The eco-friendly alternative to wood

Castlewood Ultraguard 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.
All stocked in our warehouse in Central Scotland.

As well as composite decking we also offer composite decking tiles, Composite cladding, composite fencing and other accessories for delivery across Scotland, England and Wales.
