What climatic condition can double-walled glazing help mitigate in greenhouses?

Double-walled glazing is designed to improve insulation in greenhouse structures, making it particularly effective in mitigating extreme cold temperatures. This type of glazing consists of two layers of glass or plastic with an air gap in between, which serves as an insulating barrier.

When temperatures drop, this insulation helps to retain heat within the greenhouse, providing a more stable and warm environment for plants. By reducing heat loss, double-walled glazing can create conditions that support plant growth even during harsh winter months.

In contrast, while double-walled glazing may have some effects on humidity, heat retention, and wind resistance, its primary function is insulation. Therefore, it is particularly valuable in very cold climates where maintaining a warm internal environment is crucial for the health of plants.
