The aluminium windows 1.5 x1 5 are aluminum casement windows with an outward opening / awning configuration, suited for hotels, office buildings, and high-end residential projects.
- Multi-cavity frame structure with high-performance sealed glazing system
- Custom color matching services for project-specific design requirements
- Applications across commercial, residential, and exterior scenarios
Product Details
The aluminium casement window is constructed with a 1.8mm profile thickness and 75mm frame width in a multi-cavity frame structure paired with a high-performance sealed glazing system. The standard glass specification is double tempered glass with argon gas at 5mm+20A+5mm with a PVDF aluminum strip between the panes. The production process covers surface treatment, profile processing and cutting, glass cutting and aluminum strip installation, opening fan installation, frame and casing assembly, debugging and sealing, and packing. The window operates via outward opening or awning action with 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.
Procurement teams should confirm the glass configuration from seven available options including single, double, triple, laminated, and frosted variants with specific builds such as 5MM+27A+5MM and 5MM+12A+5MM+12A+5MM, and verify whether the standard Black Skin finish meets project requirements. Buyers should also confirm the handle style from in-house developed ergonomic lever handles with two base style options, and validate that DERCHI-developed transmission components engineered for the WY-75 profile system and the stainless steel friction hinge with multiple pivot points match the intended operational loads. Delivery is 25-35 days after deposit and drawing confirmation, and a 10-year warranty covers frame unfading and peel-off as well as hardware working properly under correct operation.
