BOARD TYPES
Explore our range of composite decking boards by clicking on the images below. Once you’ve identified the style and colour that best suits your space, contact us to arrange a visit with samples.
Timbertech/AZEK
TimberTech / AZEK boards feature a recycled PVC core encased in a proprietary polymer blend. This construction offers robust protection against the elements and provides a variety of colour options for customisation.
MILLBOARD
Millboard decking combines recyclable polyurethane with mineral resin to form a durable core. This core is encased in a unique Lastane® layer that not only protects the board but also conceals screw heads by resealing over them, resulting in a seamless finish.
TREX
Trex boards consist of 95% recycled materials, forming a wood-plastic composite (WPC) core. A protective polymer cap wraps around the top and edges, safeguarding against wear while allowing the uncapped bottom to breathe.
EVA-LAST
Eva-Last’s Pioneer boards feature a glass fibre-reinforced foamed PVC core for enhanced strength. The surface showcases a photorealistic print, protected by a clear wear layer that ensures colour longevity and resilience.
