    Materials and Resources Credit 4: Recycled Content

    Cornell product components contain Post Industrial and Post Consumer recycled content as listed below. Please note that Product Type and Product Size determine final Recycled Content calculation results. Precise Recycled Content information can be provided when dimensioned products are identified, excluding TranZform®, Side Folding Grille Products and Extreme® Performance Rubber Doors. The precise post industrial and preconsumer values are calculated by internal programming systems based on the build sheets for each door.
