Sometimes a mixture between Formboard top pine and CELLON is the right solution, and a number of school buildings in Winterthur designed by the same company exemplify this very well. While the planners used CELLON in areas subject to more weathering, they chose to use Formboard in the other areas. The fact that they used the same surface materials means that you can hardly tell the difference where Formboard top pine and CELLON have been used. This well-thought out combination of our materials – that took into consideration the applications to which they are best suited – resulted in real cost savings.
