Product Details
The 24 x 30 casement window is built on a 6063-T5 aluminum profile with 1.4 mm wall thickness, sealed with EPDM rubber strips. Buyers select from three frame depths — 72 mm, 86 mm, or 100 mm — corresponding to the WY-72, WY-86, and WY-100 series. Each pairs with a hand-crank operation mode: flat opening or hanging up, swinging the sash outward via crank rather than direct push.
This cranked-out aluminum window delivers ventilation where direct sash access is difficult — above counters, behind fixtures, or in stairwells. Double tempered glass varies by series (5+27A+5 mm for WY-72/100; 5+15A+5 mm for WY-86), with argon, warm-edge, and Low-E upgrade paths. The 0.46 m² footprint suits tight wall openings where larger units would not fit.
Product Features
Hand-crank operation: Enables opening and closing in hard-to-reach positions above counters or behind fixtures, making this hand crank window practical for kitchens, bathrooms, and stairwells.
6063-T5 aluminum frame: Provides structural rigidity and corrosion resistance for long-term exterior exposure, supporting the sash through repeated crank cycles and varying weather conditions across seasons.
EPDM rubber strip sealing: Delivers consistent weather sealing against rain infiltration and air leakage, helping maintain indoor comfort and reduce drafts along the sash perimeter during operation.
Double tempered glass: Offers safety glazing across all three series, with upgrade paths for argon fill, warm-edge spacers, Low-E coatings, laminated glass, and integrated blind options.
Multiple frame depth options: 72 mm, 86 mm, and 100 mm profiles let buyers tier thermal and structural performance to match wind load requirements, wall cavity dimensions, and budget.
Screen and safety mesh options: Include anti-theft screen, 304 stainless mesh, King Kong mesh, 48-mesh transparent mesh, and fixed or opening safety fences for combined ventilation and security.
Customizable Styles
Layout configurations: Choose single casement, awning, or fixed-plus-operable composite; double sash, three-segment, irregular, hexagonal, and bay-style combinations also available.
Glass package selection: Select 5+27A+5 or 5+15A+5 double tempered; upgrade with argon, warm-edge spacer, Low-E, laminated, triple, or blind glass.
Frame depth: Pick 72 mm, 86 mm, or 100 mm profile depth for this aluminum casement window 610 x 762 mm to match performance tier.
Color and finish: Choose from Pearl White, Quartz Gray, Starry Sky Black, wood grain, and more; PVDF and custom colors available with applicable upcharges.
Screen and safety options: Select anti-theft screen, 304 high-definition mesh, King Kong mesh, 48-mesh transparent mesh, or fixed/opening safety fence per application.
Hardware Accessories
American hand crank (WY-72): Provides smooth crank-out operation with an ergonomic handle suited for residential applications and standard flat-opening sash configurations.
Australian hanging hand crank (WY-86/WY-100): Supports top-hung crank operation in larger frame depths, suited for awning-style opening configurations in WY-86 and WY-100 series.
Multi-point switch lock seat (WY-72): Secures the sash at multiple engagement points, improving sealing pressure and entry resistance along the frame perimeter for WY-72.
Single-point switch lock seat (WY-86/WY-100): Offers straightforward locking for standard operational requirements, keeping the mechanism simple and serviceable for WY-86 and WY-100 series.
Optional casement limiters: Simple limiter or safety limiter available; outward top-hung hardware and handle upgrades also offered with applicable upcharges per project.

Advantages
Compact footprint: 0.46 m² nominal size fits tight wall openings in kitchens, bathrooms, stairwells, and compact urban units where larger windows are impractical.
Crank-out accessibility: Hand-crank operation allows ventilation control in hard-to-reach positions without needing direct sash access or clearance around the opening.
Series flexibility: Three frame depth options (72/86/100 mm) let buyers tier performance to project requirements, wall cavity, and budget constraints.
Export-grade packaging: Wooden frame, protective tape, pallet fixing, PE films, and air bags protect windows during international container shipping and handling.
Made-to-size customization: The DERCHI casement window can be tailored in dimensions, glass, color, screen, and hardware to project specifications with structured upcharge options.
Application Scenarios
Apartment: This compact casement window fits apartment openings where wall space is limited; crank operation enables ventilation in kitchens and bathrooms where direct sash access is restricted by cabinetry.
