To what is a builder referring when pointing to a structural beam supporting the load over a window in a residential structure?

1. Casing

2. Jamb

3. Lintel

4. Sash

5. Stile

6. Mullion

The correct answer is: Lintel

A builder referring to a structural beam that supports the load over a window in a residential structure is referencing a lintel. A lintel is a horizontal support that spans an opening, such as a window or door, to bear the load from above and redistribute it to the surrounding walls. This structural element is essential in ensuring the stability and integrity of the building, especially where there are openings in load-bearing walls. The other options involve different components of window construction. Casing refers to the framework around the window, jambs are the vertical sides of the window frame, sashes are the movable parts of a window that hold the glass, styles are the vertical pieces of a frame (for example, in a door or window), and mullions are the vertical strips dividing two or more windows. While each of these plays a role in the construction and appearance of a window, none of them serve the specific structural function that a lintel does.
