Energy Efficient Casement Window
Aluminum Awning Window
Triple Casement Window
TACW70 is a very popular thermal break aluminum casement window system, widely used in many countries. Whatever you need better thermal isolation, or better sound insulation, the system can supply a good solution.
The TACW70 is a very popular thermal break aluminum casement window system, built on a 70mm frame structure and engineered to solve the two challenges that matter most in modern facades: heat loss and external noise. A polyamide thermal barrier separates the inner and outer aluminum profiles, eliminating the thermal bridge that a monolithic aluminum frame would create, while the robust extrusion provides the slimmer sightlines and larger glazed areas that architects favour. Whether the priority is better thermal isolation or better sound insulation, TACW70 supplies a dependable solution, and it is widely used in residential homes, offices, commercial buildings and energy-efficient construction across many countries.
A polyamide strip separates the internal and external aluminum profiles, breaking the thermal bridge through the frame and dramatically improving insulation compared with a standard aluminum window. This reduces heating and cooling demand and raises interior surface temperatures.
Combined with Low-E double or triple glazing, argon fill and warm-edge spacers where specified, the thermal break allows the system to meet demanding energy codes without resorting to oversized profiles.
The combination of a strong, stable frame, thermal break geometry and high-performance glazing creates an effective acoustic barrier, making TACW70 a sound choice for buildings near roads, railways or commercial activity.
Aluminum permits narrow, elegant sections, so the frame occupies less of the opening and more of the elevation can be given over to glass — increasing daylight and expanding views.
Aluminum offers excellent structural integrity and does not rot, warp or crack. The extrusion maintains its rigidity across temperature extremes, providing a long, stable service life in a wide range of climates.
Aluminum naturally resists corrosion, and the powder-coated or fluorocarbon-coated surface further protects the profile, making the system suitable for humid and coastal-adjacent environments.
The factory-applied finish resists fading, scratching and chalking, minimizing the need for repainting or other surface treatments beyond routine cleaning.
Fixed, tilt-turn, awning and swing in/out configurations are all available, and the profiles can be formed into a wide variety of window shapes and styles to suit the architectural intent.

We provide comprehensive OEM/ODM services to meet specific project requirements:
Precision Manufacturing: Advanced CNC cutting, thermal break strip assembly (crimped or roll-formed) and corner assembly for seamless, accurately squared joints.
Surface Treatment: Professional powder coating in any RAL color, plus fluorocarbon coating for high-end and high-exposure applications and wood grain finishes.
Glass Build-Up: Double and triple glazed units with Low-E coatings, argon fill, warm-edge spacers, laminated or tempered panes and built-in blinds where specified.
Hardware Selection: Multi-point locking, tilt-turn gear, handles and hinges from domestic or international brands to match the project specification.
Configuration: Fixed lights, transoms, mullions, awning and tilt-turn combinations, plus round arcs and special shapes.
Opening Inspection: Ensure the opening is level, square and clear of debris before installation, and confirm the structural fixing points.
Foam Filling: Use high-quality expanding foam to fill the perimeter gap for optimal insulation and waterproofing, then trim flush after curing.
Secure Anchoring: Use specialized expansion bolts with standard spacing for structural stability; avoid fixing through the thermal break strip.
Calibration: Use levels and plumb lines to confirm the frame is perfectly vertical and horizontal before final tightening.
Waterproof Sealing: Apply external grade silicone sealant to the exterior joints and ensure drainage holes and pressure-equalization slots are clear.
Glass Alignment: Use correct setting blocks to prevent direct contact between glass and aluminum, and ensure the glazing gasket is correctly seated.
Hardware Adjustment: Fine-tune hinges and lock points after installation so the sash closes evenly and the gasket compresses uniformly.
Film Removal: Remove protective films promptly after installation to avoid adhesive residue from sun exposure.
Regular Cleaning: Clean frames and tracks with a soft cloth and water; lubricate hardware annually. Avoid abrasive cleaners that could damage the coating.
Avoid Impact: Protect glass and corners from heavy mechanical impact during construction.
Can the size be customized?
Yes. All TACW70 windows are custom-made to fit your specific rough openings.
What does thermal break mean?
A polyamide strip separates the inner and outer aluminum profiles, preventing heat from conducting directly through the frame — improving insulation and reducing condensation.
Is TACW70 suitable for coastal areas?
Yes. Aluminum resists corrosion naturally, and the powder or fluorocarbon coating provides additional protection in humid and salt-laden environments.
How many cycles should the hardware last?
Our hardware is cycle-tested to 50,000+ open/close cycles under normal operating conditions.
How long is the warranty?
We typically offer 5–10 years warranty on profiles and hardware, depending on the project requirements.
Do you provide export packaging?
Yes. We use protective corners, stretch wrap, and seaworthy wooden crates or pallets to ensure safe delivery.
