Product Details
The aluminium windows with double glazing are constructed as casement windows with a 1.4mm aluminium profile and 50mm frame width, glazed with double tempered glass filled with argon gas in a 5mm+20A+5mm configuration separated by a PVDF aluminum strip. EPDM weather seals combined with a silicone glass bonding process form multi-layer sealing around the sash. Operation is via outward opening or awning action, where a customized fork-type handle connects directly to a transmission mechanism; customized transmission boxes transfer handle rotation to integrated lock points and lock bases distributed around the sash perimeter. A friction stay design creates controlled opening resistance and maintains the sash in position without additional support arms, using DERCHI-developed customized hardware components engineered for consistent operation over repeated cycles.
The window system accepts diversified glass configurations including single glass, triple glazing, laminated glass, and frosted glass; procurement teams should confirm the glazing specification against project requirements before ordering. The standard stock color for the WY-50 series is a Black Skin finish, with PVDF coating available as a custom exterior color option. The system is compatible with external fly screens and can be supplied as a complete package including profile, hardware, accessories, and glass, or as finished products ready for installation. Before finalizing selection, confirm glass type, finish color, and hardware specifications to match project requirements.

Basic Parameters
Performance Dimension | Value / Meaning | Test Method & Evidence to Request |
|---|---|---|
Thermal Insulation | Compare 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 (NFRC, ISO 10077-2). |
Wind Pressure Resistance | Review 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 (ASTM E06.51, FGIA NAFS, ISO 6613). |
Water Tightness | 650 Pa | Request the water-penetration test report and confirm the tested pressure and assembly configuration (ASTM E06.51, FGIA NAFS, ISO 6613). |
Air Tightness | 1.8 m³/(m·h) | Request the air-leakage test report and confirm its pressure and specimen configuration (ASTM E06.51, FGIA NAFS, ISO 6613). |
Sound Insulation | Compare 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 (ISO 10140-1, ASTM E90). |

FAQ
What must be confirmed technically?
The supply format must be confirmed first, as the manufacturer can supply either a complete window system (profile, hardware, accessories, glass) or finished products. For exterior exposure applications, PVDF-coated options are available. Pricing is based on the buyer's specific requirements including drawings, color, and glass type. Compatibility with regional building codes is supported, and specific project-location requirements should be confirmed.
What should buyers prepare for volume procurement?
Buyers should prepare finalized drawings, color specifications, and glass type details for quotation. Delivery takes 25-35 days after deposit and drawing confirmation. Custom color options are available for project orders meeting minimum quantity requirements. A 10-year quality warranty applies, with 100% full inspection conducted before shipment.
Which product details require confirmation before selection?
Confirm the intended installation environment and exposure conditions before selecting surface finish and glass configuration. Assess whether the project's exterior exposure conditions require a more durable surface coating.
