Cutting-Edge Design: ES-1 & GT-1 Compliance
Understanding wind uplift, code requirements, and perimeter edge metal specification to protect the building envelope

Perimeter edge metal systems are the building envelope’s first line of defense against wind and severe weather. The International Building Code requires the ANSI/SPRI/FM 4435/ES-1 (ES-1) and ANSI/SPRI GT-1 (GT-1) testing standards for edge metal and gutter systems that secure low-slope roof membranes.
This course examines how wind uplift challenges fascia, coping, and gutter systems and how ES-1 or GT-1 testing demonstrates resistance to wind loads. Attendees will learn how code requirements, wind design pressures, and tested system performance inform specification decisions that help protect the roof, the building, and the people inside.

LEARNING OBJECTIVES
- Describe how severe weather and wind uplift dynamics affect perimeter edge metal systems and the security of the building envelope.
- Identify how the ANSI/SPRI/FM 4435/ES-1 (ES-1) and ANSI/SPRI GT-1 (GT-1) testing standards are incorporated into the International Building Code.
- Explain how to calculate wind design pressures and how they relate to the ES-1 and GT-1 test methods to inform product selection.
- Discuss the importance of verifying compliance and specifying systems tested to ES-1 or GT-1 to support roof performance, building integrity, and occupant safety.
