Structural & Design Features

Concealed sub-frame

Concealed Sub-Frame

The system can be configured with a concealed sub-frame and flush-frame appearance on both interior and exterior elevations, providing a clean architectural appearance and reducing visible frame lines.

Insect screen sash

Insect Screen Sash

The insect screen sash is designed for inward operation and can be fitted with anti-collision corner guards for improved usability and protection during operation.

Corner and frame assembly

Corner & Frame Assembly

The frame, mullions, sub-frames, and sashes are assembled using injection-molded corner keys. Two-component structural corner adhesive is injected into the corner joints to improve joint integrity, dimensional stability, and water resistance.
