Cladding Corners, Trims & Fascia

Add a finishing touch to your Millboard Cladding project. With our specially designed Corner Profiles, details around edges are dressed to make the whole project come together.

Our Corner Profiles and Reveal Boards add distinction to corners of buildings, window reveals, door reveals, soffits and much more. Our trims are specially selected to fit our cladding, for a faster and easier install. Also includes the Perforated Closure to aide ventilation and prevent insect infestation.

The Shadow Line⁺ cladding boards have a classification of D-s3, d0, however the Board & Batten range is NOT fire rated and does not carry a 'reaction to fire' certificate. For more information on fire safety please visit millboard.co.uk/help-advice
