    Key Features

    • The Vantage Series 546 Bi-fold window is designed to complement the Series 548 Bi-folding door system.
    • The main difference between Series 546 and 548 is the narrow horizontal rails.
    • Series 546 uses the same overlight transom as the bi-fold door plus there is an additional transom for lowlights.
    • Bi-fold windows come in a large variety of combinations (BFW2, BFW4, BFW2+2, BFW6 and BFW4+2 or BFW2+4).
    • Successfully water tested at 300Pa.
