38mm James Hardie Plank Starter Strip and Ventilation Profile, 3m

The 38mm Hardie® Starter Ventilation Profile (Product Code: 5300182) is a vital component for a standard Hardie® Plank horizontal overlap installation. It is fixed at the base of the wall to kick out the first board at the correct angle, ensuring the “overlap” look is consistent all the way up the building. This 38mm profile is used when your project specifications require deeper 38mm battens (often used for extra stability or specific insulation requirements). It provides the necessary kick-out for the first overlap plank while sealing the bottom of the 38mm cavity.

Beyond just setting the angle, this profile is designed to maintain a clear ventilation gap. This allows air to circulate behind the boards, which is essential for keeping the timber battens dry and preventing moisture issues over time.
Made from sturdy aluminium, it provides a much more durable and straighter edge than timber starter strips. It’s a simple addition to your kit list that ensures the job starts level and stays protected from pests getting into the cavity.
