What is Double Glazing?

Double glazing involves 2 panes of glass sealed together to create an insulating air area in between them. This construction offers many advantages:

• Energy Efficiency: Reduces heat loss in winter and heat gain in summer season.
• Sound Reduction: Diminishes external sound contamination.
• Condensation Prevention: Lowers the chances of condensation forming on the inner surface areas of windows.

The Anatomy of a Double Glazed Window

Let's very first understand the structure of a double-glazed window with the following table:

Component	Description
Outer Pane	The external layer exposed to the aspects.
