Product Details
The WY-118L aluminum casement window is built with a 1.8mm profile thickness and 118mm frame width, using an S18 multi-cavity DERCHI insulation strip and a PVDF aluminum strip between the double tempered glass units (5mm+27A+5mm with argon gas fill). The window operates with an outward opening or awning mechanism, supported by a 13-inch flat open friction hinge independently developed by DERCHI, a WEHAG hinge, and a WEHAG handle available in black, silver, and antique bronze finishes. A black six-point lock with an invention patent secures the sash through a DERCHI-customized transmission box, and the production process follows a defined sequence from surface treatment through profile cutting, glass installation, frame assembly, troubleshooting and sealing, to packing.
Procurement teams should confirm the glass configuration from the seven available options (single, tempered, double-glazed, triple, insulating, laminated, and frosted) and select from ten customizable layout configurations that combine fixed panels, casement sashes, and awning openings within the WY-118L series. Color finishes include two PVDF options (Retro Green, Mint Gold) and ten stock color options, and the optional packaging is available as New 48 Pack or New 88 Pack. Buyers should verify the delivery timeline of 25-35 days after deposit and drawing confirmation, the 10-year quality warranty covering frame unfading, hardware, and accessories, and the engineering and supervising service for installation guidance, with 100% full inspection before shipment and certifications including NFRC, CE, AS2047, CSA, and ISO9001.

FAQ
What must be confirmed technically before ordering aluminium window designs for homes?
The window system can be supplied as a complete package including profile, hardware, accessories, glass, and finished products. Buyers must confirm drawings, dimensions, color, and glass type, as pricing is based on these specific requirements. Products meet NFRC, AS2047, and CE standards for international market compliance.
What should buyers prepare for volume procurement?
Prepare drawings, dimensions, color, and glass type specifications for quotation. Optional packaging includes New 48 Pack or New 88 Pack. Every unit undergoes 100% full inspection before shipment, and one-stop customer service covers ordering through shipment.
What information is needed for a custom window quotation?
Pricing is based on buyer's specific requirements including drawings, dimensions, color, and glass type. The system can be supplied as profile, hardware, accessories, glass, or finished products depending on project needs.
How to choose between thermal-break and non-thermal-break aluminium windows?
Pure aluminium has high thermal conductivity, and non-thermal-break windows offer poor insulation. Thermal-break aluminium windows cost more than PVC alternatives but provide better insulation performance. Select thermal-break profiles for energy efficiency and heating/cooling cost reduction; non-thermal-break may suffice for moderate climates.
What optional parts are available and how do they integrate?
The window system includes profile, hardware, accessories, and glass as configurable components. Engineering and supervising service for installation is available to support integration of optional parts into the window assembly.
How do lead times and shipping work for international B2B orders?
One-stop customer service covers the process from ordering to shipment. The company trades with customers in more than 100 countries, and OEM/ODM capability supports customized orders for global distributor networks.
