Why do double gazed windows provide efficient thermal insulation?

Double-glazed Windows provide efficient thermal insulation by trapping air or an inert gas between two layers of glass, creating an insulating barrier that reduces heat transfer. This design minimizes heat loss in colder months and prevents heat gain in warmer months, enhancing energy efficiency. Furthermore, the space between the panes can dampen sound transmission, contributing to improved acoustical insulation as well. Overall, double glazing effectively helps maintain a comfortable indoor temperature while reducing energy costs.
