Holonite supplies stronger window sills such as type W, X, Y and Z for traditionally designed buildings. These window sills hollowed out on the underside are intended as a means of cutting down on materials. These window sills are also available without a hollowed-out section for a surcharge. Window sill type Z is perfect for combining with a type Z bracket to create a continuous band along the façade.
