What type of arrangement do double glazed skylights typically have?

Double glazed skylights are designed to provide insulation and energy efficiency by having two layers of glass with an air or inert gas space in between. This configuration is heretically sealed to create an insulating barrier that minimizes heat loss or gain. The hermetic sealing helps prevent moisture buildup and ensures that the air within the cavity does not circulate, which optimizes thermal performance and reduces the potential for condensation.

While some skylights may allow for ventilation, double glazed units are most commonly hermetically sealed to maximize their energy efficiency. The design provides structural support and stability, and while flexibility and adjustability might refer to certain types of skylights, it is not a standard feature of double glazed models. Therefore, the correct understanding of double glazed skylights primarily focuses on their sealing properties and the thermal benefits that arise from such an arrangement.
