The 2x4 casement window from the WY-72, WY-86, and WY-100 series offers a configurable aluminum window solution for residential and light commercial projects. Featuring hand-crank operation and made-to-size production, it addresses project-specific ventilation, thermal, and safety requirements.
- Hand-crank operation for controlled airflow and hard-to-reach placements
- Three frame-depth options: 72 mm, 86 mm, and 100 mm
- Double tempered glass with configurable upgrade packages
- Made-to-size production within the W450-800 mm x H600-1500 mm panel range
Product Details
This cranked-out aluminum window features a 6063-T5 aluminum profile with a 1.4 mm wall thickness and EPDM rubber sealing. The three available series differ by frame depth—72 mm, 86 mm, and 100 mm—and glass spacing. The WY-72 and WY-100 use double tempered glass (5+27A+5 mm), while the WY-86 features a 5+15A+5 mm configuration, allowing buyers to match structural requirements and performance targets.
The hand-crank flat-opening or top-hung operation suits compact residential rooms and hard-to-reach placements like above-counter walls or stairwells. Unlike standard sliding windows, the crank mechanism and EPDM sealing contribute to controlled ventilation and weather performance. Configurable glass and screen packages address thermal, acoustic, and safety requirements, with final specifications confirmed at the order stage.
Product Features
6063-T5 Aluminum Frame: Built with a 1.4 mm profile thickness, this aluminum casement window provides structural stability and corrosion resistance for exterior-facing applications.
Hand-Crank Operation: The crank mechanism enables easy control for hard-to-reach or above-counter window placements, offering controlled ventilation without obstructing interior space.
EPDM Rubber Sealing: EPDM strips deliver water resistance at 350 Pa and air leakage control at 4.5 m3/(m·h), helping to maintain interior comfort during adverse weather.
Double Tempered Glass: Standard double tempered glass achieves a U-Factor of 0.39 and SHGC of 0.25, supporting thermal performance targets in residential projects.
Three Frame-Depth Options: Buyers can select 72 mm, 86 mm, or 100 mm frame depths to match specific wall structures, glass spacing needs, and project performance tiers.
Configurable Glass Upgrades: Low-E, laminated, triple glazing, argon fill, and warm-edge spacer options allow buyers to balance acoustic, thermal, and budget requirements.
Customizable Styles
Glass Configuration: Double tempered glass is standard; Low-E, laminated, triple, or blind-glass upgrades are available for project-specific thermal or acoustic targets.
Frame Depth Selection: Choose 72 mm, 86 mm, or 100 mm frame depth based on wall structure, glass spacing requirements, and local performance targets.
Size Customization: Made-to-size production within the opening panel range of W450-800 mm x H600-1500 mm; nominal 2x4 ft (610x1219 mm) serves as a reference.
Color Options: 12 standard colors including Pearl White, Quartz Gray, and wood grain finishes; PVDF and custom colors available with an upcharge.
Sash Layout: Single sash, double sash, side-opening with center fixed, or combination layouts; final layout depends on operation side and screen selection.
Hardware Accessories
Hand Crank Handle: American-style crank for WY-72 and Australian hanging crank for WY-86/100; select based on project market and operation preference.
Lock Seat: Multi-point switch lock for WY-72 and single-point switch lock for WY-86/100; confirm security requirements per project.
Limiter Options: Simple limiter (+60 RMB/pc) or safety limiter (+168 RMB/pc) for controlled opening width and child safety; reference prices confirmed at quotation.
Screen Options: Anti-theft screen, 304 stainless steel high-definition mesh, King Kong mesh, or 48-mesh high-transparency mesh; fixed or opening safety fence available.
Optional Upgrades: Outward top-hung hardware (+1650 RMB/set), warm-edge spacer (+198 RMB/m2), and argon fill (+36 RMB/m2); reference upcharges confirmed at order.
