How Double-Glazed Windows Work

Double-glazed windows are made up of:

1. Two Glass Panes

Any type of glass can be used, including clear glass, tinted glass, laminated glass, or Low-E glass.

2. Spacer

Available in sizes from 6mm to 20mm, creating the insulating gap.

3. Gas Fill

The spacer is filled with air or argon gas to reduce heat transfer.

4. Sealed Unit

The entire unit is hermetically sealed to prevent moisture and dust from entering.

This design helps maintain consistent indoor temperatures, reduce energy bills, and improve acoustic insulation.
