Product Overview

Aluminum Bay Window – Expand Your Space, Elevate Your View

An aluminum bay window is one of the most architecturally impactful fenestration upgrades available to homeowners, builders, and designers. By projecting outward from the main building envelope at a defined angle, the bay window creates additional floor space inside the room, floods the interior with natural light from three directions simultaneously, and transforms an otherwise flat wall into a distinctive architectural feature that enhances both the building's exterior character and interior livability. SKATE's aluminum bay windows combine reinforced aluminium corner connectors, premium thermal break profiles, and precision-engineered corner angles to deliver a system that is as structurally robust as it is visually spectacular.

Configuration Options

SKATE aluminum bay windows are available in the three most common architectural configurations:

- Box Bay (90° corners): Squared projection with a flat front panel and two 90° side panels returning to the main wall. Maximises interior space gain. - Angled Bay (135° corners): The classic three-panel bay with angled side wings creating a gentler projection. Most widely used in traditional residential architecture. - Bow Window: A curved or polygonal assembly of multiple narrow panels creating a smooth, rounded projection. Typically four to seven panels. Suits period and formal architectural styles.

Corner angles can also be specified at custom angles between 90° and 150° to match existing building geometry or unique design requirements.
