Question: How should I insulate the ceiling of a basement that will be heated?
Pat writes from Kenosha, Wisconsin: "I have a cabin in Wisconsin that I close up over the winter. I heat the basement during the winter but not the rest of the cabin. I'm thinking of insulating the basement ceiling, how should I do this? Also the basement walls are insulated on both sides."
Answer: We recommend Kraft-faced R-19 or Kraft-faced R-25 fiberglass insulation with the paper facing the heated area. The paper facing then needs to be covered with a 15-minute thermal barrier like half-inch gypsum wall board.
