Window & Door Manufacturers Association

What Window & Door Manufacturers Association does

The Window & Door Manufacturers Association (WDMA), founded in 1927 and headquartered at 2001 K Street NW, Washington, D.C., is a U.S. non-profit trade association representing manufacturers of windows, doors, and skylights and their component/material suppliers. The association's core product portfolio is anchored in industry standards — ANSI/WDMA I.S.1A-21 (Architectural Wood Flush Doors), ANSI/WDMA I.S.6A-21 (Architectural Stile and Rail Doors), WDMA I.S.12A (exterior fenestration products) — and the ANSI-accredited Hallmark Certification, an impartial third-party product verification program, with energy-performance ratings delivered in partnership with the National Fenestration Rating Council (NFRC) and green building alignment via LEED and the National Green Building Standard (NGBS). WDMA supplements standards and certification with technical resources (Code Resource Center, Technical Interpretations & Bulletins, The Learning Center, Glossaries), advocacy through its OneVoice program and National Policy Agenda, a state-level issue tracker, and a recurring events portfolio that in 2026 was rebranded to comprise the FRAME Conference (Minneapolis, June 2026), Advocacy Summit (Washington, DC, March 2026), Executive Leadership Forum (Boston, October 2026), monthly Town Halls, and the annual Committee Week, alongside an Open Up To Performance educational platform for builders, architects, and remodelers.

Revenue mechanics are diversified across four streams: recurring membership dues from manufacturers and suppliers, recurring Hallmark Certification fees, event registrations and sponsorships (FRAME, Advocacy Summit, Executive Leadership Forum), and one-time sales of standards documents and technical publications through the WDMA Store. Pricing is not publicly disclosed and is quote-based across member tiers. The GTM motion is community-led: WDMA acquires and retains members through advocacy value (federal and state regulatory influence), the certification program's market signaling, technical standards authority, and event-driven networking, supported by content channels (openuptoperformance.com, Beyond The Frame newsletter, Facebook/Twitter/LinkedIn, webinars). Customer segments span a vertical core of window, door, and skylight manufacturers plus suppliers, and a horizontal extension into builders, architects, and remodelers. WDMA executes this with a lean 1-10 employee staff and convenes the broader U.S. fenestration value chain against a 2023 market of 64.8 million window and door units shipped and 1.42 million housing starts.

Expansion highlights5 records

Others

• International Code Council (ICC): Building code developer with which WDMA participates in code development via the Exterior Products Codes Committee. ICC sets the regulatory framework that WDMA's standards and certification align to.
• National Fire Protection Association (NFPA): Publisher of fire and life safety codes (NFPA 80, 101, 105) that affect door and window standards. WDMA provides member resources aligned to NFPA codes.
• ASHRAE: Standards body whose 90.1 energy standard influences fenestration requirements. WDMA holds an organizational seat on ASHRAE 90.1, making it a key regulatory counterpart.
• American National Standards Institute (ANSI): Accreditation body for WDMA's Hallmark Certification and co-developed standards. ANSI is not a direct competitor but enables WDMA's regulatory credibility.
• Home Innovation Research Labs: Third-party verification body for the National Green Building Standard that WDMA partners with. Comparable as a certification/testing partner rather than a direct competitor.

Direct peers

• National Fenestration Rating Council (NFRC): Partner and partial peer providing energy performance certification for windows, doors, and skylights. NFRC ratings are integrated into WDMA's Hallmark Certification program, making it a directly comparable certification body.
• American Architectural Manufacturers Association (AAMA): Closest direct peer as AAMA co-sponsors the NAFS standard with WDMA and jointly issues Technical Interpretations. Both serve fenestration manufacturers with overlapping standards development and certification activities.

Broad incumbents

• National Association of Home Builders (NAHB): Larger industry association representing residential construction. NAHB addresses the downstream demand side of fenestration products while WDMA represents the supply side, making them complementary but loosely comparable.

Regional players

• Fenestration Canada / Fenestration Manufacturers Association: Canadian fenestration industry association analogous to WDMA. Operates in the same product category with comparable standards and certification offerings but focuses on the Canadian market.

Emerging players

• Insulating Glass Manufacturers Alliance (IGMA): Trade association focused on insulating glass units, which are key components in fenestration products. IGMA overlaps with WDMA's standards development mission but targets a narrower product segment.
