Double vs Triple Glazed Windows: Which is Better for Villas?

May Wed, 2024

What is Double-Glazed Window?

Double-glazed windows consist of two glass panes placed within a frame. A gas or air pocket between the glass enhances insulation in a room. This type of window is typically referred to as a double-glazed window. Double-paned windows have become increasingly popular in both new construction and window replacements. 

What is Triple-Glazed Window?

Because of their three-pane design, triple-glazed windows provide more insulation than double-glazed ones. The two air spaces that differentiate triple glazing from double glazing are unique. This design decision drastically lowers heat transmission. Double-glazed units may also benefit from more significant air gaps and better insulation from cold air.
