Product Details
The WY-50 series aluminium casement window is built with a 1.4mm aluminium profile at a 50mm frame width, glazed with double tempered glass and argon gas (5mm+20A+5mm) separated by a PVDF aluminum strip. EPDM weather seals and a silicone glass bonding process seal the glazing unit, and the sash operates via outward opening or awning action. DERCHI-developed hardware includes a customized fork-type handle that connects directly to a transmission mechanism, customized transmission boxes that transfer handle rotation to multiple locking points around the sash perimeter, and 13-inch flat open friction hinges that provide controlled opening resistance and maintain sash position without additional support arms.
Procurement teams should confirm glass configuration at order stage, as the system supports single glass, triple glazing, laminated glass, and frosted glass alongside the standard double tempered unit. Exterior finish options include the standard Black Skin stock color and PVDF-coated options for exterior exposure, while custom shapes extend to rectangular combinations, angled tops, and geometric forms. Buyers requiring external fly screens should specify this at order confirmation, and projects needing third-party certification can request product testing and certification to meet specific market standards.
Product Features
WY-50 Series casement window system supports multiple window style configurations within one profile platform; style variants can be selected without changing the system.
Custom shapes include rectangular combinations, angled tops, and geometric forms; non-standard opening geometries can be specified.
Profile thickness of 1.4 mm and frame width of 50 mm define the structural dimension class for span and load planning.
Outward opening and awning configurations project sashes externally; exterior clearance and ventilation direction are determined by this opening type.
Slim frame design maximizes daylighting area and visual permeability; daylight and view optimization are affected by frame profile selection.
Water tightness rated at 650 Pa and air tightness at 1.8 m³/(m·h) specify the weather-performance tier for wind-driven rain and air-infiltration exposure.
Fork-type handles are supplied as standard with multiple finish options; handle finish is a selectable aesthetic parameter.
Handle connects directly to a transmission mechanism driving multiple locking points around the sash perimeter; security level is determined by the multi-point lock configuration.
13-inch flat open friction hinges are standard for outward opening sashes and maintain sash position without additional support arms; no auxiliary stay is required.
Compatibility with external fly screens determines insect-protection accessory integration options.
Supply scope includes profile, hardware, accessories, glass, and finished products ready for installation; component-level or complete-system sourcing can be selected.

Buyers should confirm hardware finish and hinge type against project opening requirements before finalizing specifications.
Basic Parameters
Performance Dimension | Meaning & Test Evidence to Request |
|---|---|
Thermal Insulation | 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 | 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 | 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 | 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 | 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. |
