Casement bay and bow units offer contemporary styling, create a roomy feeling, increase ventilation and can be built in many combinations. Bay units are constructed using three windows or more. Flankers are aligned with a center unit at 45° or 30° angles. Bow windows typically feature a series of 3-6 casements mulled as a radius. Bay/Bow windows may include factory-assembled head and seat boards and a cable kit to compensate for overhanging weight and aid in installation.
