Question: What insulation should I use for a garage ceiling?
Andrew writes from Baltimore, Maryland: "My kitchen is above my unheated garage. It can get quite cold in my kitchen. The ceiling in the garage is concrete. I only need to insulate the garage ceiling. Which insulation/R-value should I use?"
Answer: We recommend Kraft-faced FIBERGLAS™ R-19 or R-25 for the garage ceiling. The vapor retarder (Kraft paper) should be installed to the warm-in-winter side (or up toward the kitchen).
