Which is better insulation between a glass greenhouse and a plastic greenhouse?

In the current construction of modern connected greenhouses, excluding sunlight greenhouses, glass greenhouses and plastic film greenhouses are common structural types. Which type of insulation room has better performance?

We all know that temperature is a basic condition for ensuring the normal growth of agricultural crops. A greenhouse is a type of insulated agricultural facility that creates a suitable environment for the normal and rapid growth of agricultural crops. Insulation is an important task in greenhouse agricultural production, and selecting a suitable covering material is also necessary.

In order to test which covering material has better insulation performance, we selected two greenhouses near latitude 35 degrees north for testing at the end of March, namely glass greenhouses and multi story plastic film greenhouses. Without manual heating, measure the indoor temperature every hour in two greenhouses under different weather conditions and keep records.

Through our practical analysis, we have found that plastic greenhouses have a significant increase in temperature during the day and a significant decrease in temperature at night. The insulation effect at night is not significant, while glass greenhouses have better insulation effects during the day and night than plastic greenhouses. The insulation performance of glass greenhouses is higher than that of plastic greenhouses.
