What is the function of a header in framing?

The function of a header in framing is to support weight above openings like doors and windows. Headers are structural members that are placed horizontally across the top of these openings to transfer the load from the roof or the structure above to the studs on either side of the opening. This ensures that the wall maintains its integrity and strength while allowing for passageways or light through the openings. The design and material of headers are crucial for ensuring proper load distribution, making them an essential component in framing techniques. Used correctly, they help prevent sagging or structural failure around these crucial areas.
