How do I decide between single, double, or triple-glazed windows?
Single-glazing consists of a single pane of glass and is best used in garages and buildings that do not need to be extremely energy efficient. Double-glazed windows have two panes of glass with either air or a safe, colorless and odorless gas tightly sealed between the panes. When its glass is treated with Low E coating, the window can achieve a value of R5 at the center point of the glass.
