What other factor, alongside efficiency rating, can impact a window's overall energy efficiency?

Whether the casement window opens inwardly or outwardly
The sash being divided into smaller or larger panes
Whether triple-glazing or double-glazing is used
Proper installation quality
Type of glass tint used
Presence of argon gas between panes

The correct answer is: Proper installation quality

Proper installation quality significantly influences a window's overall energy efficiency. Even if a window has an excellent efficiency rating, poor installation can lead to air leaks, drafts, and thermal bridging, which can compromise the window's performance. Properly installed windows create a tight seal against air and moisture, enhancing their ability to maintain indoor temperature and reduce energy consumption. Other factors, such as the type of glazing or gas filling, may contribute to energy efficiency but are not as critical as the installation. If a window is not installed correctly, even the best glazing or insulation won't prevent energy loss. Therefore, ensuring a high standard of installation is essential for realizing the full benefits of a window's energy-efficient features.
