Millboard Enhanced Grain Composite Decking Boards

Experience the authentic beauty of real timber with Millboard® Enhanced Grain Composite Decking, a premium decking range that combines exceptional realism with advanced material performance. Designed and manufactured in the UK by Millboard, Enhanced Grain boards are hand moulded from genuine oak boards, capturing the depth, texture, and natural imperfections of real timber.

Unlike traditional composite decking, Millboard contains no wood fibres. Instead, each board is constructed using a polyurethane resin core reinforced with mineral fibres, making it highly resistant to moisture, rot, mould, and insect attack. The surface is finished with Millboard’s proprietary Lastane® layer, a flexible yet durable coating that delivers excellent slip resistance, colour stability, and long-term durability. With concealed fixings and no need for sanding, staining, or oiling, Enhanced Grain decking offers refined aesthetics with minimal maintenance.
