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.
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 and specifiers as well as users, have reached a consensus.”
I.S.1A was revised and revamped several years ago to shift the specification to performance-based requirements as opposed to prescriptive criteria, making it more applicable in real-world construction. The standard established Performance Duty Levels that assist the user in finding and installing the right door, based on their conditions of use. Other selected highlights of the standard: the addition of Low Pressure Decorative Laminate as a face material; an updated section on the advantages of Factory Finishing versus Field Finishing; an explanation of Positive
Pressure fire doors and how to differentiate them from neutral pressure doors; and an updated face veneer chart, published in collaboration with the Hardwood Plywood and Veneer Association, Reston , Va. Copies of the standard are available at www.wdma.com or phone 847-299-5200 .
