Product Details
The aluminium profile casement window is built with a 1.4mm profile thickness and 50mm frame width, using an outward opening or awning configuration. The standard glass unit is double tempered glass with argon gas fill at 5mm+20A+5mm, separated by a PVDF aluminum strip, and sealed with EPDM weather seals and a silicone glass bonding process for multi-layer sealing. Operation is driven by a customized fork-type handle that connects directly to a transmission mechanism, with customized transmission boxes transferring handle rotation to integrated lock points and a lock base around the sash perimeter. Outward-opening sashes use 13-inch flat open friction hinges as standard, whose friction stay design provides controlled opening resistance and maintains sash position without additional support arms. The production process covers surface treatment, profile processing and cutting, glass cutting with aluminum strip installation, opening fan installation, frame and casing assembly, debugging and sealing, and packing.
Beyond the standard double tempered argon unit, the window supports diversified glass configurations including single glass, triple glazing, laminated glass, and frosted glass, and the WY-50 series standard stock color is Black Skin finish. Fork-type handles are supplied as standard with multiple finish options, and the system is compatible with external fly screens. DERCHI can supply the window system including profile, hardware, accessories, and glass, or finished products ready for installation. Price is based on the buyer's specific requirement, delivery time is 25-35 days after deposit and drawing confirmation, and products meet NFRC, AS2047, and CE standards with additional testing and certification available if required. Procurement teams should confirm glass configuration, handle finish, and color before selection.

Basic Parameters
Performance Dimension | Product Value / Status | Test Method & Evidence to Request |
|---|---|---|
Thermal Insulation | Confirm the required thermal rating and supporting test report for the target project. | 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 | Confirm the required wind pressure rating and supporting test report for the target project. | 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 | Confirm the required acoustic rating and supporting test report for the target project. | 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?
Price is based on the buyer's specific requirement, including shop drawing or window schedule, frame color, glass type, glass thickness, glass color, and argon filling. The aluminium profile windows are compatible with regional building codes; confirm the applicable codes for the project location before ordering. Flexible adjustment of the window configuration is available based on project-specific performance requirements; specify the required performance targets during technical confirmation.
What should buyers prepare for volume procurement?
Custom color options are available for project orders meeting minimum quantity requirements. The slim frame design supports cost-controlled project procurement. Buyers can order a complete window system including profile, hardware, accessories, and glass, or finished products. Delivery takes 25-35 days after deposit and drawing confirmation.
Which product details require confirmation before selection?
Confirm the window schedule, frame finish, and glass configuration before placing an order. Prepare the required project documentation and coordinate the installation plan with the project team.
