Our most popular window style. Sliding windows operate on a horizontal track, making them easy to open and close. They provide excellent ventilation, are easy to clean from inside, and are ideal for rooms facing walkways or patios where outward-opening windows would be impractical.
Casement Windows
Casement windows are hinged on one side and open outward like a door, operated by a crank handle or friction stay. They offer maximum airflow as the entire window opening is unobstructed. Perfect for capturing breezes and providing clear, uninterrupted views.
Awning Windows
Awning windows are hinged at the top and open outward from the bottom. This clever design allows you to leave them open during light rain while still providing ventilation. They are the ideal choice for wet areas such as bathrooms, laundries, and kitchens.
Fixed Windows
Fixed windows do not open — they are designed purely to let light in and provide views. They offer the best thermal and acoustic insulation of any window type because there are no moving parts or seals that can leak. Ideal for feature windows, highlight windows, and areas where ventilation is not needed.
French Casement Windows
French casement windows feature two sashes that open outward from the centre with no fixed middle post (mullion), providing a completely unobstructed opening and panoramic views. When closed, they offer excellent weather sealing. A beautiful choice for living rooms and feature openings where maximum view and airflow are desired.
Louvre Windows
Louvre windows feature multiple horizontal glass blades that tilt open and closed in unison, allowing precise control over ventilation and airflow direction. When fully open, they provide nearly 100% airflow through the opening — more than any other window type. Ideal for bathrooms, laundries, and tropical-style homes.
Glass Options
All windows come standard with double-glazed insulated glass. Upgrade options available — see our Glass Options page.
Window FAQs
What is the best window type for an Australian home?
Sliding windows are the most popular choice due to their ease of use, good ventilation, and compatibility with fly screens. For maximum airflow, casement windows are ideal. Awning windows are best for wet areas like bathrooms. We recommend a mix of types based on each room's needs.
How much do custom-made aluminium windows cost?
Since every window is custom-manufactured to your exact measurements, costs vary based on size, type, glass selection, and quantity. We provide free on-site measures and detailed quotes across Sydney and Melbourne so you know the exact cost before committing.
Do you supply double-glazed windows?
Yes — in fact, double-glazed insulated glass units (IGU) are our standard specification on all windows. We also offer upgrades including laminated, triple-glazed, low-E coated, and smart tinted privacy glass.
How long from order to installation?
Since every window is custom-manufactured to your exact measurements in our Foshan factory, the lead time from order confirmation to delivery is typically 12–14 weeks. Once delivered, a standard window installation takes 1–2 hours per window, with a full home completed in 1–3 days. All installations come with our 7-year warranty.
