Double-glazed uPVC windows, made in Melbourne
Fixed windows
A fixed window doesn't open, so all of it can be glass and view. Use one on its own, or pair it with any of our opening windows.
Why choose fixed windows
Maximum glass
With no opening sash, more of the window is glass and less is frame.
Lowest heat loss
Fixed windows rate down to U-value 0.96 with Low-E triple glazing, our best figure of any window.
Pairs with anything
Combine fixed panes with awning, tilt and turn, casement, sliding or double hung windows in one frame.
Shapes and highlights
Fixed glass suits raked, curved and arched windows, highlights and glass-to-glass corners.

Energy ratings
Whole-window figures for our fixed window, glass and frame together. Lower U-value means less heat lost. Lower SHGC means less summer sun heat let in.
| Glazing | U-value | SHGC |
|---|---|---|
| Baseline4/12/4 clear, manufacturer estimate | 2.35 | 0.63 |
| ToplineLow-E triple glazed, WERS ALU-019-315 | 0.96 | 0.34 |
Figures from the Window Energy Rating Scheme (WERS) unless marked as a manufacturer estimate. U-value in W/m²K. Other glass options sit between these two points. How to read window ratings

Common questions
Are fixed windows more energy efficient than opening windows?
Generally, yes. With no opening sash there are fewer seals and less frame. Our fixed windows rate down to U-value 0.96 with Low-E triple glazing (WERS ALU-019-315).
Can fixed windows be made in custom shapes?
Yes. We make raked, curved, arched and joined-glass windows to your measurements. Send us your plans or measurements and we'll quote them.
How long does it take to get my fixed windows?
Most jobs take 8 to 12 weeks from approved quote to installation. Timing depends on our production schedule, and on lamination if you choose a colour we don't keep in stock.
Do you install, or supply only?
Both. For new homes, builders typically order supply-only and install using our drawings and installation details. For replacements in existing homes, our certified installers can complete the job for you.
