Benefits of Double-Glazing Windows

How do Double Glazed windows work?

double-glazing windows work by trapping a layer of air or gas between two panes of glass. This layer acts as an insulator, preventing heat from escaping or entering your home. The space between the glass panes is filled with either air or an inert gas such as argon or krypton, which further enhances the insulating properties.

The spacer bar, typically made of aluminum or uPVC, holds the glass panes apart and creates an airtight seal. This seal prevents moisture from entering the gap and ensures the longevity and effectiveness of the double-glazed unit.
