Composite Decking Installation Guide

---

This installation guide outlines best practices for installing composite decking, including framing layout, board spacing, and fastening methods.

We are currently updating this guide to reflect the Dual 360 composite decking system. In the meantime, the process remains largely the same, and this guide can still serve as a reliable reference for installation.

For the most accurate guidance, we recommend following the Advanced decking installation method, as it closely aligns with the Dual 360 system. The Prestige decking method can also serve as a general reference, though there are some differences in the installation approach.

The main difference with Dual 360 decking is the updated hidden fastener system, which includes a locking clip designed to help control board movement while allowing for natural expansion and contraction.

For the best results, follow recommended joist spacing, fastening guidelines, and use compatible Dual 360 system components throughout your build.
