Any thoughts / experience with insulating material for a 4 inch
diamter tubing used in a bathroom exhaust fan installation? The
tubing shall be in an attic crawl space in a ranch style house located
on Long Island, NY (typical low and high temperatrures: 0F and 100F
degrees).

I am wondering if pipe insulation or batt fiberglass insualtion should
be used in this application ?

Is Owens-Corning Fiberglass Duct Wrap

appropriate material for this application ?

In most situations you should not have a problem with it, just be sure
vent it to the outside not to the inside of the attic.
