Millboard Composite Decking

Decking can make your garden fell more like an outdoor living room, helping create an outdoor dining area or a calm place to relax with a book and much more!

Why choose Millboard?

Millboard combines the natural beauty of real wood with the high performance of polyurethane, a material widely recognized for its strength. Polyurethane is used in many industries where durability and strength is required, eliminating the inevitable rotting, warping and deterioration of natural wood. Millboard maintains a functional and highly attractive deck for years to come.


The unique Lastane layer resists scratches and stains and is designed to withstand more demanding outdoor environments than timber can.


The dual-tone Lastane surface is hand tinted using pigments designed to replicate the look of natural timber


Millboard is wood-free and non-porous, which means high resistance to algae growth and excellent anti-slip properties.


Our unique. closed 'cellular' internal structure reduces weight while maintaining strength.


The structural core is a blend of natural minerals bonded in a polymer resin with long fibre reinforcement for added strength.


Millboard decking is solid, not hollow. This makes it strong and means it won't warp, rot or harbour insects and pests like timber would.
