    LESLIE: Glen in South Carolina has a question about insulation. What can we do for you today?

    GLEN: Hi, thanks for taking my call.
    I was wondering – I have the fiberglass blown insulation in my attic and I’m thinking about adding some more and I was thinking about adding cellulose-type insulation on top of that. Will that cause a problem with the value or anything like that?
    TOM: Well, you can add different types of insulation on top of each other but, frankly, I would recommend against it. If you have fiberglass insulation now I would add more fiberglass insulation on top of it and I would use unfaced fiberglass insulation and I would install it perpendicular to the existing insulation. That will give you good coverage and you’re going to be looking for about 19 inches of batt insulation totally, on average, to give you good insulating value.
    GLEN: OK. Well, I do appreciate your help.
    TOM: You’re welcome, Glen. You know, there’s a good homeowner’s guide to insulating online at a website called InsulateandSave.com. It’s put together by the experts at Owens Corning. You might want to take a look at that and it’ll walk you through some of those steps.
    GLEN: OK, I’ll look at in a little while.
    TOM: Thanks so much for calling us at 888-MONEY-PIT.
