The TimberTech Advanced PVC Decking Installation Guide (PDF) provides complete, step-by-step instructions for installing TimberTech’s high-performance Advanced PVC decking (formerly AZEK Deck). This guide covers installation preparation, framing requirements, top-down fasteners, grooved-board hidden fasteners, rooftop deck considerations, and best practices for minimizing movement in extreme temperatures.
The guide starts with essential preparation steps including proper joist spacing—16″ on center maximum for standard installation, 12″ on center for diagonal or commercial applications, and up to 24″ on center for MAX boards. Instructions emphasize checking joists for plane, using solid blocking every 4’–6′, and avoiding floating substructures in all installations, especially rooftop applications. TimberTech stresses that Advanced PVC decking must be installed embossed-side up and should not be used as beams, posts, or load-bearing elements.
Comprehensive fastener sections cover Cortex® plugs, CONCEALoc® clips, FUSIONLoc® pneumatic fasteners, and SIDELoc® side-fastening systems, with detailed diagrams for screw placement, joist doubling at butt joints, and best practices for preventing movement, squeaking, or surface damage. Installers working with grooved boards will find full routing instructions for creating start/stop board grooves, while square-edge boards include guidance for top-down fastening or use of SIDELoc.
Special sections address rooftop decks, where secure structural attachment, airflow, and drainage are critical. Warnings include avoiding metal shavings, rubber-backed mats, and high heat from Low-E glass reflection. The guide also covers diagonal installation, stair stringer spacing, picture-frame framing, and replacing damaged boards.
Advanced PVC fascia installation instructions outline fastening patterns, construction adhesive usage, required backing, and spacing recommendations to minimize expansion and contraction. The guide concludes with care and maintenance guidance, including approved cleaners, snow removal recommendations, storage notes, and cautions against masonry dust and chemical spills.
