Cold Exhaust Fan Ductwork

My fan duct radiates a very noticeable amount of cold air from the attic. Can I build a wood box around this to seal it off or does that violate some kind of code?

You can enclose it if you wish. I would get some rigid insulating foam or insulating blanket and wrap around it.

Wrap it in the attic, too (and make sure it is vented all the way to the outside and not blowing air into the attic.)
