Anthracite Composite Cladding Internal Corner 3.6m — Series 1

Finish the internal corners of your anthracite composite cladding installation with our Anthracite Internal Corner profile. Part of the Series 1 accessories range, this 3.6m trim sits neatly inside the corners of garden buildings, recessed wall sections, and any internal angle where two cladding surfaces meet — delivering a clean, professional result that conceals raw board ends and prevents moisture ingress at the join.

Matching the cool, contemporary tones of Anthracite composite cladding, this internal corner profile ensures a fully coordinated, seamless look throughout your cladding project. Anthracite is one of the most popular modern cladding colours, and finishing internal corners correctly is what separates a truly professional installation from an amateur one. This trim makes it straightforward, providing a precise, consistent angle every time.

Manufactured from the same durable composite material as the cladding boards, this corner trim is UV stable, frost resistant, and completely maintenance-free once installed — no painting, sealing, or annual treatment required.
