In framing a floor opening, what role does a header play?

The role of a header in framing a floor opening is to support the load above that opening. When an opening, such as for a door or window, is created in a wall, it disrupts the continuous vertical load-bearing structure. It is essential to transfer the weight of the materials and forces above down to the foundation properly. The header is critical in ensuring that this load is evenly distributed to the surrounding studs or framing members, preventing sagging or structural failure. This configuration maintains the integrity and stability of the wall and the structure as a whole, making the header a vital component in building construction where openings are involved.
