DES PLAINES, IL -- The American National Standards Institute (ANSI) granted approval to the recently revised Window and Door Manufacturers Association (WDMA) standard I.S.1A-04 Industry Standard for Architectural Wood Flush Doors. WDMA holds and maintains ANSI-approved standards for both architectural wood flush doors (I.S.1A) and architectural stile-and-rail doors (I.S.6A-01, Industry Standard for Architectural Stile and Rail Door.) There can only be one ANSI-approved standard in a specific area.


“Approvals such as this continue to showcase the credibility and influence of WDMA as a recognized standards authority,” said Joel R. Hoiland, CAE and president, WDMA. “This is quite a significant accomplishment for our organization, as specifiers look for ANSI approval in the product selection process. ANSI approval is achieved through an exhaustive ballot process, and is granted only after individuals in the industry, including designers, architects, specifiers and users, have reached a consensus.” Copies of the standard are available at or phone (847) 299-5200.
