Product Details
The DERCHI WY-50 series casement window uses an aluminium frame with powder coated finish at 1.4mm profile thickness and 50mm frame width, fitted with double tempered glass in a 5mm+20A+5mm configuration filled with argon gas and separated by a PVDF aluminum strip. EPDM weather seals and a silicone glass bonding process seal the glazing unit, while the sash operates with outward opening or awning action supported by a friction stay design that maintains sash position without additional support arms. DERCHI-developed hardware includes a customized fork-type handle that connects directly to a transmission mechanism, with customized transmission boxes transferring handle rotation to integrated lock points and a lock base around the sash perimeter.
Procurement teams should confirm glass configuration, as the system supports single glass, triple glazing, laminated glass, and frosted glass in addition to the standard double tempered unit, and should specify exterior finish between the standard Black Skin stock color and PVDF coated options for exterior exposure. Buyers can also confirm compatibility with external fly screens and whether the order requires the full window system supply including profile, hardware, accessories, and glass, or finished products ready for installation. The production process covers surface treatment, profile processing and cutting, glass cutting and aluminum strip installation, opening fan installation, frame and casing assembly, debugging and sealing, and packing, with products meeting NFRC, AS2047, and CE certifications and backed by a 10-year quality warranty covering frame color retention, hardware, and accessories under correct operation.
Product Features
WY-50 series casement window with outward/awning opening — sets the opening direction and exterior clearance requirement for each sash.
1.4mm profile thickness and 50mm frame width — defines the wall reveal dimension and reinforcement specification.
Slim frame design maximizes daylighting area — determines glass-to-frame ratio for daylighting calculations.
Water tightness rated at 650 Pa — guides specification for wind-driven rain exposure conditions.
Air tightness rated at 1.8 m³/(m·h) — informs air-leakage compliance for energy-code targets.
WY-50 system supports rectangular, angled-top, and geometric form configurations — confirms whether non-standard shapes can be specified within one system.
Compatible with external fly screens — determines insect-screen integration without separate framing.
Standard fork-type handle supplied with multiple finish options — sets hardware finish coordination with interior trim.
Friction stay design holds sash position without additional support arms — informs whether supplementary stay hardware is required.
10-year quality warranty covering frame, hardware, and accessories — informs long-term maintenance planning.

Basic Parameters
Performance Dimension | Product Value | Meaning & Test Evidence to Request |
|---|---|---|
Thermal Insulation | Requires testing | Compare using the declared rating, test method, specimen configuration, and project boundary conditions. Request the applicable thermal test or simulation report (NFRC / ISO 10077-2). |
Wind Pressure Resistance | Requires testing | Review against the specified test pressure, specimen size, anchorage, and acceptance criteria. Request the wind-pressure test report (ASTM E06.51 / FGIA NAFS / ISO 6613). |
Water Tightness | 650 Pa | Review against the test pressure, spray exposure, specimen configuration, and leakage criteria. Request the water-penetration test report (ASTM E06.51 / FGIA NAFS / ISO 6613). |
Air Tightness | 1.8 m³/(m·h) | Review against the pressure differential, specimen area, reporting units, and tested configuration. Request the air-leakage test report (ASTM E06.51 / FGIA NAFS / ISO 6613). |
Sound Insulation | Requires testing | Compare using the stated laboratory method, specimen construction, glazing, and reported acoustic metric. Request the acoustic test report (ISO 10140-1 / ASTM E90). |

FAQ
What technical details need to be confirmed before placing an order?
Configuration adaptability for project-specific performance requirements and regional building codes must be confirmed before ordering. The window system supply scope—including profile, hardware, accessories, glass, or finished products—should also be defined.
What should we prepare for a volume procurement order?
Buyers should prepare a shop drawing or window schedule, as pricing is based on specific requirements. Project orders with custom colors carry minimum quantity requirements, and material efficiency is optimized to control project procurement costs.
How long does delivery take after order confirmation?
Delivery takes 25-35 days after deposit and drawing confirmation.
What warranty coverage applies to commercial projects?
A 10-year quality warranty is provided for B2B project assurance.
Do you provide installation support?
Engineering and supervising service is available for installation guidance.
