The Window and Door Manufacturers Association (WDMA) National Architectural Door Council (NADC) has initiated a project to create ISO-compliant Product Category Rules (PCR) for architectural wood flush and stile and rail doors (CSI Master Codes 08 04 00). Creation of a PCR is the first step, so door manufacturers can develop ISO-compliant Life Cycle Assessments (LCA) and Environmental Product Declarations (EPD) for documenting their products’ environmental attributes, for use by architects and specifiers in obtaining LEED v4 credits.

“This is an important activity for WDMA,” said Robert Stuart, vice president of engineering at TruStile and the new Chair of the WDMA National Architectural Door Council. “Having this fundamental document will keep architectural wood door manufacturers on pace with the sustainable product needs of architects and specifiers. WDMA is positioned to be the front-runner on architectural wood door environmental issues.”

WDMA has selected the American Society for Testing and Materials (ASTM) as the Program Operator to facilitate creation of the architectural wood door PCR. The PCR will be developed through a Technical Advisory Committee (TAG), consisting of WDMA members and other interested individuals. The process is expected to take between six and eight months to complete. For more information, contact Jeff Lowinski at
