Product Details
The DERCHI WY-118L aluminum casement window is constructed with a 1.8mm aluminum profile and 118mm frame width, incorporating a DERCHI insulation strip and PVDF aluminum strip between double tempered glass units (5mm+27A+5mm) filled with argon gas. The sash operates via outward opening or awning action, secured by a WEHAG handle, WEHAG hinge, and a black six-point lock system that carries an invention patent, with DERCHI independently developing the 13-inch flat open friction hinge and customizing the transmission box for this series. Production follows a defined sequence of surface treatment, profile processing and cutting, glass cutting and aluminum strip installation, opening panel installation, frame and casing assembly, troubleshooting and sealing, and packing, and DERCHI can supply the complete window system including profile, hardware, accessories, glass, and finished products ready for installation.
Procurement teams should confirm glass configuration, color finish, and layout configuration against project requirements before ordering, as the WY-118L series offers seven glass types, two PVDF color options plus ten stock finishes, and ten customizable layout configurations including fixed panels, casement sashes, and awning openings. The product is authorized under NFRC, CE, AS2047, CSA, and ISO9001, undergoes 100% full inspection before shipment, and ships within 25-35 days after deposit and drawing confirmation with a 10-year quality warranty covering frame color retention and hardware functionality under correct operation.
Product Features
- WY-118L Aluminum Casement Window with 118mm frame width and 1.8mm profile thickness — sets rough-opening and wall-depth dimensions for the installation plan.
- Outward Opening / Awning configuration — projects the sash externally, informing suitability where interior swing clearance is limited.
- WEHAG handle offered in black, silver, and antique bronze finishes — defines the hardware color choice to coordinate with interior trim.
- Six-point locking mechanism with invention patent — sets the security tier for ground-floor or accessible window positions.
- U-factor of 0.23 and SHGC of 0.20 — guides energy-code compliance and solar-heat-gain specification for the building envelope.
- Sound insulation rating of 35 dB — determines fitness for facades exposed to traffic or urban noise.
- Water tightness at 700Pa, air tightness at 1.2 m³/(m·h), and wind pressure resistance at 5K Pa — defines the weather-performance envelope for exposed or high-rise sites.
- Standard DERCHI insulation strip — confirms the thermal-break component for projects requiring temperature separation between interior and exterior frame zones.
- 13-inch flat open friction hinge independently developed by DERCHI — specifies the hinge mechanism for controlled outward sash movement.
