- Single Glazing: A single pane of glass. It’s a great choice for interior windows, heritage homes, or budget-conscious renovations where thermal performance isn’t a priority.
- Double Glazing: Two panes of glass with a sealed gap of argon gas between them. This design improves energy efficiency, noise reduction, and indoor comfort—making it ideal for external windows and homes exposed to traffic noise or temperature extremes.
