Contemporary Multi-Bay Louvre & Fixed Window | H1225 x W1800

The H1225 x W1800 contemporary multi-bay louvre and fixed window is a premium architectural unit designed for absolute climate control and massive airflow. Measuring 1225mm high by 1800mm wide, this window combines the structural clarity of a fixed glass panel with the incredible ventilation power of adjustable louvre galleries. It is the ultimate choice for Australian coastal homes, tropical builds, and any living space where you want to capture natural cross-breezes without restricting your outside view.

The Architectural Logic of the Multi-Bay Format

Selecting the right window dimensions and styles can drastically alter how your home feels and functions. The 1225mm height is a highly specific and practical choice in Australian construction. It aligns perfectly with standard brickwork coursing. Your builder can install this unit without needing to cut bricks or manipulate the exterior cladding to make it fit. The 1800mm width is equally practical because it sits comfortably within standard timber wall framing.

The true advantage of this unit lies in the multi-bay design. We divide the 1.8-metre width into distinct vertical sections. Typically, this format features a large fixed picture pane in the centre flanked by two operable louvre bays on the outside. A traditional sliding or awning window can only ever open to roughly half of its total frame capacity. Louvre windows are entirely different. Because the individual glass blades pivot horizontally, you can open the louvre bays to nearly 100 percent capacity.

This hybrid layout gives you the absolute best of both structural worlds. You secure a large, crystal clear fixed window right in the middle of the frame where you naturally look out. On the left and right sides, you gain two massive ventilation zones. You can tilt the louvre blades slightly to catch a gentle morning breeze or open them fully to flush hot air out of your house on a sweltering summer afternoon.

Key Features and Build Specifications

We engineer our custom aluminium windows to deliver exceptional reliability. Every component is selected to ensure your home remains comfortable and secure under harsh weather conditions.

• Overall Dimensions: 1225mm exact outer frame height by 1800mm exact outer frame width.

• Frame Profile: Heavy-duty extruded aluminium designed to support multiple vertical bays without any structural deflection.

• Louvre Galleries: Premium commercial grade gallery clips hold every glass blade tightly and allow for precise angle adjustments.

• Operating Hardware: Ergonomic, colour-matched control handles provide smooth operation and lock the blades securely in the closed position.

• Weather Sealing: Integrated weather strips and tight gallery compression ensure the window blocks out wind and driving rain when fully closed.

Ideal Placements for Australian Homes

The combination of fixed glass and adjustable louvres makes this 1.8-metre wide frame incredibly versatile. Builders and homeowners specify this exact unit to solve ventilation challenges in heavily used rooms.

Open Plan Living and Dining Areas Installing this window in a main living space completely changes the room dynamics. It draws immense natural light indoors. More importantly, it acts as a massive thermal regulator. You can use the louvre galleries to catch passing winds and funnel them directly into your house. This natural cooling method heavily reduces your reliance on expensive air conditioning during the warmer months.

Alfresco Enclosures and Sunrooms If you are enclosing a patio or building a dedicated sunroom, you need maximum airflow to stop the space from feeling like a greenhouse. Installing multiple multi-bay louvre windows along the exterior wall gives you total control over the environment. You can close the blades to block cold winter winds while still enjoying the view. In summer, you open everything up to bring the outside in.

Hallways and Architectural Breezeways Long hallways often trap hot, stagnant air. Placing this window at the end of a corridor creates a highly effective breezeway. The adjustable blades pull fresh air through the centre of your home, promoting a healthy living environment and preventing condensation buildup in darker areas of the house.

Customising Your Glazing and Finish

Your glass selection plays a massive role in your daily thermal comfort. We build your windows to order so you get the exact performance you require.

Standard Clear glass is a cost effective choice for well shaded patios or southern elevations. If this window faces the harsh western sun, standard glass will trap the heat inside. We strongly recommend upgrading to Low-E glass or a Grey Tint for exposed locations. Low-E glass features a microscopic, transparent coating that actively reflects radiant heat back outside. It stops your rooms from overheating in summer and retains your interior heating during winter.

For the highest level of energy efficiency, we can configure the central fixed pane as a Double Glazed unit while matching the outer louvre blades with heavy-duty Low-E toughened glass. This provides an excellent thermal barrier in the centre of the window while maintaining the massive ventilation benefits on the sides.

We protect all our aluminium frames with a tough powder coated finish that resists chalking and coastal corrosion. Pearl White remains a classic choice for traditional builds because it actively reflects heat. Custom Black delivers a bold, high contrast frame that highlights contemporary architecture perfectly. Our Custom Colour service is available if you need to perfectly match existing window frames during a major home extension.

Internal Security and External Screening

Louvre windows pivot outward slightly, meaning all protective screens must be mounted to the exterior of the frame. Our window profiles are extruded with integrated external tracks to hold these screens securely. The screens sit far enough away from the glass to allow the blades to open fully without touching the mesh.

A standard Flyscreen keeps mosquitoes away during warm summer nights. If you want genuine security, upgrade to our Stainless Steel Security Screens. This heavy-duty woven mesh resists knife attacks and forced entry attempts. It allows you to leave your louvre blades pitched wide open on a hot night while keeping your family totally secure inside.

Frequently Asked Questions

Are louvre windows completely weatherproof? Yes. Modern louvre galleries have advanced significantly. When the control handle is pushed into the locked position, the glass blades compress tightly against one another and against the perimeter weather seals. This creates a solid barrier that effectively blocks out high winds and heavy driving rain.

Can I clean the outside of the glass from inside the house? This is one of the greatest hidden benefits of louvre windows. Because the glass blades pivot horizontally, you can easily reach through and wipe both the inside and the outside of each blade from the comfort of your living room. You do not need to climb ladders to wash the exterior glass.

What is the lead time for a custom multi-bay window? We build this unit entirely to order based on your specific colour, glass, and screen choices. Our standard manufacturing lead time is 3 to 5 weeks from the date of purchase. Our production team will keep you updated on the build progress and schedule a firm delivery date once the unit passes our final quality control checks.
