Vertical Bi-Lite
Roof Windows
Keylite Vertical Bi-Lite (VBL) Roof Windows are the ideal way to maximise the light and ventilation into any room.
Keylite VBL roof windows are available in a variety of styles and combinations. Arranging your Keylite Roof Windows to incorporate a Keylite VBL creates a larger glazed area, and increases light into your living area.
The roof and vertical windows combine seamlessly at eaves level.
For “tilt and turn” prices and options, contact the Keylite Sales Team.
Standard vertical windows are available as tilt only.
Keylite VBL’s are designed to complement the Keylite Roof Windows overhead, and are suited to any property.
