The aluminium windows 1800 x 1200 are aluminium casement windows with 1.4MM profile thickness, configured for commercial, residential, and exterior applications. Project buyers and specifiers evaluating outward-opening window systems can assess this product for buildings requiring controlled sash operation and slim-frame daylighting.
- Outward opening / awning operation with friction stay design that maintains sash position without additional support arms
- Slim frame design maximizes daylighting area and visual permeability while achieving optimized material efficiency
- Custom color options including PVDF coated finishes for exterior exposure, available for project orders meeting minimum quantity requirements
- Products meet NFRC, AS2047, and CE standards, with additional testing available upon request
Product Details
The aluminium casement window is constructed with a 1.4mm profile thickness and 50mm frame width, using an aluminium profile with double tempered glass units (5mm+20A+5mm) filled with argon gas and separated by a PVDF aluminium strip. A silicone glass bonding process forms a multi-layer sealing barrier, and EPDM weather seals are fitted around the sash perimeter. The sash opens outward or as an awning on 13-inch flat open friction hinges that maintain sash position without additional support arms. A customized fork-type handle connects directly to the transmission mechanism, where customized transmission boxes transfer handle rotation to integrated lock points around the sash with sequential engagement for consistent seal compression.
The system supports diversified glass configurations including single glass, triple glazing, laminated glass, and frosted glass, and custom shapes such as rectangular combinations, angled tops, and geometric forms are available. The WY-50 series standard stock color is a Black Skin finish, and fork-type handles are supplied with multiple finish options. DERCHI can supply the complete window system including profile, hardware, accessories, and glass as finished products ready for installation, and the system is compatible with external fly screens. Before finalizing selection, confirm the glass configuration, custom shape, finish color, handle finish option, and whether external fly screens are required.
Product Features
WY-50 Series casement window with 1.4mm profile thickness and 50mm frame width — these dimensions inform structural requirements and visible frame proportion in the opening.
Outward Opening / Awning configuration — the sash projects outward, affecting interior clearance and exterior space planning.
Water tightness at 650 Pa and air tightness at 1.8 m³/(m·h) — these values inform suitability for wind-driven rain exposure and air infiltration control.
Fork-type handle with multiple finish options, connecting directly to the transmission mechanism — the finish choice informs hardware coordination with adjacent fixtures.
Customized transmission boxes with sequential multi-point locking — this determines compression consistency around the sash seal.
13-inch flat open friction hinges standard for outward sashes — this informs sash size compatibility and controlled opening behavior.
System compatible with external fly screens — this informs insect-protection add-on selection.
Custom shapes include rectangular combinations, angled tops, and geometric forms — this informs non-standard opening design options.
Slim frame design maximizes daylighting area and visual permeability — this informs daylight and view requirements for the space.

Basic Parameters
Performance Dimension | Product Value | Meaning & Evidence to Request |
|---|---|---|
Thermal Insulation | Project-specific confirmation required | Thermal performance should be compared using the declared rating, test method, specimen configuration, and project boundary conditions. Request the applicable thermal test or simulation report and the declared product configuration. |
Wind Pressure Resistance | Project-specific confirmation required | Wind pressure resistance should be reviewed against the specified test pressure, specimen size, anchorage, and acceptance criteria. Request the wind-pressure test report and confirm the tested specimen and installation conditions. |
Water Tightness | 650 Pa | Water tightness should be reviewed against the test pressure, spray exposure, specimen configuration, and leakage criteria. Request the water-penetration test report and confirm the tested pressure and assembly configuration. |
Air Tightness | 1.8 m³/(m·h) | Air tightness should be reviewed against the pressure differential, specimen area, reporting units, and tested configuration. Request the air-leakage test report and confirm its pressure and specimen configuration. |
Sound Insulation | Project-specific confirmation required | Sound insulation should be compared using the stated laboratory method, specimen construction, glazing, and reported acoustic metric. Request the acoustic test report and confirm that the tested construction matches the proposed configuration. |
