Three Independent Tracks for Wider, More Flexible Sliding Openings

This thermal break aluminum sliding window uses three parallel tracks, allowing three or six sashes to move in a layered horizontal configuration.

The system is suited to wide residential openings, apartments, villas, townhouses, and light commercial projects where more sliding panels and a larger opening area are required.

Why Use a Three-Track Aluminum Sliding Window?

The third track creates more panel movement and a wider usable opening without changing the familiar horizontal sliding operation.

Three Parallel Tracks

Three independent tracks allow multiple sashes to stack more efficiently and create a wider opening than a standard two-track window.

Three-Sash or Six-Sash Layouts

Choose a three-track three-sash configuration or a larger three-track six-sash window for broad wall openings.

Wide Sash Proportions

Each sash can be produced from 600–1500mm wide and 550–1800mm high, supporting generous glazing areas.

120kg Sash Capacity

The system supports up to 120kg per sash for larger Low-E insulated glass panels.

Thermal Break Construction

A 14.8mm thermal break strip separates the interior and exterior aluminum sections to reduce direct heat transfer.

Fixed Screen Options

Fixed stainless steel mesh or aluminum mesh can be added according to the project ventilation and insect-control requirements.

Designed for Wide Multi-Sash Window Openings

The three-track layout, sash count, screen, insulated glass, hardware, color, and installation method can be coordinated from the project drawings.
