The eco-friendly alternative to wood

Castlewood polymer capped composite decking is one of the most attractive and durable decking boards on the market. Castlewood combines the proven strength of high density polythene plastic and wood fibres with an outer shell of polymer that completely encapsulates the board in an impermeable layer of protection from scratches, stains and fading.

Castlewood decking boards are manufactured from 95 percent recycled materials including clear plastic bottles and reclaimed wood fibres, which are an excellent eco-friendly alternative to wood.
