The Trex Decking Installation Guide (2025) provides comprehensive, step-by-step instructions for planning, framing, and installing Trex composite decking across all four major collections—Signature®, Transcend®, Enhance®, and Select®. Updated for 2025, this version reflects Trex’s latest specifications for fasteners, framing spans, gapping, and fascia installation, helping builders deliver safe and lasting outdoor spaces.
Trex decking combines the look of real wood with the low-maintenance performance of composite materials. The guide includes detailed framing and joist-spacing charts, fastening system recommendations, and gapping requirements to accommodate temperature and seasonal movement. It also highlights updates to Trex Hideaway® hidden fasteners, fascia screws, and plug systems for a cleaner, more efficient install.
The 2025 guide expands on best practices for rooftop and sleeper system installations, along with revised drainage and airflow requirements to ensure longevity in a variety of climates. Builders and architects will also find updated warranty coverage summaries, approved span charts for both residential and commercial applications, and product-specific recommendations for Transcend® Lineage, Signature®, and Enhance® decking lines.
In addition to installation steps, the guide includes care and cleaning recommendations for keeping Trex decks looking their best year after year. It outlines safe cleaning agents, surface maintenance techniques, and guidance for addressing snow, ice, and debris without damaging the composite surface. Whether you’re building a large commercial deck or a residential backyard project, this guide provides the latest Trex-approved methods to ensure top-quality results.
