Standard Thermal Break Aluminum Casement Window

Practical Thermal Performance for Residential and Light Commercial Projects

This outward-opening thermal break aluminum casement window combines a solid 1.8mm aluminum structure, outward-opening ventilation, Low-E insulated glass, and German G-U hardware in one project-ready system.

It is designed for custom homes, apartments, townhouses, villas, and light commercial buildings where reliable operation, flexible sizing, and balanced project cost matter.

Why Builders Choose This Aluminum Casement Window

The system focuses on the details that affect operation, installation, energy performance, and long-term project reliability.

Full Outward-Opening Ventilation

The side-hinged sash opens toward the exterior, providing a wide ventilation area without taking up interior space.

Balanced Thermal Break Design

A 67mm frame and 24mm thermal break strip reduce direct heat transfer while keeping the system practical for volume projects.

Double or Triple Glazing

Low-E argon-filled double glazing is standard, while triple glazing is available for projects needing greater glass capacity.

German G-U Hardware

German G-U hardware supports smooth sash movement and dependable locking. HK Kinlong hardware is also available.

Standard and Larger Sash Options

Different sash and hardware configurations support both conventional openings and larger project windows after engineering review.

Weather-Ready Sealing

Multi-level sealing supports low air leakage, water resistance, and stable operation in changing wind and weather conditions.

Flexible Window Configurations

Available as a single casement, casement with fixed glass, fixed window, or 90° and 135° corner combinations.

Project-Friendly Installation

Nail fin and mounting tab options help the window integrate with different wall structures and contractor installation methods.

Configured Around Your Drawings, Not a Fixed Catalog Size

Send a window schedule, BOQ, rough opening sizes, or architectural drawings for configuration review before production.

Glass, Hardware and Design Options

Insulated glass: 5mm Low-E + 15mm argon + 5mm tempered clear glass.
Triple glazing: 5mm Low-E + 12mm argon + 5mm + 12mm argon + 5mm.
Glass capacity: insulated glass units up to 39mm.
Project sizing: standard sashes from 450–700mm wide and 500–1500mm high; larger engineered options up to 1000mm wide and 2500mm high, subject to hardware and engineering review.
Hardware: German G-U or HK Kinlong in black or white.
Screen option: pleated retractable accordion insect screen.
Window layouts: single opening, opening with fixed panel, fixed window, and corner combinations.

Performance That Supports Real Projects

Reference U-Factor: 0.35 BTU/(h·ft²·°F), subject to the final glass configuration and applicable test report.
Low air leakage: reference value of 0.05 L/s·m².
Water resistance: reference water penetration resistance of 220Pa.
Wind pressure: reference resistance up to 2160Pa for properly engineered units.
Sound control: reference acoustic performance of approximately 35dB.
Energy-conscious glazing: Low-E coatings and argon-filled IGUs help reduce unwanted heat transfer.

Performance values are engineering references. Final results depend on size, glass package, opening configuration, installation, and the applicable project test report.

Which Thermal Break Casement Window Fits Your Project?

Both systems use 1.8mm aluminum profiles and outward-opening operation. The main difference is insulation and glass capacity.
