The uPVC J-Trim is typically used as an edging trim for 9mm soffit and fascia boards to hide exposed edges resulting in a protective and professional finish. Supplied as a 5m length however, can be cut to required size. Also known as a ‘J Trim’, Starter trim is a great way to create a solid, straight base where you can begin installing your cladding. Wall panels slot easily into the purpose made channel, designed to help hide the joins between cladding panels.
