Fixed windows are available in a myriad of configurations, sizes and shapes. You can customize mullions and grids for a heritage feel or go for a huge modern uninterrupted view. Considerations which impact cost are aspect ratio, overall size, sill height (tip: keeping the sill above 500mm will remove the need for safety glass and reduce costs in most cases, other than wet areas and around stairwells). Bush Fire rating has an impact on cost from BAL19 upwards.
Unilux triple glazed windows use low iron super clear glass for excellent light transmission and Solar Heat Gain.
