Discover our aluminium perforated closure trim
The Cladco 3m aluminium perforated closure trim is a key component when installing Cladco fibre cement wall cladding boards, as well as our Signature and ProClad composite wall cladding ranges. Designed with evenly spaced perforations, it promotes airflow and ventilation while preventing insects, small animals, and debris from getting behind the boards.
The ventilation gaps in the closure trims, combined with the recommended 50mm spacing between battens and boards, help ensure consistent airflow behind the cladding, reducing the risk of moisture build-up and improving long-term performance.
Each trim is made from corrosion-resistant, durable aluminium, offering superior strength and long-lasting protection. The trims are supplied in 3m lengths and measure 40mm in width.

To install the trim, fix it to the base of your structure before fitting the first cladding board. For proper ventilation and protection, trims should also be installed above any windows and doors where fibre cement boards will be applied. Please read our fibre cement lap wall cladding installation guide for further information.

Please note: It’s recommended to leave a 10mm gap between the closure and the base of your installation to allow for adequate airflow. Ensure the closure is level before fixing it to the wall, as the 3m fibre cement wall cladding start profile trim will be attached directly to it. An uneven closure may result in misaligned cladding.
