The Natura Wood Effect Cladding Two-Part Aluminium H Trim for Barnwood Oak (RAL 1019M) effectively conceals the joint between the boards, creating a neat and weatherproof finish, quicker than using the butt joints. The two-part design allows for a straightforward installation. Simply fit the base section first, install your cladding boards, and then snap the top cap into place for a finished look. Available in a range of colours to perfectly complement your chosen Natura Cladding wood finish.
