The DERCHI WY-118L Series is an aluminum casement window with outward opening and awning operation, marketed as alu clad sash windows for commercial, residential, and exterior applications. Products currently meet NFRC, AS2047, and CE standards, and the manufacturer will arrange additional testing and certification if a project requires it. Price is based on the buyer's specific requirement, so specification details should be confirmed before quotation.
- WY-118L Series aluminum casement window with outward opening and awning operation
- Applications include commercial, residential, and exterior projects
- Meets NFRC, AS2047, and CE, with further certification available on request
- Pricing is based on buyer's specific requirement
Product Details
The DERCHI WY-118L Series aluminum casement window is built with a 1.8 mm aluminum profile, a 118 mm frame width, and a DERCHI insulation strip, produced through a sequence covering surface treatment, profile cutting, glass assembly with PVDF aluminum strips, frame and casing assembly, sealing, and packing. The sash operates through outward opening or awning action, stabilized by a DERCHI-developed 13-inch flat open friction hinge, with a WEHAGE lock point and lock seat system driving a six-point locking mechanism. DERCHI manufactures these windows in a 70,000 m² factory with 600+ employees and can supply the complete window system—profile, hardware, accessories, and glass—or finished products ready for installation.
Procurement teams should specify glass configuration from seven available options (single, tempered, double-glazed, triple, insulating, laminated, and frosted), select from ten customizable layout configurations combining fixed panels, casement sashes, and awning openings, and choose color finishes from two PVDF options and ten stock colors. Price is based on the specific project requirement, delivery runs 25–35 days after deposit and drawing confirmation, and a 10-year warranty covers frame unfading, peel-off resistance, and proper hardware operation. Products currently meet NFRC, AS2047, and CE standards, with additional testing and certification available on request.
Product Features
- 1.8MM aluminum profile thickness and 118MM frame width define the wall opening depth and structural envelope for sash sizing.
- Outward opening / awning operation requires external clearance and egress route verification before sash specification.
- WEHAG no-base handle in black, silver, or antique bronze constrains interior hardware finish selection to three coordinated options.
- Black six-point lock with invention patent, paired with WEHAG lock point and seat system, sets the security hardware tier for ground-floor and accessible openings.
- 13-inch flat open friction hinge independently developed by DERCHI limits sash weight capacity and outward projection angle.
- Double tempered glass with argon gas and PVDF aluminum spacer establishes the acoustic baseline at 35 dB and thermal baseline at U-factor 0.23 for code-compliant projects.
- Standard DERCHI insulation strip determines the thermal break specification for energy-code alignment.
- PVDF color finishes restrict external coating selection to weather-resistant PVDF-grade options.
Customizable Styles
- Color finishes: two PVDF options (Retro Green, Mint Gold) and ten stock color options ranging from wood-grain textures to solid metallic and matte finishes.

Basic Parameters
| Performance Dimension | Declared Value | Meaning & Test Method | Evidence to Request |
|---|---|---|---|
| Thermal Insulation | U-factor 0.23; SHGC 0.20; Standard DERCHI insulation strip | Thermal insulation measures heat transfer through the window assembly; compare using the declared rating, test method, specimen configuration, and project boundary conditions (NFRC; ISO 10077-2). | Request the applicable thermal test or simulation report and the declared product configuration. |
| Wind Pressure Resistance | 5K Pa | Wind pressure resistance measures structural performance under wind load; review against the specified test pressure, specimen size, anchorage, and acceptance criteria (ASTM E06.51; FGIA NAFS; ISO 6613). | Request the wind-pressure test report and confirm the tested specimen and installation conditions. |
| Water Tightness | 700 Pa | Water tightness measures resistance to rain penetration under pressure; review against the test pressure, spray exposure, specimen configuration, and leakage criteria (ASTM E06.51; FGIA NAFS; ISO 6613). | Request the water-penetration test report and confirm the tested pressure and assembly configuration. |
| Air Tightness | 1.2 m³/(m·h) | Air tightness measures air leakage through the assembly under pressure differential; review against the pressure differential, specimen area, reporting units, and tested configuration (ASTM E06.51; FGIA NAFS; ISO 6613). | Request the air-leakage test report and confirm its pressure and specimen configuration. |
| Sound Insulation | 35 dB | Sound insulation measures acoustic attenuation through the glazed assembly; compare using the stated laboratory method, specimen construction, glazing, and reported acoustic metric (ISO 10140-1; ASTM E90). | Request the acoustic test report and confirm that the tested construction matches the proposed configuration. |
