Product Details

James Hardie supply a combined starter strip with ventilation profile for HardiePlank® cladding. The JamesHardie Starter Strip is manufactured in three thicknesses to suit 25mm, 38mm and 50mm battens.  These Starter strips are 3.0 metres long

Battens and ventilation

The minimum recommended size batten that should be used to allow a free-flow ventilation gap between the cladding layer and the substrate is 25mm.  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, above doors and windows. Using  a perforated enclosure helps to prevent pests entering through the ventilation gap.

Combined JamesHardie starter and ventilation strip

When installing HardiePlank horizontally the easiest method is to use the HardiePlank combined starter and ventilation profile. This should ensure the first plank is correctly fitted.  Alternatively you can 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. Then this strip should be nailed along the front face of the battens so the lower edge of the starter strip lines up with the bottom of the vertical battens. Consequently this provides the lap spacing for the first row of planks. Without this starter strip means the “kick-out” on the wall appears inconsistent in the second, third and fourth courses.

We stock the JamesHardie Starter Strip in three thicknesses to suit batten thicknesses of  25mm, 38mm and 50mm.

Fitting the first HardiePlank cladding layer

When fitting the first layer of HardiePlank cladding a pencil line should be marked 170mm up from the lower edge of the starter strip.  Because this will be the top of the first row of cladding it is important that the line is horizontal. Also this spacing gives a 10mm drip edge at the lower edge of the cladding.  Finally Gecko Gauges are ideal for speeding up HardiePlank installations if there is no second pair of hands.
