Energy efficient performance from VELFAC

VELFAC glazing is designed to deliver comfortable spaces in which to live or work, and our expert team can optimise window performance for every room by tailoring specification to reflect window position, room orientation and containment. Selecting from over 10,000 glass types, we determine the ideal balance of window and glass to achieve the desired result, providing the holistic consultancy required to deliver an energy efficient and comfortable build.
