Product Details
This aluminum casement window features a multi-cavity frame structure with 1.8mm profile thickness and a 75mm frame width, built around the WY-75 profile system. The outward opening or awning operation uses a stainless steel friction hinge with multiple pivot points and a transmission mechanism engineered for the WY-75 profile. The sealed glazing system pairs double tempered glass with argon gas in a 5mm+20A+5mm configuration, separated by a PVDF aluminum strip. All hardware components are DERCHI developed and customized, including the baseless safety handle, 12-inch heavy-duty hinge, and lock point with lock base, and have passed repeated cycle tests.
Buyers should confirm glass configuration from the seven available options, which include single, double, triple, laminated, and frosted variants, with specific configurations such as 5MM+27A+5MM and 5MM+12A+5MM+12A+5MM. The Black Skin finish is the standard inventory color for immediate availability on standard orders, while handle options include ergonomic lever handles with two base style options. Price is based on the buyer's specific requirement, and delivery time runs 25-35 days after deposit and drawing confirmation.
Product Features

Basic Parameters
Performance Dimension | Product Value | Meaning & Test Method |
|---|
Thermal Insulation | Standard DERCHI insulation strip | Thermal performance should be compared using the declared rating, test method, specimen configuration, and project boundary conditions. |
Wind Pressure Resistance | Upgraded profile rigidity satisfies stringent wind load standards of high-rise commercial buildings and super high-rise residences. | Wind pressure resistance should be reviewed against the specified test pressure, specimen size, anchorage, and acceptance criteria. |
Water Tightness | Requires project-specific testing confirmation. | Water tightness should be reviewed against the test pressure, spray exposure, specimen configuration, and leakage criteria. |
Air Tightness | Requires project-specific testing confirmation. | Air tightness should be reviewed against the pressure differential, specimen area, reporting units, and tested configuration. |
Sound Insulation | 35 dB | Sound insulation should be compared using the stated laboratory method, specimen construction, glazing, and reported acoustic metric. |
FAQ
What must be confirmed technically?
Quotes are based on shop drawings or window schedules that specify dimensions, quantity, window type, frame color, and glass specifications. The window system supply includes profile, hardware, accessories, and glass, delivered as finished products ready for installation. Custom color matching is available for project-specific design requirements.
What should buyers prepare for volume procurement?
Buyers should prepare shop drawings or window schedules with dimensions, quantity, type, frame color, and glass specifications for quoting. Delivery takes 25 to 35 days after deposit and drawing confirmation. The product supports multiple window style configurations for project procurement. Additional certifications can be arranged if the buyer requires them.
Which product details require confirmation before selection?
Confirm the opening direction, glass type, and frame color before placing an order. Review the window schedule against project requirements to avoid mismatched dimensions or configurations.
