Product Details
The DERCHI grey aluminium window is a casement window built with a 50MM frame width and 1.4MM profile thickness, using aluminium profiles with a PVDF aluminium strip between double tempered glass units (5mm+20A+5mm) filled with argon gas. The sash operates through outward opening or awning action on 13-inch flat open friction hinges that provide controlled opening resistance and hold sash position without additional support arms. A customized fork-type handle connects directly to a transmission mechanism, and customized transmission boxes transfer handle rotation to multiple integrated lock points and lock bases around the sash perimeter. EPDM weather seals and a silicone glass bonding process seal the frame and glazing assembly.
The WY-50 series carries a standard Black Skin finish, while PVDF coated options are available for exterior exposure. The glass system supports single glass, triple glazing, laminated glass, and frosted glass configurations beyond the standard double tempered argon unit, and custom shapes include rectangular combinations, angled tops, and geometric forms. The window is also compatible with external fly screens. Procurement teams should confirm glass configuration, custom shape, exterior finish, and fly screen compatibility against project requirements before finalizing specifications.
Customizable Styles
Color options: Black Skin finish as standard stock for the WY-50 series, or PVDF coated finish for exterior exposure.
Glass configurations: double tempered glass with argon gas (5mm+20A+5mm with PVDF aluminum strip), single glass, triple glazing, laminated glass, or frosted glass.
Opening way: outward opening or awning.
Hardware options: customized fork-type handle; 12-inch heavy-duty hinge or 13-inch flat open friction hinges; customized integrated lock point with lock base.
Exterior exposure condition determines PVDF coating selection; glass performance requirement determines single, double, triple, laminated, or frosted glass choice; opening direction preference determines outward or awning configuration.
