"H" writes from Dallas, Texas: "How many bags of the pink blowing stuff is needed to cover 1850 sq feet? How big are the bags and how much do they cover? Why is this information not available on your web site like other manufacturers? The number of bags is important because this is how consumers get ripped off - density."

Answer: The information is available on the Owens Corning website in the product data sheets. You can access the product data sheets by clicking on the button at the top of the home page marked Literature. You need to know what R Value you want to install and then go to the chart of the selected blowing insulation to find the coverage needed. The information is also listed on every individual bag.

When you click on the Literature button and the Document Library search form appears, type "loosefill insulation" in the Topic or Keyword window, and make sure the Business Unit window reads Building Materials. If it does not, open the drop-down list and select Building Materials. When you click on Submit, you will see a list of available documents including brochures, certificates, data sheets, installation instructions, Material Safety Data Sheets (MSDS), etc.
