- Energy Efficiency: Reduces heat loss in winter and heat gain in summer season.
- Sound Reduction: Diminishes external sound pollution.
- Condensation Prevention: Lowers the opportunities 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 |
|---|---|
