Topasa's elegance is due to its factual, subtle style. The result: the house gives a homogeneous, balanced impression. Topas 13V is a roof that gives a noble character to both new constructions and older buildings. The color differences of the chestnut roof are the intended effect. To achieve a beautiful, varied roof surface, mix the roof into different pallets during installation. As a result, we obtain a uniform transition of dark color to light across the entire surface of the roof, hence the symbolic name "chestnut".
