BIEYE’s product range is deliberately focused. Rather than offering every window and door type, the company concentrates on four aluminum systems that cover the majority of residential and light commercial project requirements: casement windows, awning windows, casement doors, and French doors.

Here is what each system is, where it gets specified, and what makes the BIEYE version worth looking at.

Casement windows

A casement window is hinged on one side and opens outward. It is the most widely specified residential window type globally, and for good reason — it provides full-panel ventilation, a clean sight line, and straightforward operation.

BIEYE’s casement windows use German multi-point locking hardware, which compresses the sash against the weatherseal at multiple points when closed. This matters for both weather performance and security. Single, double, and triple glazing options are available, and low-E glass can be specified for markets with energy code requirements.

These windows go to Australia regularly, where wind resistance ratings are tested, and to Southeast Asian markets where the priority is ventilation in a climate that is hot and wet most of the year.

Awning windows

Hinged at the top and opening outward from the bottom, the awning window solves something a casement cannot: you can leave it open in the rain. The open sash acts as a canopy, so air comes in while water stays out.

This makes awning windows a practical choice for bathrooms, kitchens, and upper-floor openings in tropical climates — which is exactly where BIEYE sells them. The friction-stay hinge holds the sash at any opening angle, and the multi-point lock closes it securely.

Casement doors

Heavy-duty extruded aluminum profiles, reinforced corner joints, German hardware rated for the weight and frequency of use. BIEYE’s casement doors are built for entrances that get used — residential front doors, commercial building entries, internal courtyard access.

Threshold options include standard and low-profile variants. The low-profile threshold is relevant for Australian and US projects where accessibility requirements apply. Powder coat finishes to standard or custom RAL colors.

French doors

Two leaves, full-height glazing, opening outward or inward. French doors are specified when the goal is maximum light and a visual connection between interior and exterior — terraces, garden access, balconies.

Aluminum’s slim profiles give more glass area than timber or PVC for the same opening size. BIEYE’s French doors have internal reinforcement sections within the extruded frame to maintain structural rigidity without adding visible bulk. Multi-point locking on both leaves. Thermal break option available for colder climates.

Custom configurations

Standard products cover most project requirements. When they do not — shaped openings, non-standard dimensions, combined systems like a French door with fixed sidelights or awning transoms — BIEYE’s engineering team works from project drawings to produce shop drawings before fabrication begins.
