20mm Hardie Plank Cobble Stone Internal Corner, 3m

The Hardie™ 20mm Internal Corner Trim in Cobble Stone is an essential aluminium profile used to create a neat, professional finish where two cladded walls meet at an inside corner. Designed to work with both Hardie® Plank and Hardie™ VL Plank, this trim ensures your corners stay weather-tight while neatly concealing the cut ends of your boards.

Applications & Usage: This profile is used specifically for internal corners. It provides a clean, recessed look that allows your cladding to “tuck” into the corner, protecting the fibre cement core from moisture and debris. The Cobble Stone finish is an exact match for your James Hardie planks, ensuring the corner blends in perfectly for a warm, neutral appearance.
Using these colour-matched aluminium trims is a far superior alternative to using timber or plastic, as they won’t rot, warp, or require repainting. They are a vital part of a warranty-approved installation, maintaining the necessary gaps for airflow and board movement.

Key Features

Seamless Colour Match: Finished in Cobble Stone to match your cladding for a consistent, warm, neutral colour.

Weather Protection: Shields the cut edges of the planks in internal corners from wind and rain.
