    Bay & Corner Double Glazed Windows for Light, Comfort & Performance

    Corner & Bay Windows Melbourne. More Light. More Space. More Wow.

    Bay windows don’t just sit in a wall. They extend beyond it. That’s what makes them special. Three or more windows angled outward from your exterior wall, flooding your room with natural light and creating space that didn’t exist before.

    What Makes Bay Windows Different From Every Other Window?

    The Ordinary:

    • Most windows sit flat in a wall
    • One angle. One view. One source of light.
    • An ordinary flat window does the basics. Nothing more.

    The Bay:

    • Bay windows extend outward from your exterior wall at angles
    • Three or more windows joined together to create a panoramic view
    • Light pours in from multiple directions. The room feels bigger. The street looks better.
    • They create space inside your home that wasn’t there before. A window seat. A reading nook. A desk. Storage. Whatever you want.

    Traditional vs Modern vs Curved:

    • Traditional bay windows project outward at set angles, commonly 30, 45, or 90 degrees, from the facade. Classic architecture. Period homes. Timeless curb appeal.
    • Modern bay windows use clean lines and slim uPVC profiles for a contemporary look. Sharp angles. Minimal frame. Maximum glass.
    • Curved bay windows, also called bow windows, use a series of windows set at gentle angles to form a smooth, curved shape. Elegant. Distinctive. A real feature.
    • Corner windows wrap around inside corners of a building, turning dead space into a light-filled feature.
    • Oriel windows are bay windows that don’t touch the ground. They project from an upper floor, supported by brackets or corbels.

    A Panoramic View From Inside Your Home.

    Curb Appeal That Turns Heads.

    • A bay window changes the entire facade of your house
    • From the street, it adds shape, depth, and architectural character

    Where Do Bay Windows Work Best?

    • Living rooms — The classic choice. A bay window creates a focal point, a seating area, and floods the room with natural light. Most bay windows in Australian homes are installed here.
    • Bedrooms — Wake up to a panoramic view. Add a window seat or reading nook. Bay windows make bedrooms feel like a retreat.
    • Kitchens — A bay window above the bench turns dishwashing into something you don’t mind. Extra light. Extra ventilation. Extra bench space.
    • Home offices — Put your desk in the bay. Natural light from three angles. Views to break up the screen time. Productivity goes up.
    • Front-facing rooms — Bay windows add instant curb appeal to your facade. They tell the street your house has character.
    • Period homes and renovations — Replacing old aluminium windows with double glazed uPVC bay windows is one of the smartest upgrades for an existing home. Better insulation. Better security. Better everything.

    Frequently Asked Questions (FAQs)

    1. What exactly is a bay window?

    A bay window is a window structure made up of three or more windows that extend outward from the exterior wall of a house. They project beyond the facade at set angles, creating additional space inside the room and allowing natural light to enter from multiple directions. Bay windows can improve airflow compared to standard fixed picture windows when side windows are operable. Most bay windows include a combination of fixed windows in the centre with operable casement windows or awning windows on the sides for ventilation.

    Bay windows became widespread in America during the California Gold Rush, reflecting their growing popularity in architectural design during the 19th century.

    Bay windows come in several configurations, including box bay windows, canted bay windows, and circle bay windows, each tailored to different architectural requirements and visual preferences. Box bay windows project straight out from the wall and form a rectangular shape, making them popular in contemporary homes for their clean lines and additional floor space. Canted bay windows, commonly seen in Victorian architecture, feature a central flat window with two angled side windows, forming a polygonal shape that adds traditional charm to facades.

    2. What’s the difference between bay windows and bow windows?

    Bay windows typically use three panels at defined angles, 30, 45, or 90 degrees. Circle bay windows, also known as bow windows, consist of multiple glass panels arranged in a gentle curve, providing expansive views and a distinctive architectural statement. Both extend outward from the wall, but bow windows create a softer, more rounded projection. Circle bay windows are a variation of the bow style with a more pronounced curve.

    3. How much do bay windows cost?

    Bay windows cost will vary depending on the size, number of panels, style, glass configuration, and installation requirements of your project. Because bay windows involve more glass, more frame material, and more complex installation than a standard flat window, they are a larger investment. Replacing a bay window typically costs between $500 and $1500, influenced by factors such as size, shape, and material. Contact us for a free quote tailored to your property.

    4. Can bay windows be installed in an existing home?

    Yes. Bay windows can be installed as part of renovations or as a replacement for existing windows. The installation process will depend on the wall structure and whether additional support is needed. APS handles the full bay window installation including measurement, structural assessment, manufacturing, and fitting.

    5. Are bay windows energy efficient?

    Yes. When built with double glazing and uPVC frames, bay windows provide excellent energy efficiency. The insulated glass units reduce heat transfer, keeping your home warmer in winter and cooler in the summer months. Argon gas fill and LowE coatings come standard with every APS bay window.

    6. Do bay windows help with noise reduction?

    Yes. Double glazed bay windows significantly reduce outside noise. The two panes of glass with an insulating gap between them create an effective sound barrier. Acoustic glass upgrades are available for homes near busy roads, flight paths, or high-density areas.

    7. What styles of bay window are available?

    APS offers traditional bay windows, modern bay windows, curved bay windows, bow windows, and corner windows. Each style is custom designed and available in a range of configurations, colours, and glazing options.

    8. Are bay windows secure?

    Absolutely. Every opening panel features German engineered multi point locking systems. Glass options include toughened and laminated safety glass. All APS bay windows are internally glazed, meaning the glass cannot be removed from the outside.

    9. Do bay windows need a lot of maintenance?

    No. uPVC bay windows are low maintenance. The frames don’t need painting, sanding, or sealing. They resist corrosion, fading, and UV damage. Just wipe clean with soapy water. They’re built to last decades without losing performance or appearance.

    Timber bay windows should be finished with high-quality exterior-grade paint or sealant to protect against moisture and pests. Aluminium bay windows with powder-coated finishes should be cleaned using pH-neutral solutions to preserve their colour and finish.

    10. Can I add a window seat to my bay window?

    Yes. The additional space created by a bay window is perfect for a built-in window seat, a seating area, a desk, or storage. Many homeowners design the bay specifically with seating or storage in mind. We can advise on the best configurations to suit your room and your lifestyle.
