About Coastal Composite Decking
NewTechWood Coastal Decking brings the character of weathered timber to outdoor spaces with the durability and low maintenance of composite decking. Featuring distinctive 210mm wide boards with a deep timber-like texture, Coastal is particularly suited to Coastal and Hamptons-style homes.
The boards are fully capped for 360° protection, helping resist stains, mould, UV and pests while eliminating the need for regular oiling, sanding or painting. The range combines a natural timber look and feel with long-lasting performance for both residential and commercial applications.
Available in Antique, Beech, Teak and Aged Wood, Coastal is made from 95% recycled material and uses a hidden clip system for a clean finish. It is also BAL 29 rated and well suited to outdoor living areas and pool surrounds.
