What is one way to reduce airflow between the window and frame?

Improving sealing techniques is a key method for reducing airflow between the window and frame. Proper sealing can prevent air leaks, which are common in poorly sealed windows. Gaps and cracks around the window frame allow outside air to enter the home, reducing energy efficiency and comfort. By applying weather stripping, caulk, or other sealing materials, the connection between the window and frame becomes tighter, effectively minimizing airflow and enhancing insulation performance.

While increasing frame size, upgrading to triple-pane windows, or changing the window material might impact energy efficiency or thermal performance, they do not specifically address the critical factor of reducing airflow directly at the interface between the window and the frame. Sealing techniques specifically target air leaks at this junction, making them the most direct and effective approach for this issue.
