Natura Wood Effect Cladding Two-Part Aluminium Corner Trim for Barnwood Oak (RAL 1019M) is designed to create a neat and tidy finish on external corners when you’re cladding the sides of buildings or window returns. This trim consists of two components: the base trim and the front cover trim. Start by fitting the base trim seamlessly into it, and then add the front cover trim for a polished look. Available in a range of colours, our aluminium corner trim coordinates seamlessly with your chosen wood-effect cladding. Each trim comes in a convenient 5-metre length.
