The Science Behind Millboard Decking: Crafting the Ultimate Outdoor Flooring Solution

how millboard decking is made

In the world of outdoor decking, innovation is key. Enter Millboard, a revolutionary wood-free decking material that combines cutting-edge technology and craftsmanship to deliver unmatched performance and aesthetic appeal. In this blog, we’ll take you behind the scenes and explore the intricate process of how Millboard decking is made, highlighting its distinctive features and applications that make it the go-to choice for architects, builders and homeowners alike.

Non-Porous and Algae-Resistant Composition

Millboard’s unique composition sets it apart from traditional decking materials. Being wood-free and non-porous, it boasts remarkable resistance to algae growth. This attribute makes it ideal for applications in areas prone to moisture, such as around pools, coastal or areas that see a lot of rainfall. The anti-slip properties further enhance safety in these spaces, making Millboard composite decking a perfect blend of beauty and functionality.

Dual-Tone Lastane Surface

The exquisite appearance of Millboard decking begins with its dual-tone Lastane® surface. This layer is meticulously hand-tinted using specially formulated pigments designed to resist fading and damage from prolonged sun exposure. This means your Millboard decking boards will retain its vibrant hues and sophisticated aesthetic for years to come, making it a perfect choice for spaces where visual appeal is paramount.

Innovative Structural Core

At the heart of Millboard composite decking lies its structural core – a blend of natural minerals bound in a polymer resin. This core is fortified with long fibre reinforcement, adding an extra layer of strength and durability. This unique composition not only ensures Millboard’s longevity but also contributes to its exceptional resistance against warping, rot, and insect infestations, making it a reliable choice for outdoor decks, patios, and outdoor entertainment areas.

Solid Design for Uncompromising Strength

Unlike some hollow alternatives, Millboard decking is solid through and through. This design choice is a testament to its commitment to strength and longevity. The solid composition guarantees that your Millboard deck can withstand the test of time, even in the harshest of weather conditions. Say goodbye to concerns about warping, and hello to a deck that stands strong for years.

Lightweight ‘Cellular’ Internal Structure

Despite its solid build, Millboard surprises with its lightweight nature. Thanks to its unique ‘cellular’ internal structure, the decking boards are able to maintain their strength while shedding unnecessary weight. This innovation not only aids in easy installation but also offers flexibility in design applications, making it an excellent choice for elevated decks or projects where weight considerations come into play.

Lastane® Layer: The Ultimate Shield

The Lastane® layer of Millboard composite decking boards is a game-changer when it comes to resilience. This top surface not only resists scratches and stains but is also engineered to endure the rigours of demanding outdoor environments. From the scorching sun to heavy foot traffic, Millboard’s Lastane® layer remains steadfast, maintaining its beauty and functionality without compromise.


Millboard composite decking is not just an outdoor flooring solution; it’s a testament to innovation, quality, and design excellence. From its non-porous and algae-resistant composition to the meticulously hand-tinted dual-tone Lastane® surface, each element of Millboard is crafted with precision and care. The result is a decking material that combines the allure of natural wood with the resilience of advanced technology. Whether you’re envisioning a poolside paradise or a charming outdoor retreat, Millboard decking is the embodiment of form and function, elevating your outdoor spaces to new heights.
