Arch windows are fabricated to follow a curved or arched opening head rather than a standard rectangular shape, requiring frame components formed or segmented to the exact radius of the opening — used on façades referencing traditional or classical architectural styles.

Round (porthole-style) windows are circular fixed glazing units used as a distinctive architectural feature rather than a standard opening — common on gable ends, stairwells, and feature façade elements where a strong geometric statement is wanted.

Fixed windows are sealed, non-opening glazed units used where daylight and views are wanted without the need for ventilation — stairwells, feature walls, and tall or hard-to-reach openings. Aluminium framing is engineered for structural glazing loads and weather sealing, with solar-control glass options for heat management.

Sliding windows open horizontally along a track rather than swinging outward, making them well suited to façades where a projecting sash isn’t practical. Multi-track aluminium frames, weatherstripping, and roller hardware are specified for smooth, long-term operation.

Skylights and roof glazing systems bring natural daylight deep into a building’s interior, reducing reliance on artificial lighting. Aluminium framing supports large glazed spans while managing structural loads, drainage, and thermal performance, with solar-control or low-E glass options to limit heat gain in sunny climates.
