Why this matters

Not all vinyl profiles are equal — certification proves it

Any vinyl extrusion manufacturer can claim quality. AAMA certification requires proving it — through third-party laboratory testing on randomly sampled production profiles, a documented Quality Management System, and at least two unannounced in-plant inspections per year.

For window manufacturers, this has direct business implications:

✓
Required for Gold Label windows — AAMA-certified profiles are required for windows certified under the AAMA Gold Label program, which is increasingly specified by architects, builders, and code officials.
✓
Specifiable by code — some states and jurisdictions require AAMA-certified profiles for energy code compliance or product approval.
✓
Publicly verifiable — your customers, architects, or inspectors can look up our FWH-1 designation in the FGIA directory and confirm it independently.
✓
Ongoing compliance, not a one-time test — biannual inspections mean our certification reflects current production, not a snapshot from years ago.

Important: If a vinyl profile producer is not listed in the FGIA Certified Profile Licensees Directory, their extrusions may not be used in a window or sliding glass door which is labeled in the AAMA Gold Label Certification Program. Always verify before sourcing.

The process

What AAMA certification actually requires

Administered under AAMA 109 by the Fenestration & Glazing Industry Alliance (FGIA), the program is designed to ensure that certified profiles meet the performance requirements of AAMA/WDMA/CSA 101/I.S.2/A440 — the primary North American standard for window and door performance.

Third-Party Profile Testing

Randomly selected production samples are sent to an AAMA Accredited Laboratory — not a manufacturer-chosen lab — for testing against AAMA specifications. For every new profile added to the program, samples are selected and tested before certification is granted.

Quality Management System Review

The manufacturer must prepare and submit a Quality Control Manual outlining the procedures used to maintain ongoing compliance. This QMS is reviewed by the program Validator, Associated Laboratories, Inc. (ALI), before certification is granted — and audited during each subsequent inspection.

FGIA Authorization and Listing

After QMS review and test report approval, FGIA issues authorization and adds the licensee to the public Certified Profile Licensees Directory. Profiles may not be labeled as certified until this authorization is received.

Biannual Unannounced In-Plant Inspections

At least twice per year, FGIA inspectors conduct unannounced visits to verify that production continues to conform to program requirements. During these visits, profiles are resampled for continuation testing and the QMS is audited. This ongoing compliance requirement is what makes the certification meaningful over time.

Corrective Action Accountability

If any discrepancy is identified during an inspection, the licensee must respond within 30 days with a corrective action plan — including root cause analysis and preventive measures. The program has teeth: non-compliance results in removal from the directory.

Performance testing

What certified profiles must pass

AAMA certification testing covers five performance criteria derived from years of outdoor weathering data and laboratory research.

💥

Impact Resistance

Profiles must withstand impact loading — including low-temperature impact — without cracking, splitting, or deformation.

📐

Dimensional Stability

Wall thicknesses, profile geometry, and critical dimensions must remain within specification across production. This is what ensures your fabrication process is consistent.

🌡️

Heat Resistance

Profiles must resist distortion and degradation when exposed to elevated temperatures — important for profiles installed in sunny climates like Southern California.

⚖️

Weight Tolerance

Material weight per linear foot must fall within specified limits — confirming correct compound formulation and wall thickness across the production run.

☀️

Color Retention

Based on real-world outdoor weathering test results, profiles must demonstrate long-term color stability — no significant fading, chalking, or discoloration over time.

All Five Criteria

Weihui FWH-1 profiles pass all five criteria as confirmed by third-party laboratory testing and verified through ongoing in-plant inspections.
