The duct insulation I want to have installed is in 5ft. by 25ft. rolls. It has a reinforced foil face and is a 2" cotton based product.
I had a tech comment that it would be very difficult to install. Am i missing something here, why would it be any more difficult than fiberglass?
Would you not just measure the circumfrance of the metal duct, cut it with a slight overlap on the foil facing and duct tape? Is duct tape good enough for this purpose or should I be requesting some other kind of product at the seams?
Any insight would be great.
