- Extremely High Light Transmittance and Excellent Weather-ability
Top-tier light transmittance: the light transmittance of acrylic sheets can be as high as 92% or more, even superior to glass. This means it allows more sunlight into the greenhouse, providing ample light for plant photosynthesis, effectively promoting plant growth and shortening growth cycles.
Controllable UV transmittance: specially treated acrylic sheets (such as UV-transmitting panels) can allow beneficial ultraviolet light to pass through, promoting coloration in certain crops (for example: making flowers more vibrant or increasing fruit sugar content). Conversely, other types can block harmful UV rays to protect specific plants.
Anti-yellowing and aging: high-quality acrylic sheets come with a UV-resistant coating that effectively resists degradation caused by solar ultraviolet radiation. Even with long-term outdoor exposure, they are not prone to yellowing, hazing, or becoming brittle like ordinary plastics. They can maintain high light transmittance over the long term, with a service life of up to 10 years or more.
- Excellent Impact Resistance and High Safety
“Unbreakable glass”: the impact resistance of acrylic is 10-20 times that of ordinary glass, making it a safe alternative to glass of the same thickness.
Safety: even if it breaks under significant impact, acrylic sheets do not shatter into sharp fragments like glass. This reduces the risk of injury to personnel and avoids contamination and damage to crops from debris. This is particularly important for coping with extreme weather conditions such as hail and strong winds.
- Outstanding Thermal Insulation Properties
Low thermal conductivity: the thermal conductivity of acrylic (about 0.19 W/m·K) is lower than that of glass, meaning it has better insulation properties.
Energy savings: In winter, it better retains heat inside the greenhouse, reducing heating energy consumption. In summer, it can also somewhat slow down the ingress of external heat, helping to maintain a more stable indoor environment and reduce cooling costs.
- Lightweight and Easy to Process and Install
Light weight: the density of acrylic sheets is about half that of glass, and they weigh only 50% of glass of the same specification. This allows the main structure of the greenhouse to be designed lighter, reducing the construction cost of the framework and foundation requirements, while also making transportation and installation more convenient and labor-saving.
Good processability: acrylic sheets can be easily cut, drilled, bent, ect, allowing flexible adaptation to various greenhouse design shapes, such as arches and curves.
- Good Chemical Stability and Corrosion Resistance
Good resistance to general chemicals such as acids and alkalis. They can withstand corrosion from common fertilizers, pesticide sprays, etc., in the greenhouse environment and are not easily degraded. The smooth surface is not prone to dust accumulation and can be cleaned by rainwater, making maintenance easy.
In conclusion, it is high light transmittance, impact resistance, long lifespan, and excellent thermal insulation, acrylic sheets are an ideal choice for building high-performance, modern outdoor greenhouses, especially suitable for high-end agricultural applications seeking long-term return on investment.
