About Us
Millboard Composite Decking

Outperform & outlast.

Millboard composite decking combines the natural beauty of real timber with the high-performance benefits of modern materials. Designed and made in the UK, our boards are molded from selected oak samples, creating a unique, authentic wood grain finish. Unlike timber, Millboard won’t rot, warp, or splinter, making it the ideal low-maintenance solution for your clients’ outdoor spaces that demand both style and durability.

Millboard Composite Siding

Elevate Every Exterior.

Millboard’s Envello siding range combines the timeless look of painted timber with the durability of advanced composite materials. Molded from real oak and engineered for long-lasting performance, Envello offers a low-maintenance, weather-resistant solution that enhances the character and protection of any property without the need for regular upkeep.
