What Is a Window Header? A header is any strong beam that horizontally spans an opening, such as a doorway. So, a window header is one that spans the top of a window opening. The header is the structural element—much like a bridge—that allows the space below to be open, not closed.
Why do you need a header above a window?
Headers take the weight of the materials and occupants above and transfer it via the trimmers down to the floors and foundations below. Longer openings require larger headers. Bearing walls (those that carry the weight of joists and trusses) require larger headers than nonbearing walls.
What size is a window header?
If you are creating an opening no wider than 4 feet, for a door or smaller window, then you need a 2-by-6 header. If you are putting in an opening between 4 and 5 feet wide, then you’ll need two 2-by-8 headers. If the opening will be 5 to 6 feet wide, such as for double doors, then you will need two 2-by-10 headers.
