Why Composite Deck Boards

AT® composite deck boards made from polymer and high quality beech woood flour.

As a top quality composite decking product, our AT® composite deck boards do not need staining, painting or treating during its long life. The polymer content limits moisture absorption to very small amounts i.e. below 1% compared with over 25% for untreated timber*.

*Water absorption is the cause of warping, swelling and distortion in timber products and is the main reason expensive and time consuming treatments are specified to validate any guarantee offered with timber products.

No need to paint, stain or seal – a chore required each year with traditional timber decking. The nature of composite decking means you will not need to replace rotting, split or uneven boards saving you time and money.

Heat and Fade Resistant

Whichever colour you choose, it will stay naturally beautiful for years to come and with virtually no maintenance.

Your AT® composite deck boards will also stay cool to the touch – even on the hottest of days.


Composite decking has slip-resistant walking surfaces and, unlike traditional wood, is splinter-free, so you can relax and enjoy. Because composite decking surface is slip-resistant it is ideal for pool decks and spa surrounds.


Traditional timber decks start out looking beautiful – but within a short time you will start to notice a difference.  Rainy springs, hot summers and cold winters quickly have a detrimental effect leaving the timber deck splintered, warped and tired looking. Our composite decking is made from a patented process that results in superior, consistent, low-maintenance material. All composite decking products come with a 25 year warranty.
