I.Dekk® HD Composite Decking

I.Dekk® HD is the beefier, heavy-duty version of I.Dekk, built for marine and commercial environments with exceptional strength, stiffness, and moisture resistance.

Product Overview

I.Dekk® HD is the heavy-duty version of our original I.Dekk decking, designed specifically for the demands of marine and commercial environments. It is visually identical to I.Dekk, but this sturdier profile features increased stiffness, longer joist spans (up to 24” OC), and a hollow construction for reduced weight. Made from our patented wood-free, PVC-free DuxxBak® mix, I.Dekk HD offers the industry’s lowest moisture absorption, making it ideal for docks, marinas, and waterfront properties.

How is I.Dekk HD different from standard I.Dekk decking?
