Do it’s important to insulate steel ductwork?

Ducts are typically product of skinny materials, often sheet steel or fiberglass, which is why it’s so straightforward for the air touring by means of them to be misplaced.

The rationale for that is that builders don’t often insulate the ground of the empty area above an connected storage. In truth, they might not even insulate “knee partitions”.
