Double-glazed uPVC windows, made in Melbourne
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.
With no opening sash, more of the window is glass and less is frame.
Fixed windows rate down to U-value 0.96 with Low-E triple glazing, our best figure of any window.
Combine fixed panes with awning, tilt and turn, casement, sliding or double hung windows in one frame.
Fixed glass suits raked, curved and arched windows, highlights and glass-to-glass corners.
Every window is made to measure. These are the layouts in our quote builder. For anything else, send us your plans.
