Out of curiosity, with a poorly insulated attic, aside from the warm air below raising and escaping through the attic, does the cold air above act like a vaccum, succing the warm air out even quicker?
Now to my attic, we renovated the rear portion of our 1968 house in Boston and during the process I reinsulated the back portion with faced R-38 and am now in the process of running R-13 or R-19 perpedicular.
The front portion of the house/attic insulation is untouched. It is a double faced R-13 at best.
My questions are:
Can I keep the double face bats down and run unfaced R-19 over it, then R38 perpandicular OR should I remove the existing bats, place new faced R-38 with R-13 or R-19 perpedicular, thus not wasting anything allready up there?
Thanks -
