Framing & StructuralCâu 304 / 700
Beyond structure, why is careful sealing of subfloor and sheathing joints emphasized in current California construction?
a.It increases the panel span rating
b.It limits air leakage, supporting the Energy Code's building-envelope tightness goals
c.It replaces the need for wall insulation
d.It allows nails to be spaced farther apart
Giải thích
Sealed sheathing joints reduce uncontrolled air leakage through the envelope, supporting the Energy Code's air-tightness objectives and comfort/efficiency. Sealing does not change span ratings, replace insulation, or permit wider nail spacing, which is set by the structural fastening schedule.
