James Hardie supply a combined starter strip with ventilation profile for HardiePlank® cladding. These starter vent strips are manufactured in three thicknesses to suit batten thicknesses of 25mm, 38mm and 50mm.
25mm is the minimum recommended size batten that should be used to allow a free-flow ventilation gap between the cladding layer and the substrate – this is to attain the required gap of 20mm. Additionally it is critical that an air inlet and air outlet gap of at least 10mm is left at the base and at the roofline, also below and above doors/windows. Use a perforated enclosure to prevent pests entering through the ventilation gap.
When installing HardiePlank horizontally it is suggested that the easiest method is to use the HardiePlank combined starter and ventilation profile – this should ensure the first plank is correctly fitted. Alternatively it is feasible to cut a 30mm wide starter strip from a sheet of HardiePlank cladding to kick out the first plank to match the lap of the wall. This should be nailed along the front face of the battens so the lower edge of the starter strip lies along the line made by the bottom of the vertical battens. This provides the lap spacing for the first row of planks. Without this will result in the “kick-out” on the wall appearing inconsistent in the second, third and fourth courses.
When fitting the first layer of HardiePlank cladding a pencil line should be marked 170mm up from the lower edge of the starter strip, make sure that this line is horizontal. This will be the top of the first row of cladding and the spacing gives a 10mm drip edge at the lower edge of the cladding.
