Product Details
The aluminum casement window is built on the WY-75 series profile system with a 1.8MM profile thickness and 75MM frame width, using a DERCHI insulation strip within the aluminum extrusion, and is manufactured in a 70,000+ m² factory with 4,000 m² showroom and 600+ employees. The glazing unit is double tempered glass with argon gas fill, configured as 5mm+20A+5mm with a PVDF aluminum strip between the panes. Operation is outward opening or awning style, actuated through a stainless steel friction hinge with multiple pivot points and a transmission mechanism engineered specifically for the WY-75 profile. The company supplies the complete window system including profile, hardware, accessories, and glass as well as finished products ready for installation.
Procurement teams should confirm window dimensions against project opening sizes and select the correct opening direction before ordering. The 70,000+ m² factory footprint and 600+ employee workforce define the supplier's capacity for volume orders. Seven glass configuration options are available including single, double, triple, laminated, and frosted variants, with specific builds such as 5MM+27A+5MM and 5MM+12A+5MM+12A+5MM; buyers needing privacy-area glazing should specify obscure glass at quotation. Black Skin finish is maintained as standard inventory color for immediate availability on standard orders, while other finishes require confirmation against project design requirements. Delivery time is 25-35 days after deposit and drawing confirmation, and a 10-year warranty covers frame unfading, peel-off, and hardware operation under correct use, with 100% full inspection performed before shipment.

Basic Parameters
| Performance Dimension | Product Value or Meaning | Evidence to Request |
|---|---|---|
| Thermal Insulation | WY-75 Series Aluminum Casement Window uses a standard DERCHI insulation strip. 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 | Upgraded profile rigidity satisfies wind load standards of high-rise commercial and super high-rise residences. Hardware has passed repeated cycle tests. 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 | 35 dB. Multi-cavity frame structure and high-performance sealed glazing system contribute to acoustic reduction. 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. |
