The use of 4mm thick glass in a glass greenhouse is primarily based on a combination of factors: light transmittance, cost-effectiveness, safety, and practical application. The following is a detailed analysis:
1:Light Transmittance
One of the primary functions of a glass greenhouse is to provide sufficient light for plants. 4mm thick glass typically has a high light transmittance, ensuring that plants within the greenhouse receive sufficient light, thereby promoting photosynthesis and growth.
Compared to 5mm thick glass, 4mm glass typically has a light transmittance that is approximately 1% higher. While this difference may seem insignificant, in greenhouse cultivation, even a small increase in light transmittance can have a significant impact on crop yield and quality.
2:Economical
From a cost perspective, 4mm thick glass is generally more economical than 5mm thick glass. This helps reduce greenhouse construction and operating costs, improving return on investment.
In practice, 4mm glass is sufficient to meet the light and structural safety requirements of most planting greenhouses, nursery greenhouses, and research greenhouses, eliminating the need to choose thicker glass.
3:Safety
4mm thick tempered glass has demonstrated excellent safety. Tests such as heavy ball drop tests and sandbag impact tests have shown that 4mm tempered glass can withstand impact forces nearly equivalent to 5mm tempered glass, and its ability to withstand snowstorms is virtually identical.
Using 4mm thick tempered glass on the greenhouse roof ensures both light transmittance and structural safety.
4:Practical Application Considerations
In greenhouse cultivation, in addition to light transmittance and safety, factors such as greenhouse insulation, weight, transportation, and greenhouse load-bearing capacity must also be considered. While 5mm thick glass may have a slight advantage in insulation, this advantage is not significant compared to the increased insulation provided by 4mm glass.
Furthermore, 4mm thick glass offers advantages in weight, transportation, and greenhouse load-bearing capacity, helping to reduce greenhouse construction and operating costs.
The diffuse glass and AR-coated diffuse glass produced by Yuhua have cooperated with many large commercial greenhouses in agriculture, horticulture, nurseries and experiments. We have cooperated with large greenhouse project companies such as Havecon, Van Der Hoeven, Kubo, etc. for many years. Yuhua greenhouse glass has a light transmittance of up to 99%, and haze 5/10/20/30/50/70/75 greenhouse diffuse glass is available!
