It is not recommended to use Grey Wooden Ceramic for exterior applications in very windy climates. Ceramic tiles are not very flexible and can crack or break if they are subjected to too much stress. Furthermore, high winds can also cause debris and other objects to damage the surface of the tiles. If you do decide to use Grey Wooden Ceramic for exterior applications in a very windy climate, make sure to consult with a professional to ensure that the installation is done correctly and that the tiles are properly reinforced to withstand the additional stress.
