Building Codes: 2006 International Building Code (IBC) 2006 International Residential Code (IRC) 2009 International Building Code (IBC) 2009 International Residential Code (IRC) 2.2. Properties: Structural Performance Durability Surface Burning Decay Resistance Termite Resistance 3.0 Description 3.1. General DecKorators CXT railing systems are offered in two styles, Contemporary and Colonial, and are guardrails (guards) under the definitions of the referenced codes. Guards are intended for exterior use at or near the open sides of elevated walking areas in buildings and walkways, including stairs and ramps, as required by the referenced codes Guard Assemblies Guards are provided as level guards for level walking areas such as decks, balconies, and porches, and as sloped guards for open sides of stairways Level guards are provided in rail lengths up to 96 inches between supports and an installed height of up to 42 inches. See Table 1 for qualified lengths and configurations Stair guards are provided in rail lengths up to 72 inches measured along the sloping length between supports and an installed height of up to 42 inches at the leading edge of the stair tread or landing. See Table 1 for qualified lengths and configurations Materials and Processes DecKorators CXT railing systems are an assemblage of an extruded wood-plastic composite (WPC) material along with other metal, glass, and plastic parts. The WPC components are produced in two colors: White and Black The guard system includes a top rail, a bottom rail, vertical balusters, non-structural 4 inch square post sleeves, rail-to-post brackets, support blocks, decorative moldings, and post caps. See Figure The top rail is comprised of two parts: a co-extruded WPC inner rail with overall dimensions of inches wide by inches tall (see Figure 2) combined with one of two contoured co-extruded WPC profiles: The Contemporary top rail has overall dimensions of 3.40 inches wide by 2.18 inches tall with a 0.25 inch wall thickness. See Figure The Colonial top rail has overall dimensions of 3.40 inches wide by inches tall with a 0.28 inch wall thickness. See Figure The bottom rail is a U-shaped co-extruded WPC rail with dimensions of 2.86 inches wide by 1.85 inches tall with a 0.25 inch wall thickness. See Figure Top and bottom rails are attached directly to structural supports with 304 stainless steel mounting brackets. See Figure 8 and Figure Structural supports may be conventional wood framing. A co-extruded WPC post sleeve is utilized to sleeve a conventional 4x4 wood post. See Figure The infill area may be configured in multiple ways using WPC, glass, or aluminum balusters attached to a WPC rail.

2 Page 2 of Balusters are provided in several styles, including glass, aluminum, and WPC: - Square, Solid WPC (Figure 7) - Square, Co-Extruded, Hollow WPC (Figure 19) - Frontier Glass (Rectangular) (Figure 10) - Contoured Glass (Figure 12) - Square (Estate) 6063-T6 Aluminum (Figure 17) - Round (Classic) 6063-T6 Aluminum (Figure 18) See Table 2 for fastening schedule Support blocks are installed between the lower rail and the deck surface. Two supports are used for rail lengths up to 6 ft, and three supports are used for rail lengths up to 8 ft (24-inch maximum spacing between supports). 4.0 Performance Characteristics 4.1. The guardrail system described in this report has demonstrated the capacity to resist the design loadings specified in Chapter 16 of the IBC and Section R301 of the IRC when tested in accordance with ICC-ES AC174 and ASTM D Structural performance has been demonstrated for a temperature range from -20 F to 125 F Materials used are deemed equivalent to preservative treated or naturally durable wood for resistance to weathering effects, decay, and attack from termites The WPC material used in the guardrail system has a flame spread index of 35 when tested according to ASTM E 84. The referenced criteria, AC174, requires the material to have a flame spread index not greater than 200 when tested according to ASTM E Installation 5.1. The guardrail system shall be installed in accordance with the manufacturer's installation instructions and this report. Where differences occur between this report and the manufacturer's installation instructions, this report shall govern The top and bottom rails are attached directly to structural supports utilizing 304 stainless steel mounting brackets. See Figure 8 and Figure The top and bottom rails may be attached to conventional wood supports. Conventional wood supports including wood posts are outside the scope of this report Guards may be assembled in various configurations. Refer to Table 2 for the fastening schedule x4 conventional wood posts may be covered by a non-structural WPC post sleeve with decorative caps and moldings Round balusters are secured to the top and bottom rail via various connectors. See Table 2, Figure 20, Figure 23, Figure 24, Figure 25, and Figure Square aluminum balusters are secured to the top and bottom rail via plastic connectors. See Table 2, Figure 21, and Figure Glass balusters are secured to the top and bottom rail via plastic connectors. See Table 2, Figure 11, and Figure Glass, aluminum, and WPC baluster connectors are attached to the rails using stainless steel screws. See Table The wood in the supporting structure including support posts shall have a specific gravity of 0.50 or greater (Southern Yellow Pine or better) and a minimum thickness to allow full penetration of the bracket mounting screws. 6.0 Supporting Evidence 6.1.
