Product Details
The 24 x 42 casement window features a 6063-T5 aluminum frame at 1.4 mm profile thickness, EPDM rubber sealing, and double tempered glass. As a cranked-out window, it operates via a hand-crank mechanism that swings the sash outward. Three frame depth options — 72, 86, and 100 mm — let procurement teams match structural and glass spacing requirements.
Unlike sliding or fixed units, this hand crank window allows full sash opening, maximizing airflow in kitchens and bathrooms. Made-to-size production within the 610 x 1067 mm nominal footprint accommodates project rough openings, while tiered glass, hardware, and screen upgrades address energy code compliance. Buyers can configure the DERCHI casement window across single-sash, double-sash, or fixed-plus-operable layouts.
Product Features
Hand-Crank Operation: The cranked-out sash opens via a hand crank, letting occupants control ventilation angle precisely — useful in hard-to-reach installations above counters or stairwells.
Multi-Series Frame Depth: This aluminum casement window offers three frame depths — 72, 86, 100 mm — letting buyers align structural capacity and glass spacing with project specs.
Double Tempered Glass: Standard 5+27A+5 or 5+15A+5 mm tempered glazing provides impact safety. Optional argon, warm-edge, Low-E, and laminated upgrades address energy and acoustic targets.
EPDM Rubber Sealing: Continuous EPDM strips along the frame perimeter help manage water infiltration and air leakage. Confirm weather-tightness ratings against local building code thresholds before ordering.
Glass Upgrade Path: Argon fill, warm-edge spacers, Low-E coating, laminated and triple glazing, and blind-glass units let procurement teams tune thermal and acoustic performance to regional standards.
Export-Grade Packaging: Wooden-frame packaging with protective tape, pallet fixing, plastic belts, PE films, and inter-pallet air bags protects units during international sea freight for bulk orders.
Customizable Styles
Glass Configuration: Double tempered 5+27A+5 (WY-72/100) or 5+15A+5 (WY-86), with argon, Low-E, laminated, triple, and blind-glass upgrades confirmed at quotation.
Frame Depth and Series: Choose WY-72, WY-86, or WY-100 based on structural and performance requirements. Confirm series selection during quotation.
Size Customization: This custom casement window is made-to-size within the W450-800 x H600-1500 mm opening panel range for project-specific rough openings.
Color and Finish: Twelve-plus standard colors include Pearl White, Quartz Gray, Starry Sky Black, and wood grain. PVDF and custom coatings carry upcharges.
Opening Layout: Single sash, double sash, fixed-plus-operable composite, three-segment, or irregular combinations available. Final layout depends on project drawings.
Hardware Accessories
Hand Crank Mechanism: WY-72 uses American-style hand crank; WY-86 and WY-100 use Australian hanging crank. Confirm crank side — left or right — at order.
Lock Seat: WY-72 pairs with multi-point switch lock; WY-86 and WY-100 use single-point switch lock. Confirm hardware brand availability during quotation.
Casement Limiter: Optional simple or safety limiter controls sash opening angle, protecting children and managing wind exposure. Selection confirmed at quote.
Screen and Mesh: Anti-theft, 304 HD mesh, King Kong mesh, and 48-mesh high-transparency mesh available. Compatibility varies by series — confirm during ordering.
Handle and Hardware Upgrades: Handle upgrades and outward top-hung hardware conversion sets offer alternative operation. Discuss compatibility and pricing with supplier before production.

Application Scenarios
Apartment: Compact urban apartments benefit from the 610 x 1067 mm footprint in kitchens and bathrooms. Hand-crank operation reaches over counters without direct sash access.
Home Office: Natural light and controlled ventilation maintain comfort during work hours. The cranked-out sash opens fully to refresh air quickly, and tempered glass provides occupant safety.
Hotel: Guest rooms need reliable ventilation and acoustic control. The 30 dB rating, upgradable glass packages, and multi-point locking support hotel-grade comfort and security requirements.
Office Building: Commercial spaces benefit from durable 6063-T5 aluminum frames and configurable glass. Procurement teams select frame depth and hardware to match building specs and energy codes.
Outdoor: For outdoor-facing enclosures like balconies or stairwells, confirm water tightness at 350 Pa and wind resistance at 5 KPa against local exposure conditions and installation details.
Residential Building: Multi-unit projects can standardize on the nominal size while customizing color, glass, and screen per unit type. Made-to-size production accommodates varying rough opening dimensions.
Exterior: Exterior facade installations require verified weather resistance. Confirm surface finish durability, EPDM sealing performance, and wind load compliance with the project architect before ordering.
Villa: Villa projects demand coordinated finishes across multiple window types. Twelve-plus standard colors, PVDF coatings, and wood grain finishes support cohesive design in living rooms and bedrooms.
