Millboard® Cladding

Millboard® Cladding: A Premium Alternative to Timber

Millboard® cladding is unrivalled in quality, aesthetics, and design. With an incredibly realistic and luxurious woodgrain finish moulded from real oak, it offers a premium alternative to traditional timber cladding.

Crafted with a tough surface and a solid core, Millboard® cladding boards deliver exceptional resistance to rotting, warping, UV damage, and scratching. Their advanced composition also enhances the thermal performance of buildings once installed.

Cladding is suitable for both commercial and residential applications and Millboard® cladding can achieve a contemporary, creative finish or a more traditional look—depending on your project.

The colour range offers extensive design flexibility, with options including Limed Oak, Burnt Cedar, Antique Oak, Golden Oak, Smoked Oak, Salt Blue, and Sage Green.

Millboard® Envello Shadow Line+ cladding is ideal for replicating a classic timber exterior, thanks to its smooth, woodgrain finish. Envello Board & Batten+ cladding offers a unique appearance, with four deep grooves that add texture and depth to your walls. You can enhance your Envello Shadow Line+ project with the addition of Envello Décor trims for a touch of sophistication and charm. These luxurious trims are available in ‘Curve’ and ‘Shutter’ profiles, with finish options in Metallic Carbon, Bronze, and Gold.

What is Millboard made of?

Millboard® cladding boards are made from a completely wood-free composition. This consists of a solid core made up of natural minerals that are bonded in a polymer resin, with long fibre reinforcement.


The surface of Millboard® cladding boards is composed of fire-rated elastomer that is chemically melded to the core of the board; this features a UV-stable 2k coating.
