For Trex 5/4x6 deck boards, the joist spacing should be no more than 16" on center for residential applications, which is the same span generally recommended for wood. Trex 2x material should be installed at no more than 20" on center for residential applications and no more than 16" on center for commercial projects. A high strength 2x6 product is available for 24" spans. When installing Trex deck boards on a 45 degree diagonal to the joists, reduce spans by a minimum of 4 inches. See similar questions...

Our Decking's maximum span is 24 inches (however 16" is recommended). Joist spans should be 16 inches on center for residential applications. On long deck surfaces where plank ends are butted, double joists with 3-inch wide Snap Locks are used. Complete engineering specifications are available. See similar questions...

Until a determination has been made through an historical evaluation that your cabin is not historically significant, you will be required to use materials that are similar in design and type as the existing materials. Consideration is given to health, safety and Shasta County building code compliance. If it has been determined that your cabin is not historical, you may use Trex or some other composite decking after approval by the Forest Service. See similar questions...

Trex Wood-Polymer® lumber is made from reclaimed plastic and wood waste in approximately equal proportions. Its durability makes it an ideal choice for decking and landscaping. See similar questions...

Trex decking is made from post-consumer and/or post-industrial reclaimed plastic and waste wood. The reclaimed plastic comes primarily from grocery sacks and stretch film, and the waste wood is from woodworking manufacturers. Unlike plastic lumber, which is typically 100% plastic, Trex decking is approximately 50% wood fiber and 50% plastic. See similar questions...

Trex decking will change color slightly after 10-12 weeks exposure to the sunlight and water. Please see our Weathering page for more information. Yes, Trex decking has a fully-transferable limited warranty unmatched by competitive materials. The Trex decking limited warranty offers coverage against material defects in workmanship and materials, and against splintering, splitting, checking, rot, decay and termite damage, for a full 25 years.

Trex decking readily accepts paint or stain though neither is required for protection. In general, paints or stains which adhere well to wood will adhere as well or better to Trex decking. Quality latex paints (water based) or solid color stains are recommended. Stain and paint applications should be applied according to the manufacturers instructions after the Trex decking fading process is complete. See the Painting Technical Bulletin.

For stains caused by mold, mildew, berries and leaves, conventional deck washes containing sodium hypochlorite work well. For rust stains, ground-in dirt and grime, use cleaners containing phosphoric acid. For grease and oil stains, we recommend that you scrub with a detergent containing a degreasing agent as soon as the stain occurs. Cleaning out your expansion gaps with a flat tool should be done along with any periodic cleaning. For more information see our Care & Cleaning page. See similar questions...

Because of the plastic in Trex decking that surrounds the wood fiber, moisture absorption is extremely low. Trex decking provides a stable, firm, slip-resistant surface - wet or dry. Slip resistance or traction is measured in terms of the coefficient of friction. Trex scores high enough on these types of tests to be considered compliant with the American's with Disabilities Act. See similar questions...

Trex decking has been tested and found to be highly resistant to damage from termites, carpenter ants and marine borers. See similar questions...

Trex decking does not require stains or sealants for protection. All you need to do to your Trex deck is to clean it periodically. See the Care & Cleaning page. See similar questions...

Trex lumber contains no toxic preservatives and can be included and disposed of with normal construction debris. Trex Artisan Series Railing? profiles should not be burned, due to its material properties. See similar questions...

Trex decking performs well in extreme cold weather environments. However, because Trex decking is 50% plastic, it will be harder to nail when very cold. Under these conditions, pre-drilling is recommended. See similar questions...

The span charts and gapping procedures are designed to ensure that Trex decking performs well in extreme hot weather. When the temperature increases, Trex decking will become more flexible, and it will expand/contract slightly. For this reason, the span tables and gapping instructions should be closely followed. See the Installation section of our Literature Center. See similar questions...

Maine Deck? can be used for decking chassis work where there is compressive load bearing such as where the joists would be resting on an underlying concrete screed or beam. It can be used, following a full assessment of the application and full consideration to span of joists, to create suspended joists but this is best left to a professional installer. It is not recommended to use Maine Deck for major structural work unless there has been an assessment by a structural engineer. See similar questions...

Nascor has published a series of detailed floor span tables that take into account joist type, on centre spacing, glue vs. no glue and other factors. Download the Nascor Specifier Guide, where you will find the span tables on page 3. See similar questions...

x4 and 1x6 deck boards need to be installed on 16” centers. 5/4 x 4 and 5/4 x 6 deck boards need to be installed on 24” centers. See similar questions...

Trex Wood-Polymer lumber is just as easy to work with as wood, in some ways even easier. It can be cut, drilled, routed and nailed using standard tools. Carbide blades are recommended for best performance. See similar questions...

Virtually any deck fasteners work well with Trex decking. We recommend high quality screws or nails, such as stainless steel, ceramic coated or hot dipped galvanized to take advantage of Trex decking's longevity. As with wood, spiral shank nails provide better holding in Trex decking than do common nails. Pre-drilling is generally not required if you use self-tapping or deck screws and remain 1" from the edges of the board. Nail guns also work quite well. See similar questions...

Trex products have been approved for use in residential and commercial installations throughout North America. Trex decking has received a listing with the International Code Council Evaluation Service ICC ESR-1190 which covers BOCA, UBC, IBC, IRC and SBC codes. Trex has also been evaluated for use in Canada by the Canadian Construction Materials Centre. Please see Evaluation report 13125-R. See these reports in our Technical Information section.
