The 24 x 48 casement window is a 610 x 1219 mm aluminum unit from the DERCHI WY-72, WY-86, and WY-100 cranked-out window family. It features hand-crank operation and multiple frame depth options (72/86/100 mm), allowing buyers to match glass packages and hardware to specific project performance requirements. Customizable styles, colors, and screen options support both residential and commercial builds.
- 6063-T5 aluminum profile with EPDM rubber strip sealing
- Double tempered glass (5+27A+5 mm or 5+15A+5 mm by series)
- Hand-crank cranked-out operation for controlled ventilation
- Suitable for apartments, hotels, offices, villas, and exterior facades
Product Details
The 24 x 48 casement window uses a 6063-T5 aluminum profile with 1.4 mm wall thickness per the 2026 DERCHI catalog. Frame depth is selectable at 72, 86, or 100 mm by WY series. EPDM rubber strips seal the sash, and double tempered glass varies by series — 5+27A+5 mm for WY-72 and WY-100, 5+15A+5 mm for WY-86. The hand-crank mechanism on this cranked-out casement window pushes the sash outward via a geared operator, making single-sash operation practical for the 0.74 m2 opening.
Unlike conventional push-out casements, the cranked-out design lets users regulate airflow from inside without reaching the sash — useful above counters or in stairwells. Three series options let procurement teams align frame depth, glass spacing, and hardware with project wind load and thermal targets. Layout flexibility extends to awning, fixed-plus-operable composites, and multi-segment configurations.
Product Features
6063-T5 Aluminum Frame: The 1.4 mm profile thickness (per catalog) provides structural rigidity and corrosion resistance for exterior installations; confirm final thickness for your selected series before ordering.
Hand-Crank Operation: This hand-crank aluminum window opens the sash outward via a geared operator, giving controlled ventilation without direct reach — practical for above-counter or stairwell placements.
Double Tempered Glass: Configurations of 5+27A+5 mm (WY-72/WY-100) or 5+15A+5 mm (WY-86) deliver impact resistance and thermal performance; argon, warm-edge, and Low-E upgrades are available.
EPDM Sealing System: Continuous EPDM rubber strips maintain air and water tightness across seasonal temperature shifts, supporting consistent weather sealing performance in both exposed and interior installation environments.
Frame Depth Options: Three profile depths — 72 mm, 86 mm, or 100 mm — let buyers tier performance by project wind load, thermal targets, and glass spacing requirements.
Energy Performance Data: U-Factor of 0.39 and SHGC of 0.25 support energy-conscious project specifications; confirm which glass configuration these values apply to and explore available upgrade paths.
Customizable Styles
Glass Configuration: Choose between 5+27A+5 mm or 5+15A+5 mm double tempered glass by series, with argon, warm-edge spacer, Low-E, laminated, and blind-glass upgrade options available.
Frame Depth: Select 72 mm, 86 mm, or 100 mm profile depth to match project thermal, structural, and wind load requirements across the WY series.
Size Customization: While nominal size is 24 x 48 in (610 x 1219 mm), custom dimensions are available from 2 m2 for project-specific rough openings; confirm with DERCHI.
Color Options: Twelve official color families include Pearl White, Quartz Gray, Starry Sky Black, wood grain finishes, and more; PVDF and custom colors carry per-m2 upcharges.
Layout Styles: Single sash, awning, fixed-plus-operable composites, three-segment, or irregular/stepped combinations adapt this aluminum casement window 24x48 to varied architectural and opening-direction needs.
Hardware Accessories
Hand Crank Handle: American-style crank (WY-72) or Australian hanging crank (WY-86/WY-100) operates the sash smoothly from the interior; confirm hardware brand availability with DERCHI.
Lock Seat: Multi-point switch lock (WY-72) or single-point switch lock (WY-86/WY-100) secures the casement sash; confirm lock type matches your selected series.
Casement Limiter: Optional simple limiter (+60 RMB/pc) or safety limiter (+168 RMB/pc) controls opening angle for child safety and wind protection; confirm compatibility.
Sealing Hardware: EPDM rubber strips provide continuous weather sealing around the sash; confirm strip grade and compatibility with your selected WY series before production.
Screen and Safety Options: Anti-theft screen, 304 stainless mesh, King Kong mesh, or safety fence options exist; confirm which fit your selected WY series before ordering.

Application Scenarios
Apartment: The 24 x 48 casement window suits compact apartment openings where hand-crank ventilation works well in kitchens, bathrooms, and bedrooms without obstructing interior furniture or walkways.
Home Office: Natural light and regulated airflow through the cranked-out sash create a comfortable work environment for home offices; the 6063-T5 aluminum frame handles year-round temperature variation without warping.
Hotel: The standardized nominal size and twelve finish options support consistent guest-room window specifications across hotel renovation or new-build projects, with export-grade packaging for secure international delivery.
