Trex® Enhance®, Transcend® and Select® Fascia Boards (Figure 2) is for use as nonstructural trim components for exterior balconies, porches and decks of Type V-B (IBC) construction, and in structures constructed in accordance with the IRC. 3.0 DESCRIPTION 3.1 General: Trex® composite decking is a wood thermoplastic composite lumber (WTCL) deck board and fascia, with an integrated shell that covers the boards on the top surface and sides. The underside of the boards and fascia is not covered by the integrated shell. The integrated shell consists of a proprietary surface formulation that produces a natural, wood-like grain pattern finish. The deck board and fascia are made from approximately 50 percent wood fiber and 50 percent polyethylene by weight, and are alternatives to preservative-treated or naturally durable lumber. Trex® composite decking is manufactured by a continuous extrusion process and is available in varies colors, sizes, and textures per each product as described in Sections 3.1.1, 3.1.2, and 3.1.3. The Trex® Hideaway® hidden fastening system (Figure 3) is described in Section 3.1.4. The attributes of the Trex® composite decking have been verified as conforming to the provisions of (i) CALGreen Section A5.406.1.2 for reduced maintenance; (ii) ICC 700-2012 Section 602.1.6 and 11.602.1.6 for termite-resistance materials and Section 601.7, 11.601.7, and 12.1(A).601.7 for site-applied finishing materials; and (iii) ICC 700-2008 Section 6.2.8 for termite-resistant materials and Section 601.7 for site-applied finishing materials. Note that decisions on compliance for those areas rest with the user of this report. The user is advised of the project-specific provisions that may be contingent upon meeting specific conditions, and the verification of those conditions is outside the scope of this report. These codes or standards often provide supplemental information as guidance.

The Select composite decking has square-edge and grooved-edge profiles. The square-edge deck boards are 15/16-inch-thick-by-5½-inch-wide nominal (20 mm by 140 mm) or 13/8-inch-thick-by-5½-inch-wide nominal (33 mm by 140 mm). Grooved-edge deck boards are 15/16-inch-thick-by-5½-inch nominal (25 mm by 140 mm). The Select® composite fascia are ¾-inch-thick-by-7¼-inch wide (17 mm by 184 mm) and ¾-inch-thick-by-11¼-inch- wide (17 mm by 288 mm) profiles. 3.1.4 Trex® Hideaway® Hidden Fastening System: The hidden fastener system is designed specifically for Trex® composite deck boards having grooved-edges and consists of a stainless steel clip or a plastic universal clip and No. 8 by 2-inch-long (51 mm) stainless steel flathead screw. 3.2 Durability: When subjected to weathering, insect attack and other decaying elements, the deck board and fascia material are equivalent in durability to preservative-treated or naturally durable lumber. Accordingly, the material is permitted to be used as an alternative to preservative-treated or naturally durable lumber on exterior decks, porches, balconies and stair treads, as applicable. The deck board and fascia have been evaluated for use in ambient air temperatures between -20°F (-29°C) and 125°F (52°C). 3.3 Surface-burning Characteristics: When tested in accordance with ASTM E84, Trex® composite boards have a flame-spread index no greater than 200. 4.0 DESIGN AND INSTALLATION 4.1 Design: Allowable Stresses: Table 1 lists allowable stress values only for the Trex® Transcend® decking recognized in this report. These values must not be adjusted. 4.2 Installation: 4.2.1 Deck Boards: The deck boards maybe installed perpendicular or at an angle to the supporting construction, Table 2 lists the maximum spacing for deck boards installed perpendicular or at an angle to the supporting construction.. The deck boards must be spaced at edges and ends in accordance with the manufacturer’s published installation instructions. 4.2.2 Deck Boards Used as Stair Treads: The deck boards, when used as stair treads, are sufficient to resist the code-prescribed concentrated load of 300 lbf (1.33 kN) when installed at a maximum center-to-center spacing as indicated in Table 3. 4.2.3 Deck Board Fasteners: Trex® “grooved-edge” boards, when installed perpendicular to the supporting construction with the Trex® Hideaway® Stainless Steel or Universal Hidden Fastener Systems with No. 8 by 2-inch (51 mm) stainless steel flathead screws, have an uplift rating of 100 psf (4788 Pa) up to a maximum span of 16 inches (406 mm) when installed at each support. Trex® “square-edge” solid boards (no edge groove) are installed with two No. 8 or No. 10 by 21/2-inch (63.5 mm) wood screws at ends to each support, at least 1 inch (25.4 mm) from the board end and sides. The allowable fastener head pull-through capacity for the screws is 237 lbf (1054 N) per fastener. Multiple joists or blocking must be used to provide adequate surface for fastener embedment at board ends. 5.0 CONDITIONS OF USE The Trex® composite deck boards described in this report comply with, or are suitable alternatives to what is specified in, those codes listed in Section 1.0 of this report, subject to the following conditions: 5.1 The Trex® composite decking is limited to exterior use as deck boards for balconies, porches, decks and stair treads of Type V-B (IBC) construction and structures constructed in accordance with the IRC. 5.2 The Trex® composite fascia is limited to exterior use as trim for balconies, porches and decks of Type V-B (IBC) construction and structures constructed in accordance with the IRC. 5.3 Installation must comply with this report, the manufacturer’s published instructions and the applicable code. When the manufacturer’s published installation instructions differ from this report, this report governs. 5.4 The use of the Trex® composite decking and fascia as a component of a fire-resistance-rated assembly is outside the scope of this report. 5.5 The compatibility of the fasteners with the supporting construction, including chemically treated wood, is outside the scope of this report. 5.6 The deck boards must be directly fastened to supporting construction. Where required by the code official, engineering calculations and construction documents consistent with this report must be submitted for approval.
