They are a functional block and are manufactured in two finishes, standard and paint grade. The standard finish offers an excellent plastering key for rendering or can dry lined with plasterboards. Our paint grade finish is ideal for walls to receive a range of proprietary paints, the appearance is then of an aesthetic one.
