Fixed Window FAQs

Fixed windows are non-operable windows designed solely to admit natural light and provide uninterrupted views. Because they don’t open, fixed windows have a clean, minimalist appearance and are commonly used in living rooms, stairwells, feature walls, and high or hard-to-reach areas. In our range, fixed aluminium windows are often paired with sliding or awning windows to balance light, ventilation, and energy efficiency.

In most cases, yes. Fixed windows are typically more affordable than sliding windows because they have fewer components — no rollers, tracks, locks, or moving sashes. This simpler construction also results in lower long-term maintenance costs.

For a detailed comparison of cost, performance, and use cases, see our guide: Sliding Windows vs. Fixed Windows.

Fixed windows are an excellent choice when ventilation isn’t required but light, views, and thermal performance matter. They’re especially popular in modern homes where large expanses of glass are used to open up interiors. Fixed windows also perform exceptionally well in terms of air tightness and energy efficiency, making them ideal for climate-controlled living spaces.

No. Fixed windows are permanently sealed and cannot be opened. When ventilation is required, they’re commonly paired with operable options from our range, such as sliding windows or awning windows.

Fixed panels are also frequently used as low lites or high lites above or beside opening windows, allowing you to maximise natural light while still maintaining airflow and functionality within the same wall or room layout.

The main limitation is the lack of ventilation. Because fixed windows don’t open, they’re not suitable as the sole window type in rooms that require airflow, such as bedrooms and living areas. However, many homeowners overcome this by pairing fixed windows with operable window styles to achieve both functionality and visual impact.

Fixed windows can be made significantly larger than most operable windows. In our Jason Windows range, sizes go up to 2400mm high x 1210mm wide, and 1200mm high x 2050mm wide, depending on configuration and glazing requirements. Larger openings are ideal for feature glazing, raked ceilings, and architectural designs where maximising light is a priority.

Yes — fixed windows are among the most energy-efficient window types available. Because there are no opening sashes, air leakage is minimised. Our range of fixed aluminium windows feature a dual-seal design and can be upgraded with Low-E or double glazing to improve thermal performance further, helping keep homes cooler in summer and warmer in winter.

Jason Windows’ fixed windows combine a clean design with robust aluminium frames and Australian-tested performance. They’re built for WA conditions, available in a wide range of sizes and frame colours, and backed by a 10-year structural warranty. With concealed fixings, toughened safety glass as standard, and compatibility with other Jason window styles, they’re a reliable choice for modern homes, renovations, and architectural builds.
