What is a window seal?

A window seal, also known as a window sill, is the horizontal ledge at the bottom of a window frame. It is typically made of wood, stone, or metal and serves several purposes:

1. Protection: The window seal helps to protect the window frame and interior walls from water damage by preventing moisture from seeping into the window frame.

2. Insulation: A well-sealed window sill can help to improve the energy efficiency of a home by preventing cold air from entering and warm air from escaping.

3. Aesthetics: Window seals can also add decorative elements to a window, providing a finishing touch to the overall look of the room.

Overall, maintaining a window seal in good condition is important for the functionality, appearance, and energy efficiency of windows in a home.
