What is a header in construction?

In construction, a header refers to a horizontally placed framing member that is typically used to support the weight above openings such as doors, windows, or other structural elements. Its primary purpose is to distribute the load from the structure above the opening across the framing members on either side, ensuring the integrity and stability of the wall.

Headers are essential for maintaining the overall stability of a building, as they help manage vertical loads and transfer them to the surrounding framing. This distribution of weight prevents excessive stress on the surrounding materials and helps avoid structural failure.

The other options do not accurately describe a header, as a vertical member would refer to posts or studs, while a diagonally placed strut is generally associated with bracing for added support. Additionally, roofing material does not pertain to the structural framing elements that headers represent. Understanding the role of headers can greatly enhance one's comprehension of foundational framing techniques in construction.
