Rubin 9V is the largest ceramic roof in the Braas range. The large format combined with the possibility of sliding up to 30 mm gives the roof a universal sash that can be used not only on large and straight roofs.

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 roof surface, hence the symbolic name "chestnut".
