Elbow Certifications

State Certifications

While some municipalities are working through the process of adopting relevant code, they often accept engineering reports clarifying the improvement in airflow efficiency to allow an exception when non-specific elbow penalties are in place. Often, the general engineering report will suffice. For convenience, you may also find a few state specific reports. You may also count on us for case by case support by contacting Frank Ambrose.
