The commercial windows aluminum frame is an aluminum casement window from the WY-118L series, specified for commercial building projects where buyers evaluate aluminum fenestration products.
- Aluminum frame with outward opening / awning operation for commercial window applications
- Products meet NFRC, AS2047, and CE certifications
- Additional testing and certification available when a project requires it
Product Details
The WY-118L series aluminum casement window is built with a 118MM-wide, 1.8MM-thick aluminum frame that operates via outward opening or awning action. The sash is carried by a 13-inch flat open friction hinge independently developed by DERCHI, and a Black Six Point Lock with an invention patent pairs with a WEHAGE lock point and lock seat system to secure the sash. The standard glazing unit is double tempered glass with argon gas fill (5mm+27A+5mm) separated by a PVDF aluminum strip, and a DERCHI insulation strip is integrated into the frame. Manufacturing 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, carried out in a 70,000+ m² factory staffed by 600+ employees.
Procurement teams should evaluate the WY-118L by selecting from seven glass configurations (single, tempered, double-glazed, triple, insulating, laminated, and frosted), ten customizable layout combinations of fixed panels, casement sashes, and awning openings, and color finishes that include two PVDF options (Retro Green, Mint Gold) plus ten stock colors. Handle choices extend to DERCHI-customized designs and a standard WEHAG no-base handle in black, silver, or antique bronze, while optional packaging includes the New 48 Pack or New 88 Pack. Confirm the glass configuration, layout combination, color finish, and handle finish before drawing approval, because delivery runs 25-35 days after deposit and drawing confirmation and the 10-year warranty covers frame color retention and hardware function under correct operation.
Product Features
- WY-118L aluminum casement window with outward/awning opening — select this opening type when interior clearance is limited or rain-safe ventilation is required.
- WEHAG no-base handle available in black, silver, and antique bronze finishes — choose the finish that coordinates with your interior hardware palette.
- Black six-point lock with invention patent — specify this locking mechanism when multi-point security is a project requirement.
- 13-inch flat open friction hinge developed by DERCHI — select this hinge for stable outward sash operation in the WY-118L system.
- U-factor of 0.23 and SHGC of 0.20 — select this glazing configuration when energy-code compliance requires heat-transfer and solar-gain values at these levels.
- Water tightness rated at 700Pa — specify this rating when projects exposed to wind-driven rain require resistance at or above 700Pa.
- Air tightness at 1.2 m³/(m·h) — select when air-leakage specifications require performance at or below 1.2 m³/(m·h).
- Wind pressure resistance at 5K Pa — specify when commercial facades require wind-load resistance at or above 5K Pa.
- Sound insulation at 35 dB — select when occupied spaces require acoustic separation of 35 dB from exterior noise.
- DERCHI independently developed customized handle designs for the WY-118L series — select this option when standard handle finishes do not meet project design requirements.
Customizable Styles
- Seven glass configurations are orderable: single, tempered, double-glazed, triple, insulating, laminated, and frosted glass.

- DERCHI customized transmission box transfers handle rotation to the multi-point lock.
- Hardware is sourced through cooperation with global hardware brands.
- Handle finish selection and hinge configuration should be confirmed against project opening requirements before specification.
Basic Parameters
| Performance Dimension | Product Value | Meaning & Test Evidence to Request |
|---|---|---|
| Thermal Insulation | U-factor 0.23; SHGC 0.20; 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 | 5.0 kPa | 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 | 700Pa | 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 | 1.2 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 | 35 dB | 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. |
