900 x 1800 aluminium window

Product Details

The 900 x 1800 aluminium window is an aluminum casement window built on the WY-75 profile system with a 1.8MM aluminum profile thickness and 75MM frame width. The opening way is outward opening or awning, and the hinge system uses a stainless steel friction hinge with multiple pivot points. Transmission components are engineered specifically for the WY-75 profile system, and the glass unit consists of double tempered glass with argon gas in a 5mm+20A+5mm configuration with a PVDF aluminum strip between the panes. A DERCHI insulation strip is integrated into the frame assembly.

Seven glass configuration options are available including single, double, triple, laminated, and frosted glass variants, with specific setups such as 5MM+27A+5MM and 5MM+12A+5MM+12A+5MM. The Black Skin finish is maintained as standard inventory color for immediate availability on standard orders. Hardware selections include a customized baseless safety handle, a customized 12-inch heavy-duty hinge, and customized lock point and lock base, all of which have passed repeated cycle tests. A 10-year product warranty covers frame unfading and peel-off as well as proper hardware and accessories operation under correct use. Confirm glass configuration, finish color, and hardware specifications before finalizing an order.

Product Features

• The WY-75 Series aluminum casement window is built for 900 x 1800 openings — specify this system when project dimensions match that size.

• A 1.8 mm profile thickness and 75 mm frame width define the structural footprint; confirm these against your rough opening and wall depth before selection.

• Outward opening and awning configurations direct the sash away from interior spaces, fitting rooms where inward swing clearance is constrained.

• Multi-cavity frame construction paired with a sealed glazing system delivers 35 dB sound insulation for buildings exposed to traffic or urban noise.

• Upgraded profile rigidity satisfies stringent wind load standards, making the window suitable for high-rise commercial and super high-rise residential buildings.

• Single sash, double sash, multi-panel, angled top, geometric, and hexagonal configurations are all available within the WY-75 system — match the style to your architectural design.

• DERCHI-developed ergonomic lever handles include two base style options; choose the base that matches your interior hardware aesthetic.

• A standard DERCHI insulation strip is included for projects requiring thermal break performance.

• The 12-inch heavy-duty stainless steel friction hinge with multiple pivot points sustains load-bearing operation on outward-opening sashes.
