As mentioned in the previous post, the attic of my house had virtually no insulation in it. Indianapolis is sort of in a weird place when it comes to weather. We don’t often get heavy snowfalls or bitter cold in the winter, however, they do happen every so often. Since heat rises, an uninsulated attic lets out a lot of heat. Adding insulation is like putting a thick quilt over the top of the house, trapping most of the heat underneath it, which is what you want in winter. By trapping the heat, the heating bills should be lower. So the theory goes, at least.
In fall of 2016, I started looking at insulation, hoping to install it before winter. My first choice was to get insulation made from recycled denim, but it isn’t carried by stores in my area and getting it shipped to my house would have been prohibitively expensive. Fiberglass insulation is also expensive, but it’s available almost everywhere. Reluctantly, I decided to go with fiberglass because it’s cheaper and more commonly available. The final product I chose was Owens-Corning kraft-faced R-38 batts. Each floor of the house is a little over 800 sq ft, so I planned on getting that much insulation. Since each pallet of insulation covers approximately 320 sq ft, I bought two pallets and planned on seeing how much I needed after going through it all.
