Cores – The interior cavity of the fiberglass door is completely filled with a corrosion-resistant material. The type of core that is used, such as Polypropylene, Polyurethane Foam, Balsa or Mineral, is determined either by application or specification. Core materials that accommodate sound ratings, fire ratings, and higher R values which improve energy efficiency are all available at your request.
