Framing & StructuralCâu 310 / 700
A framer builds exterior corners using a three-stud arrangement that leaves room for insulation and provides drywall backing. What is the MAIN advantage of this over a solid stud-packed corner?
a.It uses more lumber
b.It eliminates the need for corner sheathing
c.It makes the corner load-bearing where a solid corner is not
d.It allows insulation into the corner cavity, reducing thermal bridging, while still backing the interior finish
Giải thích
An insulated (California/three-stud) corner leaves a cavity that can be insulated, cutting the thermal bridge a solid lumber-packed corner creates, and still provides a nailing surface for interior drywall. It uses less lumber, does not remove sheathing, and both corner types can be load-bearing.
