    Ultra violet light will cause the gray jacket to become brittle and fail. That's what this one looks like happened. Doesn't need mice, rats, or the HO storing boxes on top of the flex duct - it just turns to dust.

    Exactly! If sunlight (UV) gets to flex with grey vinyl bapor barrier it will crumble. I try to always use foil now.

    Here are the "after" pics. We ripped out all of the flex and replaced it with hard pipe. The 2nd floor Unico system is not yet complete. I will post those pics when finished. -DF
