Product Details
The DERCHI aluminum alloy casement window is built with 1.4mm profile thickness and a 50mm frame width, using double tempered glass (5mm+20A+5mm) with argon gas and a PVDF aluminum strip between the panes. The outward opening sash operates through a customized fork-type handle that connects directly to a transmission box, which transfers handle rotation to integrated lock points around the sash perimeter with sequential engagement, while 13-inch flat open friction hinges provide controlled opening resistance and maintain sash position. Weather sealing uses EPDM seals and a silicone glass bonding process, and the production sequence covers surface treatment, profile cutting, glass cutting with aluminum strip installation, opening fan installation, frame and casing assembly, debugging and sealing, and packing.
The system supports diversified glass configurations including single glass, triple glazing, laminated glass, and frosted glass, with the WY-50 series standard stock color in Black Skin finish and compatibility with external fly screens. DERCHI supplies the window system as individual components or as finished products ready for installation, with delivery in 25-35 days after deposit and drawing confirmation and a 10-year quality warranty covering frame unfading, peel-off, and hardware operation under correct use. Procurement teams should confirm glass configuration, finish color, opening direction, and supply mode before placing orders.
Product Features
WY-50 Series aluminum alloy casement window with 1.4mm profile thickness and 50mm frame width — select this series for projects specifying a 50mm-frame aluminum casement with 1.4mm wall profiles.
Outward opening / awning configuration — choose outward opening when inward swing clearance is restricted.
Multiple window style configurations including rectangular combinations, angled tops, and geometric forms — match the style variant to the architectural opening shape.
Double tempered glass (5mm+20A+5mm) with argon gas and PVDF aluminum strip between panes — specify this glazing assembly when tempered safety glass and argon-filled cavities are required.
EPDM weather seals with silicone glass bonding form a multi-layer sealing barrier achieving 650 Pa water tightness and 1.8 m³/(m·h) air tightness — select this sealing configuration for wind-driven rain exposure conditions.
13-inch flat open friction hinges standard for outward opening sashes maintain sash position without additional support arms — choose friction-stay hardware when hold-position without external arms is preferred.
Fork-type handle connects directly to the transmission mechanism; customized transmission boxes transfer rotation to multiple locking points with sequential engagement — select this hardware set when multi-point sequential locking is specified.
Compatible with external fly screens — add fly screens when insect protection is required for the opening.

Basic Parameters
Performance Dimension | Product Value | Meaning & Test Evidence to Request |
|---|---|---|
Thermal Insulation | Requires testing | 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 | Requires testing | 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 | Requires testing | 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. |

FAQ
What must be confirmed technically before ordering?
Buyers must confirm shop drawings, frame color, glass type, glass thickness, glass color, and argon fill option, as pricing is based on these specific requirements. Glass configurations can be diversified for project-specific performance requirements. PVDF coating is available for exterior exposure applications, and external fly screens are compatible for projects requiring regional building code compliance.
What should buyers prepare for volume procurement?
Custom color options require project orders meeting minimum quantity requirements. Slim frame design is available for cost-controlled project procurement. Supply format can be selected as a window system including profile, hardware, accessories, and glass, or as finished products ready for installation. Delivery takes 25-35 days after deposit and drawing confirmation.
Which certification documents are available?
Products meet NFRC, AS2047, and CE standards, with additional testing or certification available on request.
What installation support is provided?
Engineering and supervising service is available to guide installation.
What quality assurance applies?
100% full inspection is conducted before shipment, and products carry a 10-year quality warranty. One-stop customer service covers ordering through shipment.
