Evenly distributes sunlight to lower leaves and shaded areas.
Temperature control
Reduces the risk of hot spots and helps maintain consistent crop temperature.
Improved crop uniformity
Enhances photosynthetic efficiency and promotes balanced plant growth.
Available in different versions
Open or closed structure, with optional flame-retardant materials depending on greenhouse requirements.
White diffuse screens are commonly used in summer and bright climates, helping growers maintain crop quality under high light conditions.
When used together, the transparent and white diffuse screens complement each other's strengths.
This overlapping dual-screen system allows the grower to dynamically control light and temperature according to seasonal changes, crop stages, and daily weather fluctuations.
Below are the major advantages of combining both:
Summer
The white diffuse screen can be drawn to reduce excessive radiation and prevent overheating, while the transparent screen remains open to ensure airflow.
Winter
The transparent screen is used during cold nights to retain heat, keeping energy consumption low without reducing light levels during the day.
Spring & Autumn
Both screens can be adjusted independently or together, offering complete control over light intensity and heat retention.
This flexibility makes the dual-screen setup ideal for year-round greenhouse operation in diverse climates.
The white diffuse screen breaks down intense direct sunlight into scattered light, ensuring that lower leaves and shaded areas also receive illumination.
Meanwhile, the transparent screen ensures that overall light quantity remains high, maximizing the photosynthetic potential of the crops.
Together, they create a balanced light environment — soft yet bright — which results in:
Reduced leaf temperature and light stress
Enhanced photosynthetic efficiency
Better color and size uniformity of fruits and flowers
The transparent screen acts as a thermal barrier, trapping warm air during the night and minimizing heat loss through convection.
When both screens are closed, an additional air layer forms between them, significantly improving insulation performance.
Research and field experience show that dual-screen systems can reduce heat loss by up to 40–50%, translating directly into lower heating costs and more stable nighttime conditions.
Excess moisture and condensation are common issues in greenhouse environments, leading to dripping, disease, and mold.
The breathable knitting structure of the transparent screen allows vapor to pass through instead of accumulating under the fabric.
When combined with the white diffuse screen, the result is a drier, more stable microclimate above the crops — minimizing condensation and improving crop health.
This dual-screen combination can be installed using either:
Screen support wire sliding systems, or
Hanging installation systems,
depending on greenhouse structure and design.
Both types are compatible with automated climate control systems, allowing the screens to open or close in response to temperature, light, or humidity sensors — ensuring intelligent energy management and consistent growing conditions.
The combination of transparent and white diffuse screens is suitable for various greenhouse types:
Glass greenhouses
Polycarbonate panel greenhouses
Film or plastic greenhouses
It is widely used in high-value crops such as:
Tomatoes, cucumbers, and peppers
Strawberries and leafy greens
Orchids, roses, and other ornamental plants
Growers in northern regions or high-altitude areas benefit from improved insulation during cold nights, while those in tropical or sunny climates appreciate the diffused light and cooling effect during hot days.
| Aspect | Single Screen | Dual Screen (Transparent + Diffuse) |
|---|---|---|
| Light Transmission | High or Moderate | High and Even |
| Diffusion Effect | Limited | Excellent |
| Heat Retention | Medium | Strong |
| Condensation Control | Moderate | Enhanced |
| Seasonal Flexibility | Limited | Excellent |
| Energy Saving | 15–25% | Up to 50% |
This table highlights how the dual-layer approach outperforms single-screen systems in nearly all critical climate control aspects.
The combination of transparent and diffuse screens reflects the direction of next-generation greenhouse technology — moving toward smarter, more sustainable, and more precise climate control.
By integrating automated screen systems with sensors for light, temperature, and humidity, growers can optimize crop growth conditions in real time, saving energy while improving yields.
The dual-screen system is not just a product upgrade — it is an energy-saving strategy and a crop-quality solution that benefits both productivity and sustainability.
Using a transparent and a white diffuse screen together offers greenhouse growers the best of both worlds:
Maximum daylight utilization
Uniform light distribution
Excellent heat retention
Flexible seasonal operation
Energy and cost savings
As greenhouse production continues to evolve toward higher efficiency and climate adaptability, the dual-screen system has become a standard for professional, energy-conscious growers worldwide.
