VFA & VFB are tilt and turn elements that can be installed vertically in the facade as an addition below a centre-pivot or top-hung roof window on roof pitches between 15-55°. 

The sash opens inwards from a handle positioned on the side of the sash. The VFA is hinged on the left (when viewed from inside) and the VFB is hinged on the right (when viewed from inside) meaning they are suitable for escape/rescue opening purposes.

The VFA & VFB windows allow even more daylight and offer great views when standing or when seated.

The frame and sash are made of high-quality laminated pinewood coated with impregnation and layers of water-based acrylic clear lacquer or white paint.

Externally the windows has maintenance-free cover parts.
