Fixed Louvre Combo | H1225 x W1200

The H1225 x W1200 fixed-louvre combo window is a hybrid architectural glazing solution engineered to combine permanent natural daylighting with controllable, high-volume ventilation. Measuring 1225mm high by 1200mm wide, this profile integrates a fixed glass panel with an operable louvre bay within a single, high-performance commercial aluminium outer frame. This clever configuration gives Australian homeowners the best of both worlds: unobstructed glass views and steady structural daylight on one side, paired with 100 percent adjustable airflow on the other, all without compromising weatherproofing or home security.

Ideal Applications for Australian Homes

A 1225mm high by 1200mm wide fixed-louvre combo window is one of the most practical hybrid configurations for modern residential construction. Its balanced, mid-sized proportion fits standard timber-frame and brick-veneer wall openings, making it a popular choice for bedrooms, home offices, bathrooms, and stairwells where you need both permanent daylight and targeted ventilation.

In spaces like a home office or guest bedroom, a standard sliding window forces you to choose between keeping the whole window closed or sliding open half of your glass view. With a fixed-louvre combo window, the fixed panel acts as a clean picture window that frames your outdoor garden or streetscape permanently, while the operable louvre bay beside it can be tilted open to catch refreshing breezes without exposing your entire window opening to the elements. Because louvre blades rotate on a horizontal axis, you can regulate airflow upward toward the ceiling, avoiding strong draughts across desks or bedding.

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 W1200 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 privacy requirements. For north or west-facing bedrooms and offices that catch harsh afternoon sun, Low-E glass or Grey Tint reduces solar heat gain and glare. If the combo window is installed in a bathroom or stairwell facing a boundary fence, 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 louvre bay open for overnight cooling. For ground-floor installations where security is a priority, upgrading to a Stainless Steel Security Screen lets you leave the ventilation bay tilted open safely while maintaining a reinforced steel barrier against intruders.

Australian Standards, Engineering & Quality Guarantee

Every H1225 x W1200 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 fixed glazing and operable galleries within a single outer frame requires exact structural alignment 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 an 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 fixed-louvre combo window over a standard sliding window? A fixed-louvre combo window gives you permanent, unobstructed views through the fixed glass panel while allowing you to control high-volume cross-ventilation through the operable louvre bay. Standard sliding windows only open across half of their width and require moving sashes that can obstruct curtains or indoor furniture.

Can I choose which side the operable louvre bay is on? Yes. When configuring your window online or through our trade team, you can specify whether you prefer the operable louvre section on the left or the right side to match your interior room layout 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.
