Understanding US WDMA


The Window and Door Manufacturers Association (WDMA) is a United States trade association that represents the interests of manufacturers of windows, skylights, doors, and related building products. The association has been in existence since 1927, and has grown to become a respected voice in the industry. In this blog post, we will discuss the US WDMA and its significance in the window and door manufacturing industry.

Standards and Certifications

One of the most significant roles of the US WDMA is the establishment of standards and certifications for window and door products. The association has developed various performance standards that manufacturers must adhere to in order to ensure the safety and reliability of their products. The WDMA Hallmark Certification Program is a third-party certification that verifies that a manufacturer’s products meet these standards. This certification is an important tool for architects, builders, and consumers who want to ensure that the products they are purchasing meet rigorous industry standards.

Advocacy and Education

Another critical role of the US WDMA is advocacy and education. The association advocates for policies and legislation that promote the interests of the industry and its members. This includes issues such as building codes, energy efficiency, and environmental regulations. In addition, the US WDMA provides resources and educational opportunities for its members, including webinars, conferences, and training programs. This helps ensure that members stay up-to-date on the latest industry trends and best practices.

Industry Collaboration

Finally, the US WDMA is a key player in promoting collaboration within the industry. The association provides a forum for members to share ideas and best practices, and to work together to address common challenges. This collaboration helps ensure that the industry as a whole is able to advance and innovate, and that individual companies are able to stay competitive.


In conclusion, the US WDMA plays a critical role in the window and door manufacturing industry. From establishing standards and certifications, to advocating for industry interests, to promoting collaboration and education, the association is a vital resource for manufacturers, builders, architects, and consumers alike. By ensuring that products are safe, reliable, and energy efficient, and by promoting innovation and best practices in the industry, the US WDMA helps to create a stronger, more sustainable future for the industry and the communities it serves.
