What is a key characteristic of double-walled glazing compared to traditional single-pane glazing?

• A. Higher light transmission
• B. Lower insulation value
• C. Greater energy efficiency
• D. Less material usage

Answer: (C)

Double-walled glazing is designed to enhance thermal performance by trapping air or providing a vacuum between the two panes of glass. This construction significantly improves energy efficiency compared to traditional single-pane glazing, which allows more heat loss or gain due to its single layer of glass. The insulation properties of double-walled glazing help maintain a more stable interior temperature, reducing the need for heating and cooling systems, thereby conserving energy. In contrast, the other options do not accurately represent the advantages of double-walled glazing. Higher light transmission may be achieved by single-pane systems in certain scenarios, but it generally does not surpass the efficiency gained in energy conservation provided by the double-walled approach. With regard to insulation value, double-walled glazing inherently possesses a higher insulation value since it is designed to prevent heat transfer effectively. Lastly, double-walled glazing typically uses more material than single-pane glazing due to the additional layer, which does not correlate with less material usage. Thus, the primary advantage remains in the greater energy efficiency offered by the double-walled design.
