Framing & StructuralCâu 306 / 700
In a framed wall opening, what is the PRIMARY structural role of the header?
a.To provide a nailing surface for drywall only
b.To seal the opening against air leakage
c.To carry loads from above across the opening to the studs on each side
d.To hold the window frame square
Giải thích
A header is a beam that spans the opening and transfers the roof, ceiling, or floor loads above it down to the jack (trimmer) studs on each side and into the foundation. Drywall nailing, air sealing, and squaring the window are secondary or unrelated functions.
