VELUX GGL Centre-Pivot Roof Window – Natural Light & Ventilation for Attics and Lofts

The VELUX GGL is a high-performance, openable centre-pivot roof window designed specifically for in-reach applications such as finished attics, lofts, and upper-storey spaces. Engineered to deliver abundant natural light and reliable passive ventilation, it’s the ideal solution for transforming underutilized spaces into bright, breathable areas.

✅ Key Features & Benefits

  • Top-Control Bar Operation:
    A single short pull activates a built-in ventilation flap, allowing fresh air to enter even when the window remains securely closed—perfect for maintaining indoor air quality during inclement weather.

  • 180º Centre-Pivot Design:
    A second pull on the control bar rotates the window fully up to 180 degrees, allowing for maximum airflow and easy cleaning of the outer pane from the safety of inside the room.

  • Premium Finish:
    Constructed with a white pre-painted pine sash and frame, blending durability with a clean, modern aesthetic that complements any interior.

  • Durable Exterior Protection:
    Comes fully equipped with aluminum cappings and flashing kits, making it compatible with both tile and corrugated metal roofs, ensuring a weathertight installation.

  • Versatile Sizing:
    Available in five standard sizes to suit a variety of room dimensions and roof pitches.

  • Enhanced Glazing:
    Standard laminated double glazing offers superior thermal insulation and added security.

  • Optional Insect Screen:
    Add an insect screen (sold separately) for enhanced comfort and bug-free ventilation during warmer months.


Whether you’re renovating your attic or finishing a new loft conversion, the VELUX GGL Roof Window delivers function, style, and fresh air, all in one innovative unit.
