Aluminum Bay Window

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 aluminum 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. Maximizes 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.

Structural Engineering

Corner connectors are the most structurally critical element of any aluminum bay window. SKATE uses heavy-duty die-cast aluminum or galvanised steel corner connector plates, precision-CNC-machined to the specified angle and bolted into both the head and sill frames. This creates a rigid, triangulated structure that resists wind loading, roof loading (where a flat bay roof is specified), and long-term thermal movement. Seamless welding of all four corners on each individual window panel ensures there are no water ingress points at any joint.

The sill beneath an aluminum bay window is typically a thermally-broken aluminum cill with integral drainage, preventing water accumulation and potential structural damage to the supporting structure below.

Glazing & Thermal Performance

Each panel within the aluminum bay window can be specified as fixed, casement, tilt-and-turn, or sliding, depending on ventilation requirements and design preferences. All operable panels use the same hardware and glazing specifications as SKATE's individual window products. Thermal performance across the entire assembly is consistent, with the PA66 GF25 thermal break system and Low-E argon glazing maintaining U-values well within current energy code requirements.

For locations subject to severe weather, laminated safety glass is recommended for all panels — providing both enhanced wind resistance and protection against accidental breakage.

Aesthetics & Finishes

SKATE aluminum bay windows are available in the complete range of RAL powder coat colors, anodised finishes, PVDF coatings, and wood grain transfer printing. The angular corner sections are finished to match the main frame profiles exactly, ensuring a seamless appearance across the entire bay assembly. Decorative Georgian bars and astragal dividers can be incorporated into any panel for a traditional multi-pane aesthetic.

Ideal Applications

Aluminum bay windows are a valued addition to: living rooms and dining rooms in residential new builds and renovations; front-facing ground floor applications that benefit from the projection's curb appeal; bedroom alcoves and reading nooks; hospitality and commercial reception areas; and period renovation projects where the bay window is an existing architectural feature requiring like-for-like replacement in a modern material.
