Hi Marie, the horizontal siding is HardiePlank smooth lap siding with a 5" exposure and this painted fibercement product comes factory finished with a 30 year warranty. In the multifamily housing project below we used HardiePlank in a vertical "board and batten" application (dark grey color). The siding was installed as a ventilated rainscreen over continuous insulation and exterior strapping. A more traditional use of the fibercement product in a vertical application can be seen in the lighter color of the second image. This is the HardiePanel vertical siding with batten strips spaced at 2'.

Thank you so much for your help ! I'll have to check if they have this product in Canada. This is the facade that I want to re-do... I'm desperate :P
