ThinWall Aluminum Door System

Frameless. Pre-Glazed. Precision-Fit.

Designed for Finished Openings

The ThinWall system by Linea Motion is a precision-engineered commercial interior aluminum door system designed specifically for finished openings where a clean, frameless aesthetic is essential. Ideal for architects and designers specifying interior glass doors for modern office environments, healthcare facilities, educational buildings, and upscale retail spaces, the ThinWall system delivers the clean, minimal sightlines that define contemporary commercial interiors.

The ThinWall door frame integrates directly into finished walls or glass panels, eliminating the need for additional aluminum trim and dramatically reducing installation labor. This frameless approach creates an uninterrupted visual flow between spaces, maximizing natural light transmission and maintaining open sightlines throughout the interior.

Every ThinWall door arrives pre-glazed and ready to install, streamlining the construction timeline and eliminating the need for field glazing. With up to 3/4" of built-in adjustment, the system accommodates real-world construction tolerances while maintaining a precise, flush appearance. This built-in tolerance means fewer callbacks and a cleaner finished product.

The ThinWall system is available in six configurations sliding doors, swing doors, conference room doors, pivot doors, barn doors, and glass walls giving architects and designers the flexibility to specify the right solution for every opening in a project. All ThinWall products are manufactured in Omaha, Nebraska, and delivered as complete, ready-to-install assemblies.

Applications include modern offices and coworking spaces, glass partitions and room dividers, healthcare clinics and exam rooms, educational facilities, and any environment where clean sightlines and natural light are priorities. Compare with the Trimmed system for rough opening applications.
