As this is the underside of the roofing that we're talking about, any condensation wouldn't run into a gutter; it would just trickle down until it hits something which it would moisten or pool on. The anticon blanket is up against the metal, so the air that's carrying all that moisture is instead against the underside of the blanket. Temp difference between that air & the anticon blanket won't be as large as the temp difference between the air & the metal (which is closer to the temp of the outside air), so less moisture condenses on the underside of the blanket than would condence on the underside of the metal without the blanket. Roughly speaking, at least. Building Standards; Getting It Right! Hi all I’m in VIC and had some storm damage in my garage a month ago. Gutter found not fit for purpose.
