Louvre / Louvre Window | H665 x W1800

The H665 x W1800 double-bay aluminium louvre window is an expansive horizontal architectural window engineered for wide kitchen splashbacks, servery zones, and high-level wall ventilation. Measuring 665mm high by 1800mm wide, this profile features two side-by-side louvre bays (Louvre / Louvre) within a single reinforced commercial aluminium outer frame. This dual-gallery configuration gives Australian homeowners and builders independent airflow control across a wide 1800mm span, delivering maximum natural ventilation and natural light without sacrificing structural strength or ground-floor security.

Ideal Applications for Australian Homes

A 665mm high by 1800mm wide double-bay louvre is one of the most effective window configurations for modern Australian kitchens. Its low 665mm height fits perfectly between standard kitchen benchtops and overhead cupboards, while the generous 1800mm width spans the length of a primary preparation area or sink. By placing a double-bay louvre along your kitchen splashback, you create a panoramic window that exhausts cooking heat and steam rapidly.

Having two separate louvre bays provides a major practical advantage for daily airflow control. On windy coastal afternoons, you can leave one bay closed to protect indoor cooking burners while tilting the opposite bay open to bring fresh air into the home. Because louvre blades rotate on a horizontal axis, they open to a full 90-degree angle without swinging inward over your benchtop or outward into your patio walkway.

This wide horizontal dimension is also popular for high-wall installations in living rooms, dining rooms, and bedrooms. Since warm air naturally rises toward the ceiling, placing a 1800mm wide louvre window near the top of a wall creates a high-volume thermal exit point during hot summer months. This high-level placement protects ground-floor privacy and leaves lower walls completely clear for bedheads, furniture, and entertainment units.

Configuration Guidance: Customising Your Window

When ordering your H665 x W1800 double-bay louvre window online, step through our custom configuration options to suit your room orientation and practical requirements:

1. Selecting Your Colour: Pearl White remains a popular choice for bright kitchens and traditional brick homes, reflecting intense summer sun. Custom Black creates a sharp industrial frame that looks stunning against tiled splashbacks, timber decking, and polished concrete. If your project requires an exact match to existing steelwork or roofing profiles, our Custom Colour service ensures an accurate finish.

2. Choosing Your Glass: Selecting the right glass depends on where the window is installed. For kitchen splashbacks that face west and catch harsh afternoon glare, Low-E glass or Grey Tint reduces solar heat gain while keeping preparation zones bright. If the window is installed high on a bathroom or bedroom wall facing a neighbouring property, Satinlite Obscure glass lets daylight brighten the room while keeping outside eyes out.

3. Picking the Right Screen: Kitchens and bedrooms require dependable insect protection. Standard flyscreens keep mosquitoes and flies out while you leave your double-bay louvres open for everyday cooling. For ground-floor installations where security is a priority, upgrading to a Stainless Steel Security Screen lets you leave both bays open overnight while maintaining a reinforced physical barrier against intruders.

Australian Standards, Engineering & Quality Guarantee

Every H665 x W1800 double-bay louvre window from New Age Construction Group is manufactured to meet AS 2047, the mandatory Australian Standard for windows and external glazed doors. Wide 1800mm spans require exact gallery alignment and central structural mullion support to prevent blade rattling 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 requiring reliable site delivery or a homeowner managing a major kitchen 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 is an 1800mm wide louvre window split into two bays? Individual glass louvre blades have a maximum safe span to prevent bending and rattling in high winds. By splitting an 1800mm wide frame into two side-by-side bays (Louvre / Louvre) with a reinforced central mullion, the window complies with Australian Standards while giving you independent airflow control for each side.

Can I install external screens across a double-bay louvre window? Yes. Our double-bay louvre windows are built with a continuous external screen recess that fits standard flyscreens, Diamond Grille, or Stainless Steel Security Screens. The screens sit securely on the outside of the frame without interfering with the rotation of either louvre bay.

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.
