Fixed Louvre Combo | H1225 x W1800

The H1225 x W1800 fixed-louvre combo window is a wide-span architectural glazing solution engineered to deliver expansive natural daylight alongside high-volume adjustable ventilation. Measuring 1225mm high by 1800mm wide, this generous profile integrates a large fixed central or side glass panel with operable louvre bays within a single, heavy-duty commercial aluminium outer frame. This hybrid design gives Australian homeowners the ideal balance of unobstructed outdoor views and steady daylight on one side, paired with precise, controllable airflow on the other, all without compromising structural wind ratings or home security.

Ideal Applications for Australian Homes

A 1225mm high by 1800mm wide fixed-louvre combo window is one of the most practical wide-span glazing configurations for modern residential construction. Its balanced height and generous 1.8-metre width fit standard timber-frame and brick-veneer wall openings, making it a standout choice for master bedrooms, open-plan living areas, dining zones, and home extensions where you need both permanent picture views and targeted cross-ventilation.

In spaces like a master bedroom or family living room, a standard sliding window forces you to compromise between a clear view and active airflow. With a wide fixed-louvre combo window, the fixed glass panel acts as a broad picture window that frames your outdoor garden or streetscape permanently, while the operable louvre bays beside it can be tilted open to capture refreshing breezes. Because louvre blades rotate on a horizontal axis, you can direct airflow upward toward the ceiling, avoiding strong draughts across furniture and living spaces.

For coastal properties across Sydney, Newcastle, and regional New South Wales, the marine-grade aluminium frame handles salty air effortlessly while giving you flexible climate control year-round.

Configuration Guidance: Customising Your Window

When ordering your H1225 x W1800 fixed-louvre combo window online, step through our custom configuration options to suit your room layout and environmental needs:

1. Selecting Your Colour: Pearl White remains a practical choice for classic weatherboard homes and brick facades, reflecting intense summer sun. Custom Black creates a sharp, modern industrial outline that pairs well with timber decking, matte black hardware, and polished concrete. 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 and solar exposure. For north or west-facing living areas that catch harsh afternoon sun, Low-E glass or Grey Tint reduces solar heat gain and glare while keeping interiors bright. If the combo window is installed in a room facing a boundary fence, Satinlite Obscure glass lets natural daylight brighten the space 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 louvre bays open for overnight cooling. For ground-floor installations where security is a priority, upgrading to Stainless Steel Security Screens lets you leave the ventilation bays tilted open safely while maintaining a reinforced steel barrier against intruders.

Australian Standards, Engineering & Quality Guarantee

Every H1225 x W1800 fixed-louvre combo window from New Age Construction Group is manufactured to comply with AS 2047, the mandatory Australian Standard for windows and external glazed doors. Combining wide fixed glazing and operable galleries across an 1800mm span requires exact structural alignment and mullion support to prevent glass stress, frame twisting, and wind deflection. This is why our frames undergo rigorous testing for structural deflection, operating force, air infiltration, and water penetration resistance.

Manufactured at our Smeaton Grange facility in New South Wales, our windows are built using commercial-grade aluminium and quality hardware engineered for Australian weather conditions. Whether you are a trade builder ordering for a residential development or a homeowner managing a major 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

What is the advantage of a wide fixed-louvre combo window over a standard sliding window? A fixed-louvre combo window gives you permanent, unobstructed views through the wide fixed glass panel while allowing you to control high-volume cross-ventilation through the operable louvre sections. Standard sliding windows only open across half of their width and require moving sashes that can obstruct indoor curtains or furniture.

Can I choose the layout configuration for the fixed and louvre sections? Yes. When configuring your window online or through our trade team, you can specify your preferred layout (such as a central fixed panel flanked by louvre bays, or a side-by-side split) to match your interior room design and furniture placement.

What is the standard manufacturing lead time for custom combo 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.
