LESLIE: Joanne in Illinois wants to talk insulation. How can we help?
JOANNE: I have purchased this brick home and it’s a two-story home. And up in the attic is some insulation. Now, I think it’s very old insulation. They said the name of it and I do not know what kind it is but I was just wondering would it better to have some insulation blown in or just to put those rolls like …
LESLIE: The batting?
TOM: Well, if the insulation that’s in your attic right now is compressed …
JOANNE: No, it’s kind of like rolled (ph).
TOM: Mineral wool?
JOANNE: Could be.
TOM: If it’s mineral wool, it’s really super thin.
TOM: And – or rock wool is another type. It’s really super thin stuff. And you probably – in a best case scenario I would tell you to take it out except that I happen to know that rock wool insulation sometimes contains asbestos. And as a result, you don’t want to disturb it. So …
LESLIE: Is it safe to apply just a pink rolled batting on top of it?
TOM: You could put an unfaced insulation over it. And typically, with the age of your house, you’re going to want to put two layers of insulation. So you’re going to want to fill up that ceiling joist with unfaced insulation at the top, then you’re going to want to put a second layer perpendicular to that.
LESLIE: Covering the joist.
TOM: And that’s going to be a very cost effective home improvement project that will really impact your heating costs.
JOANNE: Mm-hmm. Bye. I enjoy your program. Thank you.
LESLIE: Thanks, Joanne.
TOM: Thanks so much for calling us at 888-MONEY-PIT.
