When you are burying ducts in blown-in fiberglass, I hope They are really 1st insulated with duct insulation Geared up by using a vapor barrier. Or else, the ducts are going to be dripping wet throughout the summer months.
The barriers consist of a extremely reflective material that demonstrates radiant warmth instead of absorbing it. They don't, nonetheless, reduce warmth conduction like thermal insulation components.
As a result the temperature of the attic House (previously mentioned the insulation) should have Completely no bearing on the temperature In Radiante Barrier the creating and your heating expenses.
I'm setting up on applying a combination of one'' XPS and 1'' poly ISO within a rafter cavity which also function a air flow cavity. I was taking into consideration the ISO board be the most interior part of the stack on account of its low perm score.
