Louvre / Louvre Window | H1225 x W1200

The H1225 x W1200 double-bay aluminium louvre window is a versatile mid-sized architectural window engineered for residential bedrooms, home offices, and living rooms across Australia. Measuring 1225mm high by 1200mm wide, this profile features two side-by-side louvre bays within a single commercial-grade aluminium frame. This dual-gallery design gives homeowners independent airflow control across a standard 1200mm wall opening, delivering excellent cross-ventilation, expansive outdoor views, and reliable ground-floor security without compromising on weatherproofing.

Key Features & Technical Specifications

• Dimensions & Bay Layout: Exactly 1225mm in height and 1200mm in width, configured as a double-bay louvre window with two independent operating banks of horizontal glass blades.

• Frame Profile & Strength: Built from heavy-duty commercial extruded aluminium, engineered with a central structural mullion to prevent frame deflection, twisting, and rattling under harsh Australian wind loads.

• Glass & Blade Options: Configurable with 102mm or 152mm glass blades in Clear, Grey Tint, Low-E thermal glass, Satinlite Obscure for privacy, and double-glazed variants for superior climate insulation.

• Hardware & Locking Mechanism: Equipped with dual mechanical blade galleries and key-lockable handles, allowing you to operate each bay independently and clamp the glass blades shut securely.

• Weather & Energy Performance: Built with perimeter dual-seal weather stripping and interlocking blade closure to prevent air draughts and water penetration, helping your property achieve strong WERS compliance.

Ideal Applications for Australian Homes

A 1225mm high by 1200mm wide double-bay louvre is one of the most practical window dimensions in Australian residential construction. Its balanced, square-like proportion fits comfortably into standard brick-veneer and timber-framed walls, making it a popular choice for primary bedrooms, guest rooms, and dedicated home offices. Where traditional sliding windows only allow half of the window area to open at any time, a double-bay louvre window gives you 100 percent ventilation capacity across the entire 1200mm width.

Having two separate louvre bays provides a major practical advantage for daily airflow control. On cool or windy afternoons, you can leave one bay closed to prevent papers from blowing around your study desk while tilting the opposite bay open to draw fresh air into the room. Because the blades open horizontally, you can regulate ventilation precisely without creating strong floor-level draughts.

This mid-sized dimension also works brilliantly in living and dining rooms that require both natural light and high-volume airflow. For coastal builds across Sydney, Newcastle, and regional New South Wales, the marine-grade aluminium frame handles salty sea air effortlessly while capturing refreshing afternoon sea breezes.

Configuration Guidance: Customising Your Window

When ordering your H1225 x W1200 double-bay louvre window online, step through our custom configuration options to suit your room layout and environmental needs:

1. Selecting Your Colour: Pearl White suits traditional brickwork and classic weatherboard homes while reflecting harsh summer sun. Custom Black creates a sharp, modern industrial outline that pairs well with timber decking, matte black door hardware, and polished concrete floors. If your project requires an exact match to existing window frames, our Custom Colour service ensures a precise result.

2. Choosing Your Glass: Selecting the right glass depends on room orientation. For north or west-facing bedrooms that receive intense afternoon sunlight, Low-E glass or Grey Tint reduces solar heat gain and protects interior furnishings from UV fading. If the window faces a boundary fence or neighbouring property, Satinlite Obscure glass lets natural daylight brighten the room while protecting your personal privacy.

3. Picking the Right Screen: Bedrooms and living spaces require dependable insect protection during warm Australian evenings. Standard flyscreens keep mosquitoes and flies out while you leave your double-bay louvres open for overnight cooling. For ground-floor installations where security is a top priority, upgrading to a Stainless Steel Security Screen lets you leave both bays open safely while maintaining a reinforced steel barrier against intruders.

Australian Standards, Engineering & Quality Guarantee

Every H1225 x W1200 double-bay louvre window from New Age Construction Group is manufactured to comply with AS 2047, the mandatory Australian Standard for windows and external glazed doors. Wide 1200mm spans require exact gallery alignment and central structural mullion support to prevent blade rattling and wind deflection. This is why our frames undergo strict testing for structural deflection, operating force, air infiltration, and water penetration resistance.

Whether you are a trade builder ordering for a residential development or a homeowner managing a bedroom extension, our windows arrive fully assembled and ready for installation. Standard lead times run between 12 to 15 working days to accommodate custom powder coating, precision blade cutting, and quality control prior to Australia-wide dispatch.

Frequently Asked Questions

Why choose a double-bay louvre window for a bedroom or study? A double-bay louvre window allows you to open 100 percent of the window area for maximum fresh air, compared to standard sliding windows that only open half way. Having two independent bays also lets you open one side while keeping the other closed, giving you complete control over airflow and draughts.

Can I clean the outside glass blades from inside my house? Yes. One of the biggest practical benefits of a louvre window is that you can tilt the blades to a horizontal angle and wipe both the interior and exterior glass surfaces easily from inside your home. This makes cleaning second-storey bedroom windows safe and straightforward.

What is the standard manufacturing lead time for custom louvre windows? Custom aluminium windows from New Age Construction Group typically require a manufacturing lead time of 12 to 15 working days. This allows sufficient time for custom powder coating, glass sizing, and thorough quality inspection before shipping anywhere in Australia.
