37" x 100" BA-FGH-V-P2 Deck Mounted Balcony Window

The 37" x 100" BA-FGH-V-P2 Deck Mounted Balcony Window transforms an attic or loft roof opening into a functional balcony in seconds. The upper sash opens steplessly upward to 45 degrees while the lower sash tilts forward to a vertical position with integrated side railings that extend automatically, creating an open-air balcony recess with sky views and fresh air.

When closed, the balcony railings retract and hide beneath the window flashing, keeping the roofline clean. P2 laminated safety glazing, a vacuum-impregnated pine frame, and the TopSafe reinforced structure combine daylight, ventilation, and increased burglary resistance in one striking roof window.

Why Choose 37" x 100" BA-FGH-V-P2 Deck Mounted Balcony Window?

  • Balcony in Seconds: The upper sash raises to 45 degrees and the lower sash tilts forward to form a functional balcony with integrated rails that extend during opening.
  • Concealed Retractable Railings: When the lower sash closes, the balcony railings hide inside the window beneath the flashing, so they do not collect dirt or spoil the roofline.
  • P2 Laminated Safety Glazing: Both sashes use P2 laminated glazing with a toughened outer pane and easy-maintenance coating for safety and durability.
  • Built-In Ventilation: An automatic V40P air inlet provides fresh airflow even when the window is closed.
  • Easy-Clean Design: The upper sash rotates inward so the external glass can be cleaned safely from inside.
