- Double tempered glass: 5+27A+5 mm (WY-72/WY-100) or 5+15A+5 mm (WY-86)
- Made-to-size within opening panel range W450-800 mm x H600-1500 mm
Product Details
The 30x30 casement window uses a 6063-T5 aluminum profile with 1.4 mm wall thickness and EPDM rubber strip sealing. Double tempered glass comes in two configurations — 5+27A+5 mm for WY-72 and WY-100, or 5+15A+5 mm for WY-86. Unlike push-out casement windows, this crank-out window uses a geared hand-crank operator to set a precise opening angle without reaching outside.
Three frame depth series — 72, 86, and 100 mm — let teams match performance targets and hardware to local standards. WY-72 pairs with American-style crank and multi-point lock; WY-86 and WY-100 use Australian hanging crank with single-point locking. The nominal 30 x 30 inch size (762 x 762 mm, ~0.58 m²) fits compact residential openings, while the broader panel range supports non-standard dimensions.
Product Features
Hand-Crank Operation: The geared crank mechanism opens and positions the sash from inside the room, useful for upper-floor or hard-to-reach installations where reaching outward is impractical.
Double Tempered Glass: Two tempered panes with configurable spacer widths (27A or 15A) provide safety glazing and baseline thermal performance; this double tempered glass window configuration supports different series targets.
6063-T5 Aluminum Frame: The 1.4 mm profile thickness offers structural integrity for standard residential wind load conditions, giving the hand crank aluminum window reliable everyday operation.
EPDM Rubber Strip Sealing: Continuous EPDM sealing at frame joints helps limit air infiltration and water penetration, contributing to consistent weather performance under standard environmental exposure conditions.
Three Frame Depth Options: Series 72, 86, and 100 mm allow buyers to select frame depth based on project performance requirements, glass configuration, and regional hardware preferences.
Made-to-Size Production: The opening panel range of W450-800 mm x H600-1500 mm supports project-specific dimensions, enabling this made-to-size casement window to go beyond nominal 30 x 30 inches.
Customizable Styles
Opening Configuration: Choose single casement, awning, or fixed-plus-operable composite layouts based on ventilation needs and installation position for each project.
Size Customization: Within the opening panel range of W450-800 mm x H600-1500 mm, this aluminum casement window can be produced to project-specific dimensions.
Color Selection: Twelve official color families include Pearl White, Quartz Gray, Starry Sky Black, Deep Coffee, Black Walnut wood grain, and Mint Gold.
Glass Upgrades: Low-E, argon-filled, warm-edge spacer, laminated, and triple glazing options adjust U-Factor, SHGC, and acoustic performance for project targets.
Screen and Safety: Anti-theft screen, 304 mesh, King Kong mesh, 48-mesh mesh, and fixed or opening safety fence — confirm series compatibility with DERCHI.
Hardware Accessories
American Hand Crank (WY-72): Paired with a multi-point switch lock seat, this crank set provides secure operation and multi-point locking for flat-opening configurations.
Australian Hanging Hand Crank (WY-86/WY-100): Combined with a single-point switch lock seat, this hardware supports top-hung operation for projects requiring different opening mechanics.
Casement Limiters: Simple limiters and safety limiters are available as optional add-ons to control opening angle and improve child safety on elevated installations.
Screen Mesh Options: 304 stainless steel mesh, King Kong mesh, and 48-mesh high-transparency mesh provide insect protection while allowing airflow — confirm series compatibility.
Safety Fence: Fixed or opening safety fence options add a physical barrier for elevated installations and child-safety-sensitive applications — selection depends on project requirements.
