Design Features

1. The Vantage Series 546 is designed to complement the Series 548 Bi-folding door system.

2. The main difference between Series 546 and 548 is the narrow rails.

3. Series 546 uses the same overlight transom as the bifold door plus there is an additional transom for lowlights.

4. Bi-fold windows come in a large variety of combinations (BFW2, BFW4, BFW2+2, BFW6 and BFW4+2 or BFW2+4).

5. Successfully water tested at 300Pa.

6. Mitred perimeter frame for maximum weather performance.

7. Custom injection moulded flush bolt blocks and flush bolt guides remove the need for expensive and unsightly shims and aluminium angles etc.

8. Custom hinges wrap around the window stile and jamb removing the need for notching and shimming. These custom components dramatically improve the appearance.

9. Custom window co-extruded Santoprene seal for maximum weather performance.

10. Bi-fold windows are supported on dual or quad rollers running on heavy duty dual bottom rails.

11. Bi-fold panels can be secured with manual finger operated flush bolts, 'Miro' operated bolt activator or key locking 'Miro' bolt (features illustrated later).

12. Highlights (fixed, awning and/or adjustable glass louvres) can be fitted into tall units.

13. Fixed lowlights can also be fitted under bi-fold panels.

14. Both window panels and fixed sidelights, lowlights or highlights can be double glazed with 19mm insulating glass units.

Safety Note:
On lowlight transom windows in elevated installations treat the lowlight as a balustrade. When the sashes are open there is a large clear opening.
