Which type of header is required for a span greater than 6 feet?

For spans greater than 6 feet, a double header with supports is the appropriate choice due to its structural integrity and load-bearing capacity. Headers are critical components in framing, particularly above openings like doors and windows, as they transfer loads from the structure above down to the framing below.

When a span exceeds 6 feet, the load demand increases significantly. A single header may not provide sufficient support to safely carry the weight of the roof or upper floors, potentially leading to sagging or failure over time. A double header, which consists of two pieces of lumber stacked together, effectively distributes this load over a wider area and enhances the overall strength of the structure when paired with adequate supports. This configuration is essential in ensuring compliance with building codes and maintaining safety standards.

The absence of specific requirements for headers in some situations does not apply when spans exceed 6 feet. Similarly, while a standard header may suffice for shorter spans, it does not meet the requirements for greater distances. Therefore, a double header with supports is mandated to ensure that safety and structural stability are maintained in residential buildings.
