The 30x40 casement window is a made-to-size aluminum thermal-break crank-out window from DERCHI's WY series, built for B2B project buyers who need custom configurations and verified performance data.
- Constructed with 6063-T5 aluminum profile available in 72, 86, or 100 mm frame depths
- Hand-crank opening mechanism for controlled ventilation in hard-to-reach installations
- Double tempered glass packages tailored to series selection for safety and thermal efficiency
- Manufactured to project-specific dimensions from the nominal 30 x 40 in reference size
Product Details
Structurally, this crank out window utilizes a 6063-T5 aluminum profile paired with an EPDM rubber strip for consistent weather sealing. Unlike sliding windows, the flat-opening sash swings outward via a hand crank, allowing full top-to-bottom ventilation and a tighter compression seal against the frame. Buyers select from three frame depth options—72, 86, or 100 mm—each paired with specific double tempered glass packages (5+27A+5 mm or 5+15A+5 mm) to match structural requirements and budget tiers.
The thermal break casement window addresses energy efficiency needs in exterior applications while accommodating diverse interior spaces. It is well suited for kitchens, bathrooms, bedrooms, stairwells, and balconies where controlled airflow and space efficiency are priorities. The three available series allow procurement teams to scale performance specifications across different project tiers, ensuring the selected configuration aligns with local building code requirements without over-specifying lower-budget segments.
Product Features
Hand-Crank Operation: Enables easy ventilation control especially for hard-to-reach installations above counters or in stairwells, where reaching a traditional sash would be impractical.
Three Frame Depth Options: Available in 72, 86, or 100 mm depths, allowing buyers to match thermal performance and structural requirements to specific project tiers and budget parameters.
Double Tempered Glass: Provides safety and durability for residential and commercial applications, featuring a verified U-Factor of 0.39 to support energy code compliance discussions.
EPDM Rubber Sealing: Delivers consistent water tightness and air tightness for long-term weather performance in exterior applications, reducing the risk of air and water infiltration.
Made-to-Size Manufacturing: Accommodates project-specific rough openings and non-standard dimensions from the nominal 30 x 40 in reference, supporting flexible architectural layouts.
Extensive Color Options: Includes wood grain and PVDF finishes to support architectural design coordination across project facades and interior styling requirements.
Customizable Styles
Glass: Double tempered glass 5+27A+5 mm for WY-72/WY-100 or 5+15A+5 mm for WY-86; upgrades include argon, warm-edge spacer, Low-E, laminated, and triple glazing.
Frame: 6063-T5 aluminum profile available in 72, 86, or 100 mm frame depth options to match project performance and budget requirements.
Size: Made-to-size from nominal 30x40 in (762x1016 mm); opening panel range W450-800 mm x H600-1500 mm; final dimensions confirmed per project.
Color: Standard options include Pearl White, Quartz Gray, Starry Sky Black, and wood grain finishes; PVDF and custom colors available with upcharge.
Configuration: Single casement, awning, fixed-plus-operable composite, multi-segment, or irregular shapes; final layout depends on operation side and screen selection.
Hardware Accessories
Crank: American hand crank for WY-72 or Australian hanging hand crank for WY-86/WY-100; selection depends on series and project preference.
Lock: Multi-point switch lock seat for WY-72 or single-point switch lock seat for WY-86/WY-100; hardware brand details confirmed per project.
Limiter: Simple limiter or safety limiter options available for controlled opening; casement limiters support ventilation management and child safety.
Screen: Options include anti-theft screen, 304 stainless steel high-definition mesh, King Kong mesh, and 48-mesh high-transparency mesh; compatibility confirmed per series.
Sealing: EPDM rubber strip for weather resistance; warm-edge spacer upgrade available at itemized cost for improved thermal performance at glass edges.
