Exterior application is possible. There are however a few considerations. In areas subject to freeze conditions the tiles may experience some micro-cracking if moisture enters the tile and expands. This can be overcome with the correct installation of a moisture barrier between substrate and tile and correct sealing of the tile. Further information should be sought from your experienced installer. Exposure to sun is a further consideration. Under UV conditions the tile colour may fade slightly over time, correct sealant selection and the application of will prevent any significant fading. Verandah and porches are well suited to these tiles as they are not exposed to the above mentioned.
