Blown insulation is perfect for insulating irregularly shaped areas with numerous nooks and crannies, and Owens Corning is one of the most reputable insulation manufacturers in the nation. At D & W Windows and Sunrooms, we offer the new Owens Corning Propink L77 Pink Fiberglass Insulation. This particular attic insulation offers the highest coverage in the industry, with its High Performance Fiberizing Technology allowing the insulation to achieve and maintain industry-standard R-values with less material than is needed with other, similar products.

Outstanding Attic Insulation

  • Is formaldehyde free
  • Resists fungus and mold growth
  • Won’t settle, rot, or decay, so it will not lose its R-value
