Describe the different types of window glass, such as singleglazed, doubleglazed, and tripleglazed, and discuss their insulating properties.
Singleglazed windows have one layer of glass, doubleglazed windows have two layers of glass separated by an air space, and tripleglazed windows have three layers of glass separated by two air spaces. Double and tripleglazed windows provide better insulation and energy efficiency by reducing heat transfer through the glass.
