Kevin writes from Great Bend, Kansas: "We just purchased a house and I have a couple insulation questions. 1) The housing inspector indicated I should add more insulation to my attic (crawlspace), he said at least another 9 inches minimum. What type should I use, batts or blown? Batts I should be able to do myself, right, just roll it out over the existing insulation? What R-Value and how much would you recommend? 2) There is a Sunroom that still has exposed beams that I plan on installing insulation and then drywall and paint. I am going to have a Hot Tub in the Sunroom as well. What type or insulation would you recommend and how much? Would I need anything extra (vapor barrier) since I will have a hot tub in there?"

Answer: Owens Corning manufactures 9-1/2" FIBERGLAS® insulation rated at R-30. If you are planning to add to the existing insulation, we recommend unfaced insulation. The company also manufactures loosefill FIBERGLAS insulation. Use of this product requires a special machine and may call for professional installer.

If you are planning to condition your sunroom we recommend insulating all exterior walls and the ceiling with FIBERGLAS batts. In your climate we recommend the use of a vapor retarder facing down toward the sunroom.
