Product Details
This 28 x 36 casement window is built with a 6063-T5 aluminum profile and EPDM rubber strip sealing. The 1.4 mm profile thickness provides structural stability, while the three frame depth options (72 mm, 86 mm, or 100 mm) allow project-specific performance matching. Double tempered glass configurations vary by series, with 5+27A+5 mm for WY-72/100 and 5+15A+5 mm for WY-86, supporting both thermal and acoustic requirements.
The hand-crank mechanism differentiates this unit from sliding windows by enabling full-side opening for maximum ventilation. This makes the aluminum casement window particularly practical for hard-to-reach installations such as above kitchen sinks or in stairwells. Final series selection, glass package, and left or right opening direction are confirmed at the quotation stage based on project layout and operator preference.
Product Features
Hand-Crank Operation: Enables controlled ventilation and outward opening, making the crank out window practical for hard-to-reach placements like above sinks or stairwells.
6063-T5 Aluminum Frame: Provides structural stability and corrosion resistance for long-term use in residential and light commercial building applications.
EPDM Rubber Sealing: Creates a continuous weather barrier along the frame and sash perimeter, helping to reduce air and water infiltration.
Double Tempered Glass: Offers safety and noise reduction, with configurable gas and spacer upgrades available for enhanced thermal performance.
Three Frame Depth Options: Available in 72 mm, 86 mm, or 100 mm depths, allowing buyers to match structural and performance needs.
Multi-Style Customization: Supports single casement, awning, fixed-plus-operable composite, and dual sash layouts for diverse architectural needs.
Customizable Styles
Opening Configuration: Choose from single casement, awning, or fixed-plus-operable composite layouts to meet specific ventilation and spatial requirements.
Frame Depth Selection: Select 72 mm, 86 mm, or 100 mm frame depth based on wall conditions and project-specific structural performance targets.
Glass Package Upgrades: Options include double tempered, Low-E, laminated, triple, or blind-glass to meet varied thermal and acoustic project standards.
Color and Finish: Twelve standard colors including Pearl White and Deep Sea Blue, plus PVDF custom color with a +150 RMB/m² upcharge for facades.
Made-to-Order Sizing: Custom dimensions available from a low indicative MOQ, with cranked-out panel range W450-800 mm x H600-1500 mm.
Hardware Accessories
Hand Crank Mechanism: American hand crank for WY-72 or Australian hanging hand crank for WY-86/100 ensures smooth outward opening operation.
Lock Seat System: Multi-point switch lock seat (WY-72) or single-point lock seat (WY-86/100) provides secure closure and basic intrusion resistance.
Casement Limiters: Optional simple limiter (+60 RMB/pc) or safety limiter (+168 RMB/pc) for controlling the opening range and airflow.
Sealing System: EPDM rubber strip provides a continuous weather barrier along the frame and sash perimeter to minimize air and water ingress.
Screen and Safety Options: 304 high-definition mesh, King Kong mesh, and safety fence available; series compatibility confirmed per order.
Basic Parameters
Performance Item | Available Information | Buyer Notes |
|---|---|---|
Thermal Insulation | U-Factor 0.39, SHGC 0.25 | Confirm units (SI vs IP) and verify compliance with local energy code for project climate zone. |
Wind Pressure Resistance | 5 KPa | Verify against local wind load code — may require higher rating for high-rise or coastal zones. |
Water Tightness | 350 Pa | Confirm this meets local code requirements for the project wind and rain exposure zone. |
Air Tightness | 4.5 m³/(m·h) | Confirm applicable air-tightness class standard (AAMA, EN, or GB) meets project specification. |
Sound Insulation | 30 dB | Consider laminated or triple glass upgrades if higher acoustic performance is required. |
