The 42 x 36 casement window is a DERCHI made-to-size thermal break aluminum window built around the 42 x 36 inch (1067 x 914mm) opening size. Rather than a stock catalog item, each unit is configured to project requirements across three series tiers — R8Y for safety and coastal performance, E0 for value-driven batch projects, and S6 for lightweight project applications. The recommended double-sash structure divides the opening into two sashes of approximately 21 inches each, falling within the common outward-opening sash width range.
- Made-to-size, not a standard stock window
- Three series options covering premium, value, and lightweight segments
- Double-sash recommended structure with each sash ~21in / 533mm
- Outward-opening glass sash with inward-opening screen sash
Product Details
At 42 x 36 inches (1067 x 914mm), the total window area measures approximately 0.98 square meters. As a custom 42 x 36 casement window, the recommended double-sash configuration splits this into two sashes of roughly 21.0 inches (533mm) each — well within the 350–750mm opening sash width range. A three-lite alternative would yield 14.0-inch (356mm) lites. The glass sash opens outward while the screen sash operates inward, allowing ventilation without compromising insect protection. For larger wall openings, the system supports fixed-plus-opening combinations with maximum single fixed glass up to 12 square meters.
The main recommended R8Y Ruixuan series carries a 118mm frame width, 1.8mm wall thickness, and 35/34/16mm thermal break strips in a safety-oriented outward-opening system. E0 Glory offers a 100mm frame for budget-conscious batch residential work, while S6 Xinghai uses an 82mm frame with an invisible folding screen for lightweight project windows. All three series share identical performance ratings: 700Pa water tightness (Class 6), 5kPa wind pressure resistance (Class 9), and 35dB sound insulation (Class 4). Buyers should confirm which series matches their project budget, performance, and screen requirements before requesting a quote.
Product Features
- Three-Seal Weather System: R8Y uses a three-seal configuration with equal-pressure and concealed drainage channels plus EPDM water-swelling weatherstrip, managing heavy rain and wind-driven moisture in coastal installations.
- 35mm Thermal Break Strip: The super-wide polyamide strip separates interior and exterior aluminum profiles, reducing heat transfer and supporting the 2.0W Class 6 thermal insulation rating across all three series.
- Anti-Fall Safety Rope: A 150KG-bearing rope prevents sash drop in high-rise outward-opening applications, adding a physical safeguard where wind gusts could stress the hinge mechanism.
- WEHAG Antibacterial Handle: Silver ion coating on the WEHAG handle inhibits up to 99% of bacterial growth, addressing hygiene concerns in residential, hospitality, and healthcare-adjacent environments.
- Four-Sided Six-Point Lock: This invention-patented black zinc alloy lock engages multiple points around the sash perimeter, improving security and compression sealing against air and water infiltration.
- Diamond Mesh Screen System: Built-in diamond mesh pressure bead with anti-theft flyscreen and anti-collision corner protector integrates insect screening and physical security into the window frame.
Customizable Styles
- Glass Configuration: Standard 5+27A+5 insulating tempered glass with fluorocarbon aluminum spacer; optional argon gas, Low-E, laminated, frosted, tinted, ultra-clear, or blind glass per project needs.
- Frame and Series Selection: R8Y (118mm), E0 (100mm), or S6 (82mm) thermal break aluminum profiles at 1.8mm wall thickness — confirm profile depth per structural and budget requirements.
- Size and Sash Division: Base 42x36in opening with double-sash, three-lite, fixed-plus-opening, or multi-lite combinations; provide project drawings for custom layouts beyond standard divisions.
- Color and Finish: Twelve R8Y colors including Sand Gray, Black Walnut, and White; eight additional E5N card colors; finishes in powder coating, fluorocarbon, wood grain, or metallic flash silver.
- Opening Type: Outward-opening, top-hung, or outward-opening top-hung configurations; glass sash opens outward with screen sash operating inward across all series.
Hardware Accessories
- WEHAG Baseless Handle: Ergonomic handle tested to 100,000+ open-close cycles; antibacterial version with silver ion coating available for hygiene-sensitive environments.
- 12-Inch Friction Hinge: Controls sash movement during outward opening, holding position at various angles to reduce wind-slam damage in exposed installations.
- Four-Sided Six-Point Lock: Custom black zinc alloy invention-patented lock engaging perimeter points for security and uniform compression sealing.
- Anti-Fall Rope: 150KG bearing capacity safety rope prevents accidental sash detachment in high-rise outward-opening applications.
- Diamond Mesh and Sealing Hardware: Built-in diamond mesh pressure bead with anti-theft flyscreen; EPDM water-swelling weatherstrip and three-seal system manage water and air infiltration.

- Coastal Weather Performance: Three-seal system with equal-pressure drainage, concealed drainage, and EPDM water-swelling weatherstrip manages heavy rain and wind-driven moisture in typhoon-exposed zones.
- Multi-Tier Series Strategy: R8Y, E0, and S6 cover premium safety, value batch, and lightweight project segments — all sharing 5kPa wind resistance and 700Pa water tightness ratings.
- Made-to-Size Flexibility: Over fifteen structure combinations, twelve-plus colors, and multiple glass options let buyers match specific project drawings without compromising thermal break performance.
- Export-Ready Packaging: Four-layer protection with anti-scratch film, pearl cotton, waterproof outer film, and fully enclosed wooden rack supports safe international shipping to port or door.
Application Scenarios
- Apartment: The 42x36 opening fits standard apartment bedroom and living room dimensions. Double-sash configuration provides cross-ventilation while the inward screen sash allows cleaning access from inside, suiting multi-unit residential builds.
- Home Office: Natural light and operable ventilation support comfortable work-from-home environments. Top-hung opening directs airflow upward without desk-level drafts, and the anti-theft flyscreen adds security during occupied hours.
- Hotel: Hospitality projects benefit from the WEHAG antibacterial handle and 35dB sound insulation. The outward-opening sash preserves interior floor space while maintaining guestroom ventilation and acoustic comfort against street noise.
- Office Building: Commercial 42 x 36 casement window installations can integrate this size within fixed-plus-opening or multi-lite window-wall combinations. The 5kPa wind pressure rating supports mid-to-high-rise applications; confirm local code compliance for specific elevation zones.
- Outdoor: For semi-exposed corridors or sheltered outdoor spaces, buyers should confirm water tightness performance under specific exposure conditions and verify that the selected surface finish resists UV and moisture over the intended service life.
- Residential Building: Batch residential developments can leverage E0 series for cost-efficient thermal break double glazing across repeated openings. Common MOQ of approximately 2 square meters may apply; confirm per project volume with supplier.
- Exterior: Exterior wall installations require verified wind pressure, water tightness, and thermal performance. Confirm that the selected series, glass configuration, and installation method meet local building code and energy compliance for the target climate zone.
- Villa: Custom villa projects can specify R8Y with colors like Black Walnut or Fluorocarbon Flash Silver, paired with Low-E or laminated glass. The 35mm thermal break strip supports energy-efficient comfort in larger residential homes.
