Technical Guide Examines GPX Firerated Framings Safety and Aesthetic Balance

The GPX Architectural Series departs from conventional aluminum framing in one key respect: it is engineered specifically for fire-rated assemblies. Its appearance is intended to match the clean lines of standard aluminum frames, allowing designers to maintain a consistent sightline across commercial interiors while meeting fire-safety requirements.

In tested configurations, the system is designed to provide 60 to 120 minutes of fire protection and to resist the passage of flame, smoke and radiant heat. Those functions are intended to create time for evacuation and property protection. The system supports optional ballistic and blast customization for projects with additional security requirements, according to the specifications.

The framing system is described as meeting ASTM E119, UL 263 and ULC S101, internationally recognized fire-test standards. Its primary function is to limit the spread of fire, smoke and thermal radiation through an assembly while maintaining the visual character of a non-fire-rated frame.

Optional ballistic and blast configurations are available for specialized applications, while the base system remains focused on fire containment and transparency.

The system is available in a range of finishes to suit different architectural aesthetics. These include standard high-performance PPG paint coatings, clear anodized, bronze anodized, black anodized and Decoral finishes. For projects seeking natural textures, wood veneer options can be integrated, and decorative metal elements can be incorporated while maintaining the fire-rated assembly.

Installation applications include fixed walls, openings and single- or double-leaf doors. Maximum dimensions depend on the fire rating selected and the performance of the accompanying glass, so project teams must verify the system’s suitability against the fire-compartment requirements and glass specifications for each application.
