The 24 x 40 casement window is a made-to-size aluminum crank-out window from DERCHI, available in WY-72, WY-86, or WY-100 series to match different frame depths and glass packages. It is built for B2B project buyers who need exact sizing and reliable ventilation control.
- Constructed with 6063-T5 aluminum profile and EPDM rubber strip sealing
- Features double tempered glass and hand-crank operation for controlled airflow
- Designed for residential and commercial exterior openings requiring made-to-size fit
Product Details
This crank out casement window is built with a 6063-T5 aluminum profile at 1.4 mm wall thickness, sealed with EPDM rubber strips. Buyers can select from three frame depth options—72 mm, 86 mm, or 100 mm. Depending on the series, the unit comes with double tempered glass: 5+27A+5 mm for WY-72 and WY-100, or 5+15A+5 mm for WY-86. The hand-crank flat-opening operation allows for controlled ventilation.
The three DERCHI casement window series differ in frame depth, glass spacing, and hardware. WY-72 uses an American hand crank with a multi-point lock, while WY-86 and WY-100 use an Australian hanging crank with a single-point lock. Made-to-size production ensures the 24x40 aluminum window fits project openings precisely, reducing installation gaps. Buyers should confirm the final series, opening direction, and glass package at quotation.
Product Features
6063-T5 Aluminum Frame: Provides corrosion resistance and structural strength for long-term exterior exposure in residential and commercial building projects.
EPDM Rubber Strip Sealing: Delivers weather-tight performance by resisting wind-driven rain and minimizing air infiltration around the operable sash.
Double Tempered Glass: Offers safety glazing with improved energy insulation and sound reduction compared to standard single-pane glass units.
Hand-Crank Operation: Allows controlled ventilation without reaching outward, making it suitable for hard-to-reach openings above counters or furniture.
Three Frame Depth Options: Selecting 72, 86, or 100 mm profiles provides flexibility to match specific project thermal and structural requirements.
Made-to-Size Production: Manufacturing to exact 610 x 1016 mm dimensions ensures an accurate fit for project openings, reducing on-site rework.
Customizable Styles
Layout Options: Choose single casement, awning, or fixed and operable composites; additional layouts like double sash or three-segment are available.
Frame Depth Selection: Select 72, 86, or 100 mm frame depths to match the desired glass package and project performance targets.
Glass Package Upgrades: Argon fill, warm-edge spacers, Low-E, laminated, or triple glazing can be selected to meet specific climate needs.
Color and Finish: Twelve standard colors including Pearl White and Quartz Gray, plus PVDF and wood grain finishes with applicable upcharges.
Screen and Safety Options: Anti-theft screens, 304 mesh, King Kong mesh, or safety fences; confirm compatibility with the selected series.
Hardware Accessories
American Hand Crank (WY-72): Provides smooth rotary operation paired with a multi-point switch lock seat for secure sash closure.
Australian Hanging Crank (WY-86/100): Configured for larger frame depths, paired with a single-point switch lock seat for reliable operation.
Multi-Point Switch Lock Seat: Distributes locking pressure across the sash to improve security and maintain consistent sealing compression.
Casement Limiter Options: Simple limiters or safety limiters control the opening range to manage ventilation and prevent unintended wide opening.
Optional Hardware Upgrades: Outward top-hung hardware sets, handle upgrades, and sound or thermal cotton additions are available for performance enhancement.
