Moisture absorption can lead to rot in both wood and composite decking, along with mechanical damage from shrinking and swelling. Class-action lawsuits involving composite decking failures have addressed rot, mold and mildew growth, surface flaking, and cracking. Composites with any exposed wood fiber are susceptible to moisture absorption.<a href=\"#note1\"><sup class=\" wp-image-3992\">1<\/sup><\/a><\/p>\n<p>Manufacturers have developed two methods to protect composite decking from water. The first, and most effective, way is to fully encapsulate the wood fibers in water-resistant plastic, such as polyethylene. Full encapsulation defends against moisture to the board\u2019s core, and allows installers to cut, drill, screw, and nail the boards without creating a pathway for water intrusion. As it is difficult to achieve full encapsulation, many manufacturers have moved from composite-only boards to making decking with a composite core and a protective cap (<em>i.e. <\/em>\u2018capped composites\u2019 or \u2018cap stock\u2019).<\/p>\n<p>Capped composites rely on a thin outer layer of polymer plastic to keep moisture away from the composite core. Caps can be an effective enhancement for deck boards, but are not sufficient on their own to prevent moisture damage when the core is made of a composite that has exposed wood fibers. There are three reasons for this:<\/p>\n<ul>\n<li>some capped composites only have a cap on three sides, leaving the bottom of the board vulnerable to moisture;<\/li>\n<li>even if the cap is on all four sides, both board ends remain unprotected; and<\/li>\n<li>most importantly, jobsite crews breach the cap in many spots when using screws or nails to attach the decking.<\/li>\n<\/ul>\n<p>Newly developed boards combine the added durability of a cap with the moisture defense of composite cores that have fully encapsulated wood fibers. In this case, the cap is used for enhanced resistance to staining, fading, and scratching; it is not primarily for water protection since the composite core is already moisture-resistant.<\/p>\n<p>When choosing any capped decking, it is important to evaluate how well the cap is attached to the composite core. Some manufacturers use proprietary techniques that integrate the cap more completely with the core, which helps prevent delamination.<\/p>\n<figure id=\"attachment_3975\" aria-describedby=\"caption-attachment-3975\" style=\"width: 604px\" class=\"wp-caption alignleft\"><a href=\"http:\/\/www.constructionspecifier.com\/wp-content\/uploads\/2014\/05\/CS_June_2014_HR-86.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\" wp-image-3975\" src=\"http:\/\/www.constructionspecifier.com\/wp-content\/uploads\/2014\/05\/CS_June_2014_HR-86.jpg\" alt=\"The data in the table above was calculated from weights presented in the Wood Database at www.wood-database.com.

Composites, which are made of substantial amounts of inedible plastics, are impervious to insect attack and therefore do not require treatment. Additionally, composite decking with fully encapsulated wood fibers can have direct ground contact and still withstand moisture and insects. This is an important specification criteria, as untreated wood in contact with the ground is a primary pathway for insects to bore into other parts of a deck or structure.<\/p>\n<p><em>Weight<\/em><br \/>\nDepending on the product, composite decking weighs about 45 percent more per unit than the redwood boards used on many home decks, yet is about 45 percent lighter than the ipe hardwood often installed on commercial decked surfaces (Figure 1). In commercial projects, designers therefore typically do not need to make substantial structural modifications to carry the dead loads of composite decking compared to those of ipe and similar hardwoods.<\/p>\n<p><em>Flammability<\/em><br \/>\n<a name=\"note5\"><\/a>WPCs have a fire behavior very similar to, or better than, comparable timber products, according to Tangram Technology, a UK-based consulting engineer firm.<a href=\"#note2\"><sup>2<\/sup><\/a><a name=\"note5\"><\/a> There are some manufacturers introducing capped boards with a Class B fire rating, but, composite decking commonly carries a Class C fire rating, which is similar to the wood structural members commonly used for decks.<\/p>\n<p><em>Surface temperature<\/em><br \/>\nAnecdotal reports indicate dark-colored composite decking, especially more dense products, can become uncomfortably hot for bare feet in direct sunlight. A similar effect happens with dark wood decking. To mitigate this in sunny climates, building professionals can specify lighter color decking.

However, a typical allowed joist spacing for composites\u2014406 mm (16 in.) on center (oc)\u2014is comparable to wood decking. To prevent sagging, it is important to confirm the allowed joist spacing, and allowed cantilever distance, for a given composite deck product and board profile dimensions.<\/p>\n<p><strong>Installation in demanding exposures<\/strong><br \/>\nDue to the superior moisture resistance of high-performance composite decking, the product is being specified for lasting durability in demanding exposures. Examples include marinas, fully submerged access ramps, waterpark decking, and beachfront hotels.<\/p>\n<p><em>Port Royale Marina<\/em><br \/>\nThe owners of the 500-slip Port Royale Marina, on Georgia\u2019s Lake Lanier, are installing moisture-resistant composite decking as part of a multi-million dollar facilities upgrade.

Previously, 2&#215;8 pressure-treated lumber was used. The moisture resistance of high-performance composite decking made it an ideal choice for Port Royale Marina\u2019s decking, which is subject to high-moisture exposure from Georgia\u2019s humid climate and frequent contact with the lake water.<\/p>\n<p>One of the marina\u2019s amenities receiving especially intense water exposure is the children\u2019s spray park. As it includes several water fountains that spray up from the surface, the space required decking that would withstand continual soaking.<\/p>\n<p>In addition to moisture resistance, Brent Pearson, operations manager at TEI Industries, the marina\u2019s owner, noted the high-performance composite decking is a cost-effective choice. Alternatives such as fiberglass are more costly; ironwood or ipe have incredible strength, but can be twice the price of composites.<\/p>\n<p>\u201cIt\u2019s easy to work with, and obviously easier to fasten in place than ipe or concrete\u2014its workability is similar to wood,\u201d Pearson said.<\/p>\n<p><em>Blue Run of Dunnellon Park<\/em><br \/>\nDefending decks, docks, and boardwalks from rot and damaging insects often means keeping boards high and dry.

However, appropriately manufactured composite decking and railing can withstand the most demanding requirements. As a result, it is important to check the manufacturer\u2019s track record to ensure specification of a high-performance product.<\/p>\n<p>In addition to performance, the decking\u2019s appearance is another important factor for many design professionals and project owners. Composite decking manufacturers have become sophisticated at producing attractive materials. For example, composites are available in a multitude of color options, including variegated hues with the look of exotic hardwoods. Many boards also have realistic-looking embossed wood grain patterns.<\/p>\n<p>For building teams seeking a green project rating, composites can contain up to 95 percent recycled content, which can help earn rating points in Leadership in Energy and Environmental Design (LEED) and other green building programs.<\/p>\n<p><a name=\"note6\"><\/a>Due to composite decking\u2019s performance, aesthetics, and use of recycled content, market researchers predict strong growth for the product segment.
