An Owens Corning preferred contractor is a local insulation pro who's been vetted for quality and training. They know the products inside out, from fiberglass batts to spray foam, and can help you get the right R-value for your attic or walls. It's a good shortcut if you want someone who'll do the job right the first time, without upselling you on stuff you don't need.
