In modern greenhouse cultivation, environmental control is everything. Whether you grow vegetables, flowers, or young seedlings, maintaining the right temperature, light level, and humidity directly affects both crop quality and yield. As energy costs rise and growers seek more sustainable solutions, greenhouse climate screens have become one of the most essential tools for achieving stable and efficient growing conditions.
A climate screen is more than a simple shading net. It is an advanced knitted system engineered to regulate light transmission, temperature, and humidity inside a greenhouse. By automatically opening or closing in response to environmental changes, climate screens help create an ideal microclimate for plant growth — while also reducing energy consumption.
A greenhouse climate screen is a specially knitted fabric made from polyester yarns and aluminum foil strips. Unlike ordinary shade cloths, climate screens combine multiple functions in one system:
Shading and light diffusion
Thermal insulation and energy saving
Condensation control
Photoperiod management
Installed horizontally or vertically inside the greenhouse, the screen system can be manually or automatically operated. During the day, it reduces excessive solar radiation and protects plants from heat stress; at night, it minimizes heat loss by reflecting longwave radiation back into the greenhouse.
Modern greenhouse operators consider the climate screen a key component of smart greenhouse systems. Integrated with climate computers, the screen can respond to light intensity, temperature, or time settings — creating an adaptive, energy-efficient growing environment.
Energy costs are one of the largest expenses in greenhouse operations. A closed climate screen forms a thermal barrier that traps heat during the night and reduces the need for additional heating. Tests show that a high-quality energy-saving screen can reduce heat loss by 40–60%, depending on the material type and installation method.
The aluminum foil layer reflects longwave infrared radiation back toward the crop area, keeping temperatures stable even in cold weather. This not only saves fuel costs but also helps maintain consistent plant growth and uniform crop quality.
Light is essential for photosynthesis, but too much sunlight can damage sensitive crops or cause excessive transpiration. Climate screens are designed to filter and diffuse sunlight evenly throughout the greenhouse. The result is a softer, more uniform light that reaches lower canopy levels, reducing shade zones and improving overall plant development.
Different screen types offer different shade percentages, usually ranging from 15% to 85%. Growers can choose the right level based on their crops, climate zone, and greenhouse structure. For example:
Aluminized screens: Reflect solar radiation and reduce heat buildup.
White diffusive screens: Soften and spread light evenly.
Blackout screens: Control day length and photoperiod for flowering crops.
When warm, moist air meets a cold greenhouse roof, condensation can occur — leading to dripping water and fungal diseases. Climate screens help balance temperature differences between the crop area and the roof, significantly reducing condensation risks. Some screens are semi-open to allow gentle air exchange, preventing humidity buildup under the screen.
By maintaining a more stable humidity level, the screen helps reduce the risk of mildew, botrytis, and other common greenhouse diseases.
The combination of balanced light, temperature, and humidity creates a more stable microclimate for plants. Crops grow more uniformly, with fewer stress factors and better physiological performance. Growers often observe shorter production cycles, higher yields, and better color quality in flowers and fruits.
Climate screens also help extend the growing season. By maintaining warmth during cool nights and protecting from extreme sunlight during hot days, they enable year-round production in both cold and warm regions.
With growing awareness of climate change, energy efficiency has become a priority for greenhouse operations. By lowering heating and cooling demands, climate screens directly contribute to reducing carbon emissions.
In large-scale commercial greenhouses, even a small percentage of energy savings translates into significant cost and carbon reductions. For modern growers, installing a climate screen is both an environmental and economic investment.
| Type | Main Function | Typical Application |
|---|---|---|
| Shading Screen | Reflects sunlight, prevents overheating | Summer crops, tropical zones |
| Energy-Saving Screen | Retains heat, reduces night energy loss | Winter and cold climates |
| Blackout Screen | Blocks light completely for daylength control | Flowering plants (e.g. chrysanthemum, poinsettia) |
| Diffusion Screen | Softens light, improves canopy distribution | Vegetable and seedling greenhouses |

Growers often combine multiple screens or use double-screen systems to achieve both shading and insulation benefits depending on the season.
High-quality greenhouse climate screens are produced through advanced knitting technology, rather than traditional weaving. This knitted structure gives the screen flexibility, durability, and uniform shading performance while maintaining a lightweight design suitable for large-span greenhouses.
Each screen is made from a combination of polyester (PET) and aluminum strips, precisely engineered to achieve specific shading, light diffusion, and energy-saving effects. Different screen models are designed with customized combinations of yarn and foil strips, allowing growers to select the ideal balance of light transmission, reflection, and ventilation for their crops and climate zone.
The polyester yarns provide high tensile strength, dimensional stability, and excellent resistance to UV radiation and humidity. The aluminum strips reflect excess solar radiation during the day and help retain heat at night, greatly improving the energy efficiency of the greenhouse.
This knitting process ensures smooth, seamless joints that resist fraying and enable long service life under intensive daily operation. Compared to ordinary woven shade cloths, knitted climate screens offer more stable optical performance, better flexibility, and superior resistance to wear and tear — similar to the advanced technology used by leading European brands such as Svensson.
In high-tech greenhouses, climate screens are fully integrated into climate control systems. Through sensors and software, the screens can automatically adjust based on light intensity, temperature, humidity, or time schedules.
For example:
The screen opens gradually in the morning as light increases.
It closes during midday peaks to reduce solar load.
At night, it shuts completely to conserve heat.
This smart control not only improves crop uniformity but also reduces labor costs and human error. Growers can fine-tune settings remotely via computer or mobile app, achieving precise environmental management.
Climate screens are widely used across different greenhouse crops:
Vegetables: Tomatoes, cucumbers, and peppers benefit from stable light and temperature, leading to faster growth and higher yields.
Flowers: Roses, chrysanthemums, and orchids require strict light and photoperiod control for uniform blooming.
Seedlings: Young plants are sensitive to light intensity and temperature fluctuations, making screens vital for healthy propagation.
Leafy greens: Lettuce and herbs prefer diffused light for compact growth and better color quality.
