Window System

‍Dual Inward-Opening Glass and Screen Sashes

The glazed sash and insect-screen sash open independently toward the interior, providing flexible ventilation and convenient access for cleaning and maintenance.

‍

Flexible Tilt-and-Turn Ventilation

Open the glazed sash fully for maximum airflow, or tilt it inward for secure, controlled ventilation without fully opening the window.

‍

Triple-Glazed Thermal Construction

A 97 mm thermally broken frame, 35.3 mm PA66 GF25 thermal barrier and triple-glazed insulated glass work together to support year-round indoor comfort.

‍

Flush Architectural Detailing

Flush frame-and-sash detailing, outward-positioned glazing and refined visible profiles create a cleaner appearance while preserving daylight and exterior views.

‍

Durable Hardware and Weather Protection

Multi-point hardware, multi-layer EPDM sealing and concealed drainage support smooth operation, security and dependable resistance to air and water over time.

Comfort
Triple glazing, thermal separation and multi-layer sealing help support a quieter, more stable indoor environment throughout the year.
Ventilation
Full inward opening, tilt ventilation and an independently operated screen sash provide greater control over airflow and everyday use.
Integration
Flush detailing, concealed drainage and refined frame proportions help the window integrate cleanly with interiors and exterior elevations.
