Paula writes from Dallas, Texas: "How much blown fiberglass insulation is needed to insulate 1850 sq. feet. Do you know of any reasonably priced contractors?"

Answer: Because specific insulation products vary by region, you will need to visit an insulation distributor, or call one, to find out which type of blown insulation is available in your area. Each type of blown insulation will have a conversion chart that provides that information you want. There is also a Data Sheet for each product that will have the coverage information.

To find a contractor, I recommend visiting the Owens Corning website. On the page for Certified Energy Professional® Contractors there is a link that will find a CEP contractor in your area. A Certified Energy Professional can recommend and install the proper levels of PINK fiber glass insulation for each application, make suggestions for upgrading, and can insulate homes for sound control. CEPs are trained in proper installation techniques and are knowledgeable of current building codes. All carry workers compensation and liability insurance but Owens Corning does not guarantee workmanship.
