Supply and return ducts installed in an unconditioned attic are typically required to be insulated and sealed MAINLY to:
a.Reduce noise only
b.Support the ductwork
c.Match the color of the attic
d.Limit conductive heat loss/gain and air leakage so the system meets efficiency requirements
Explanation
Ducts in unconditioned space lose or gain heat and leak air, wasting energy; insulating and sealing them limits conductive losses and leakage so the system performs efficiently as required by the Energy Code. Noise, support, and color are not the primary reasons.
